       DIODES INCORPORATED REPORTS RECORD QUARTERLY REVENUES AND EARNINGS

Westlake Village, California - April 27, 2000 - Diodes Incorporated (Amex: DIO),
a manufacturer and supplier of discrete semiconductors to the automotive,
electronics, computing and telecommunications industries, today reported record
revenues and net income for its first quarter ended March 31, 2000.

Net sales for the quarter ended March 31, 2000 increased 71% to $27.3 million,
the highest quarterly sales in the Company's history, compared to $16.0 million
in the same period last year. Net income rose 349% to $3.1 million, or $0.51 per
diluted share, also the highest quarterly results in the Company's history,
compared to $690,000, or $0.13 per diluted share, in the first quarter of 1999.

C.H. Chen, President and CEO of Diodes Incorporated, credited the record sales
to a combination of stronger unit demand and more stable average sales prices.
Mr. Chen attributed the improvement in gross margin to 31.0% from 24.4% a year
ago to strengthened sales prices and the $4.5 million expansion announced last
summer in the Company's manufacturing facility in Shanghai, China. "We are
pleased with the success of the $4.5 million investment," said Mr. Chen, "and we
look forward to the contribution to margins when our $6.5 million expansion,
announced in December, comes on-line by mid 2000."

Selling, general and administrative expenses at 16.6% of sales reflect
separation compensation (equivalent to approximately $0.04 per share) paid to
the former President and Chief Executive Officer in March 2000. Absent the
separation compensation, said Mr. Chen, SG&A would have been 15.1% of sales,
compared to 19.5% a year ago.

"In light of the continued strong demand for the Company's products and the
increased output of the $6.5 million expansion, the growth outlook for year 2000
remains favorable," stated Mr. Chen. "Furthermore, we look forward to the
performance of our most recent $9 million expansion expected to be operational
at year-end," Mr. Chen concluded.

Diodes Incorporated (Amex: DIO) manufactures high-quality discrete semiconductor
devices and provides customer support to leading manufacturers in the
