Micross develops hermetic packaging for SemiSouth SiC ultra high temperature apps to 260°C

AUSTIN & STARKVILLE, USA: Micross Components Inc. and SemiSouth Laboratories Inc. announced a collaborative effort to expand SemiSouth’s line of Silicon Carbide (SiC) Power JFETs and Schottky Diodes.

SemiSouth will provide select JFET and diode die to Micross for packaging and test in metal hermetic packages, Micross will then offer these value-added hermetically packaged versions aimed at the Military, Aerospace and Down-hole Drilling markets. Micross and SemiSouth will draw on each other’s respective strengths in order to promote SiC product sales synergy in the worldwide marketplace.

Micross plans to offer screening of the JFETs and Schottky Diodes to military and space specifications such as MIL-PRF-19500 equivalent initially and eventually offering standard certified MIL-PRF-19500 products in the future.

The initial Micross SiC product offering will include four 1200V and one 1700V JFETs with 1250C continuous max drain current capability of 4 to 50 amps and low RDSon, and four 1200 volt Schottky diodes capable of 5 to 30 amps continuous forward current. Operating junction temperature range is -550C to +2000C (TJ), with special screening up to 2600C upon request.

“This is a significant product addition to our Military & Aerospace products family that will better serve the Satellite customer with state-of-the-art SiC technology for High Power FETs & Diodes. With our Hermetic packaging offering, this also expands the product use for extreme temperatures seen in deep down hole drilling of up to 260oC,” says Jeff Kendziorski, director of Marketing and New Product Development, Micross Components Inc.

Larry Wallace, GM – Semiconductor of Micross Components, Inc. added, “We are excited to be working with a leader in Silicon Carbide manufacturing such as SemiSouth.”

“We are continuing to search for ways to sell our SiC power electronics products in to hi-rel and mil-aero customers, and are pleased to be working with a well-known Hi-Reliability products vendor such as Micross,” says SemiSouth Laboratories CTO and VP of Business Development Jeff Casady.
