Following the decision by Siliconix to close their Santa Clara, CA facility, ES Components acquired all available inventory, work-in-progress and die/wafers. Also included was the product documentation/traceability and equipment used on the Siliconix line in Santa Clara, CA. ES Components estimates the current die/wafer inventories can support the market requirements more than 10 years and in many cases many life times.
ES Components manages assembly and test of these devices through facilities with approved DLA lab suitability such as VPT Components “VPT”, a division of SST Components, Inc. (“SST”) in Billerica, MA and Microchip Technology (Thailand) Co., Ltd. (“MMT”). VPT has completed the qualification of parts to MIL-PRF-19500/476 (2N5114 – 2N5116), 19500/430 (2N5545 – 2N5547) and MIL-PRF19500/385 (2N4856 – 2N4861). Additional quals to 19500/547 (2N6660 – 2N6661) in a surface mount UB package is in process. The data has been submitted to DLA and approval is expected soon. In addition, a radiation tolerant option of parts that fall under MIL-PRF-19500/385 has been released. All “Siliconix Inside” products produced by VPT will be sold exclusively through ES Components.
