EXHIBIT 99.51 Diodes Incorporated FOR IMMEDIATE RELEASE Diodes Incorporated Introduces New Low-Capacitance Data Line Protection Device Westlake Village, California, April 23, 2002 - Diodes Incorporated (Nasdaq: DIOD), a leading manufacturer and supplier of high quality discrete semiconductors, today announced the launch of a new low-capacitance data line protection device. The ability to preserve data integrity makes the DLP05LC ideally suited for cable set-top boxes and high-speed data transmission lines where the absence of signal degradation is of primary importance. Other targeted end-equipment applications that will benefit from this product include hand-held wireless systems and portable electronics, including PDAs and laptop computers and other computer peripherals and digital interfaces such as USB and SCSI ports. Available in the popular subminiature SOT-23 surface mount package, the DLP05LC offers transient protection of up to 300 Watts of Peak Pulse Power and features extremely low capacitance of 1.6pF, typical. The low capacitance of the device helps to minimize signal attenuation and data corruption during data transmission. The measurement of transient protection for data, signal and Vcc bus conforms to industry-standard IEC 61000-4-2, level 4 for ESD and IEC 61000-4-4 for EFT. The new product line will occupy a unique position in the market place, as there are currently no exact equivalents available. Mark King, Vice President of Sales and Marketing at Diodes Incorporated, confirmed that there has been "a very positive response from our customer base and we have already received production orders. In addition, we are exploring the possibility of expanding the availability of the protection circuit to other surface mount packages." "This is another example of the benefits realized from our ongoing commitment to research and development programs," continued King. "These efforts are enabling us to bring exciting and innovative products to market and increasing our ability to penetrate new industry sectors. "By working in tandem with our customer base and responding to their direct needs, we are developing proprietary product lines that add significant value to our relationships while at the same time enhancing the breadth and quality of our product range."
