Exhibit 99.57 Diodes Incorporated FOR IMMEDIATE RELEASE Diodes Incorporated Introduces Line of 3 & 5 Amp Powermite(R)3 Schottky Barrier Rectifiers o Compact, thermally superior replacement for SMC and D-Pak parts Westlake Village, California - October 23, 2002 - Diodes Incorporated, (Nasdaq: DIOD) a leading manufacturer and supplier of high quality discrete semiconductors, today announced the release of a comprehensive line of three Ampere and five Ampere Powermite(R)3 Schottky barrier rectifiers. The new Powermite(R)3 Schottky barrier line, which uses patented packaging technology licensed from Microsemi, Inc. (Nasdaq: MSCC), will be manufactured at Diodes' state-of-the-art facilities in Mainland China. Diodes' Powermite(R)3 parts offer a significant reduction in required board space and superior thermal performance as compared to industry-standard SMC and D-Pak packages. The Powermite(R)3 package has a very low profile of only 1.1mm, which allows it to be used in many portable applications in which the 2.3mm profile of SMC and D-Pak is prohibitive. In addition, the Powermite(R)3 package requires approximately half the board space of the SMC and only 40% of the D-Pak. This gives the Powermite(R)3 package a high Power Density value of 55mW/mm2, which is over double the values for D-Pak or SMC. "This new line illustrates Diodes' continued expansion into next-generation discrete technologies and the benefits of our vertical integration strategy. By applying Powermite(R)3 packaging to broad-based devices, we expect to deliver major performance improvements for applications where space is at a premium, such as notebooks, battery chargers, GPS units, TFT-LCD panels, quarter-brick and half-brick power supplies," said Mark King, Vice President of Sales and Marketing at Diodes Incorporated. The 3 Amp series consists of: o SBM340, a 40-volt device o MBRM360, a 60-volt device o MBRM3100, a 100-volt device The 5 Amp series consists of: o SBM540, a 40-volt device o MBRM560, a 60-volt device o MBRM5100, a 100-volt device "Shrinking power components is the next phase of discrete miniaturization, and the addition of these devices gives Diodes the most comprehensive 3 and 5 Amp surface-mount Schottky barrier rectifier product line in the discrete semiconductor industry," continued King. "Our strategy is to develop devices that add value for high-end, high-performance applications but are also competitive for broader, high-volume markets. Our flexible, low-cost manufacturing allows us to execute our strategy and meet customer needs." Many additional new Powermite(R)3 products are currently under development and are scheduled for release soon, including dual Schottky barrier rectifiers, high voltage low leakage Schottky barrier rectifiers, and ultra-fast and standard recovery glass passivated rectifiers.
