Dr. Keh-Shew Lu, President and CEO of Diodes

Thank you, Crocker.

Welcome everyone, and thank you for joining us today.

We are very pleased to report another quarter of solid results, with Diodes
continuing to outperform the overall industry. During the second quarter we
made progress on a number of important areas of our business strategy, as we:

      o     restructured our analog manufacturing operations from Taiwan to
            China to improve efficiency,

      o     launched a number of new innovative products targeted at high growth
            end markets, and

      o     delivered solid results for our shareholders.

Second quarter highlights include the following results:

o     Revenues increased 16% year-over-year, and 4.6% sequentially to a new
      record of $96.3 million

o     Adjusted net income increased 16% year-over-year to $15 million, or 53
      cents per share, up from $12.9 million, or 45 cents per share, in the
      second quarter of 2006, and 50 cents in the first quarter of 2007

o     And, we announced another 3-for-2 stock split which became effective two
      days ago


                                        3



Our second quarter results demonstrate that Diodes has continued to outperform
the overall market and continues to take share of our key markets, as market
conditions improved and demand picked up in Asia following the seasonally slow
first quarter.

During the quarter we moved and consolidated our analog manufacturing operations
from Hsinchu, Taiwan into our facilities in China, to drive operational
efficiencies and leverage the infrastructure already in place at our high volume
Shanghai manufacturing facilities.

During the second quarter we introduced several innovative new products
leveraging our Super Barrier Rectifier technology, called SBR(R), technology
packaged in Diodes' proprietary high performance Power(TM)DI, and in the
Ultra-Miniature DFN package.

We also introduced new Low-Voltage Operational-Amplifiers and Comparators, a
second generation switch for the cell phone and the portable consumer
electronics market, in addition to a new high-efficiency DC-DC Buck Converter.

Later Mark will discuss new product launches that reaffirm our commitment to
research and development for next-generation technologies designed to meet the
growing demand for higher efficiencies and smaller form factor in the fastest
growing end markets.


                                        4



We ended the quarter with over $350 million in cash and short-term investments,
which gives us enough financial flexibility to continue to pursue acquisition
candidates within our targeted market segments that fit our criteria to
accelerate our profitable growth.

As we enter the third quarter, we expect to continue to build on our strengths
as we benefit from synergies between our discrete and adjacent analog segments,
and continue to focus on customer centric innovation and efficient manufacturing
to deliver profitable growth.

With that, I'm going to turn the call over to Carl to discuss our financial
results in more detail.

2Q 2007 Financials: Carl Wertz

Thanks, Dr. Lu, and good morning everyone.

As Dr. Lu mentioned, in the second quarter Diodes continued to outperform the
industry, and to make solid progress in the execution of our strategy. In the
second quarter of 2007 both revenue and profits were up on a year-over-year
basis.

      o     Revenues for the second quarter reached an all-time high of $96.3
            million, an increase of 16.4% from the second quarter of 2006. On a
            sequential basis our revenues were up 4.6%, at the high end of our
            guidance range. New product sales accounted for 33.5% of revenue,
            compared to 24.9% just one year ago.

      o     Gross profit for the second quarter increased 11.8% to $30.7
            million, compared to the same period last year. On a sequential
            basis, gross profit dollars were up 3.9% as demand picked up with a
            7.2% increase in units. Gross margin was off 20 basis points
            sequentially at 31.9% as the ASPs declined 2.4%.


                                        6



            Over the course of 2007 we should see opportunities for margin
            expansion as we transitioned analog production from the currently
            outsourced packaging to our state-of-the art facilities, and as we
            benefit from the consolidation of our analog manufacturing at our
            facilities in Shanghai, and introduce newly developed products.

      o     Selling, General & Administrative expenses for the quarter were
            13.9% of revenue or $13.4 million, compared to 14.2% of revenue or
            $11.8 million, in the comparable quarter last year. Included in
            second quarter 2007 SG&A was $1.2 million in non-cash, FAS123R,
            share-based compensation. In the earnings release we have
            included a table to reconcile the impact of share-based compensation
            expense to our reported results.

      o     Research and development investment in the quarter was $3.2 million,
            or 3.3% of revenue, compared to $2.1 million, or 2.5% of revenue, in
            the second quarter of 2006. The R&D increase was primarily the
            result of the APD acquisition in the fourth quarter of 2006. We
            continue to enhance our research and development capabilities to
            support our broader market focus and position us for our profitable
            growth objectives.


