IRVINE, Calif., Aug 12, 2009 (GlobeNewswire via COMTEX News Network) -- Microsemi Corporation (Nasdaq:MSCC), a leading manufacturer of high performance analog/mixed signal integrated circuits and high reliability semiconductors, announced today that space-level qualification has been granted by the Defense Supply Center Columbus (DSCC) on Microsemi's first family of radiation-hardened power MOSFET devices.

With this initial product qualification, Microsemi is releasing a full line of space level radiation-hardened power MOSFET devices to complement its existing line of high reliability, non radiation-hardened, hermetic MOSFETs that already have QML qualification from DSCC.

The DSCC-approved JANSF2N7382 and the JANSF2N7389 qualifications confirm that Microsemi's 100V, P-Channel Power MOSFETs are radiation hardened to meet the total dose requirements of MIL-PRF-19500/615 and MIL-PRF-19500/630 up to 300,000 RAD(Si).

"We are extremely pleased to have received these qualifications from DSCC, enabling us to launch this new product line," said Doug Milne, Vice President and General Manager of Microsemi's Lawrence, Massachusetts facility. He added; "Space customers have been searching for alternatives in the radiation hardened MOSFET market and now Microsemi has stepped up to support this demand."

Microsemi also announced the immediate release of a family of 10 other radiation hardened power MOSFETs as standard products while their DSCC qualifications are in process. All devices are constructed to meet the demanding requirements of space applications. Radiation hardened MOSFETs are primarily used in power supplies, power converters, motor controls, and other power switching applications. These products use the latest wafer fabrication technologies developed in Microsemi's Garden Grove, CA facility.

Features include:

* Total dose hardened to 300K RAD(Si)

* 100V & 200V N-Channel devices

* Standard hermetic package outlines in both through-hole and surface

mount configurations

* Fast switching

* Low gate charge

* Single event hardened