                                        7



      o     Restructuring charges were $1.8 million as we consolidated and moved
            our Taiwan analog operations into our China manufacturing
            facilities.

      o     Our effective income tax rate in the second quarter was 14.8%,
            compared to 16.5% for the previous quarter, and 19.8% for the same
            period last year. The lower effective tax rate reflects additional
            tax planning efforts aimed at lower planned foreign earnings
            repatriations in 2007. Going forward, we currently anticipate our
            consolidated tax rate to be in the mid teens.

      o     Adjusted net income, which excludes the one-time restructuring costs
            of 1.8 million and $1.4 million in FAS123R, non-cash stock option
            expense increased 16.2% year-over-year to $15 million, or $0.53 per
            diluted share (and $0.35 split adjusted), up from $12.9 million, or
            $0.45 per diluted share (and $0.30 split adjusted), in the second
            quarter of 2006, and $0.50 per diluted share (or $0.33 split
            adjusted) last quarter.

      o     Cash flow from operations for the quarter was $21.5 million, a 19%
            increase compared to $18 million for the same period last year.


                                        8



      o     Turning to the balance sheet, at the end of the quarter we had $352
            million in total cash and short-term investments, $420 million in
            working capital, and $239 million in long-term term debt including
            the convertible bond.

      o     Our total debt-to-equity ratio was 1.0 for the second quarter, while
            our total debt-to-assets ratio was 50%.

      o     Inventories ended the second quarter at $48.6 million, with
            inventory days at 63 compared to 61 days the previous quarter and we
            believe we are properly positioned to support our revenue growth in
            the third quarter.

      o     Accounts receivable days were 80 days in the second quarter compared
            to 81 days in the prior quarter.

      o     Capital expenditures for the current quarter were $14.9 million and
            $27.3 million for the first half of 2007, representing 14.5% of
            revenue, ahead of our full-year estimate as we continue to invest
            for expected growth. Depreciation expense for the second quarter and
            first six months of 2007 was $6.2 million and $12.0 million,
            respectively.


                                        9



We had originally planned our 2007 Capital Expenditures to be at the upper end
of our 10-12% model, and front-loaded in the first half of the year to allow us
to take advantage of projected second half growth prospects.

Our first half actual at 14.5% of revenue is in line with this plan. We are
continuing to evaluate our second half Capital Expenditures plans in light of
our original plan and the developing second half market environment.

Turning to our Outlook...

With the backdrop of improved market conditions and as we move into the
seasonally stronger part of the year, we remain confident that Diodes' focus on
the application specific standard products within the broad discrete and analog
market, while leveraging our cost efficient manufacturing base, positions us
well to continue to deliver profitable growth in the quarters ahead.

Coming off a quarter where we saw expanding demand, and with a book-to-bill
ratio above one, we currently expect to see third quarter 2007 revenue grow
another 6 to 9% sequentially, with slightly improved gross profit margin.


                                       10



With that said, I'm now going to turn the discussion over to Mark King, our
Senior VP of Sales and Marketing. Mark will discuss our new products, market
opportunities, and give you a view on the direction of the general marketplace.

Markets and Growth Strategies - Mark King

Thanks, Carl and good morning.

During the second quarter we made solid progress along our new product road map
in the discrete, analog and hall sensor categories. Sales of new products
reached 33.5% of total, driven by products in our QFN and PowerDI(TM) lines, as
well as our analog and Zener lines.

We had an exceptionally active period for new product introductions, releasing
54 products from 13 product families in the quarter, including 11 SBR(R), 6
analog and 3 hall-sensor devices. Earlier in the quarter, we launched a new
series of low threshold MOSFETs, optimized for low voltage applications common
to ultra-miniature electronic devices.

We also made several new additions to our SBR(R) product family leveraging our
proprietary high performance PowerDI(TM) as well as our ultra-miniature DFN1006
packages. The combination of our SBR(R) technology with our advanced
ultra-miniature packaging capability has pushed the boundaries of innovation.


                                       12



During the second quarter we also introduced a new family of high-efficiency
ultra-low V(F) SBR(R) rectifiers targeting the PC power supply market. And more
recently, we launched the breakthrough 300V SBR(R) targeted at high power
applications in consumer electronics, industrial applications and telecom, among
others.

We also launched dual and quad low-voltage Op-Amp and Comparators for providing
critical circuit functions targeted at the rapidly expanding low-voltage product
segment. And we launched the AH1884, a new hall sensor switch for small portable
applications that offers greater performance than comparable products available
in the market.

In addition, we expanded our portfolio of high-efficiency DC-DC PWM Buck
Converters with the introduction of the AP1533, a 1.8A Asynchronous Converter
for use in a wide range of computing and consumer electronic applications.

With these product introductions, Diodes continues to drive technology forward,
setting new industry standards, expanding our product breath, and positioning us
well to deliver on our profitable growth objectives.


                                       13



Starting with Geographic Breakout...

Market share for Diodes' products remained at all time highs in the second
quarter.

Asia sales volume increased sequentially driven by OEM sales in the consumer and
computer segments, and contributed 75% of our second quarter sales; core end
equipment categories such as LCD TVs and monitors, notebooks, set-top boxes and
datacom were up strongly in the quarter, whereas digital audio players and
motherboards showed modest improvements.

Distributor point of purchase, or POP, was down in the second quarter, with
rising point of sale, POS, and with distributor inventories at healthy levels.

Next, in North America...

Sales were down sequentially coming off a stronger than expected first quarter.
OEM sales, however, were up 2% driven by set-top box, security and portable
medical devices. OEM strength in North America has been partially offset by
continued movement towards Asian assembly. North America distributor POP and POS
were down 5% in the second quarter with inventory down in line with sales.

Design activity in the quarter was high with 130 new part qualifications at 35
customers, with 16 of these being analog designs.


                                       14



Wafer sales were down 17% as we consumed more wafer internally, while wafer ASPs
were down 7%.

Finally, in Europe...

The market was down slightly during the second quarter coming off a record first
quarter, with OEM sales down 4% and distributor point of purchase down 3%
sequentially. Distributor point of sales continued to climb, growing 21% to a
new record. Europe accounted for 4% of sales in the quarter.

Our momentum in Europe continue to expand with 38 design wins at 21 accounts in
the second quarter, including 1 significant SBR(R) win, 7 new analog design
wins, 1 hall sensor win, and a key ASMCC win.

We are particularly pleased with our new distribution agreement with SILICA, an
Avnet company, and one of the largest distributor of semiconductor products in
Europe. SILICA's highly specialized semiconductor focus and extensive local
presence will improve our ability to service our customer's logistic
requirements, enhance our competitiveness and strengthen Diodes' brand
recognition.


                                       15



Moving to Market Segments...

For the second quarter, our segment breakout was: 38% consumer, 36% computer and
peripherals, 15% telecom, 10% industrial, and 2% automotive.

Now I'll go into Design Wins...

Design activity is very positive. We had multiple design wins at over 70
accounts globally. The activity around our new SBR(R) technology continues to be
strong across all regions. We had significant design wins at 5 accounts in the
quarter for end use applications ranging from printers to welding equipment.
More importantly, the in process design volume is quite high and initial
customer input continues to present new product opportunities.

Design wins for our commodity analog products continue to gain traction in North
America and Europe. In the second quarter we had wins in Wireless LAN and VoIP,
as well as cable modem and graphic cards. In Asia, standard analog design
activity was strong in LCD TV and motherboards, set-top boxes, and portable DVD.

We continue to see strong interest in our Omnipolar hall sensor platform and the
pending design activity is quite high. We had wins in cell phones, notebooks,
industrial control, and personal hygiene devices. The product development on
this line has been brisk in response to specific customer requirements and we
expect this line will become a key driver in the quarters to come


                                       16



On the discrete side we had a very strong quarter in our propriety PowerDI line
with wins in solar panel, LCD module, DC Fan, digital audio player, and
industrial timing to name a few. We also continue to see robust and expanded
interest in out DFN leadless packages especially our new 0.4mil thick devices,
our recently announced low threshold MOSFET line and our application specific
line.

The synergy between the analog and discrete product lines continues to present
opportunities with our customers.

In Summary...

Diodes made excellent progress in implementing our strategy of innovation and
profitable growth with:

      solid financial results,
      a record level of design wins,
      best-in-class product launches,
      and expanded distribution capabilities.


                                       17



Our high volume of new product launches and design wins provide us confidence we
will sustain this positive momentum going into the third quarter.

In the second half of 2007, we expect to continue to expand our market share in
both the discrete and standard analog markets, realize further cost and
cross-selling synergies from our prior acquisitions, and accelerate the pace of
product innovation through our expanded global R&D platform.

In addition, we continue to actively evaluate acquisitions that could accelerate
our growth, by enhancing our product breadth, expanding our customer base and
broadening our geographic footprint.

With that, let's open the floor to questions. Operator?
