Microsemi Extends Its New Radiation Hardened Transistor Product Line

September 9, 2009

IRVINE, CA (Globe Newswire) -- Microsemi Corporation (Nasdaq:MSCC), a leading manufacturer of high performance analog/mixed signal integrated circuits and high reliability semiconductors, announced today that DSCC qualification has been granted on their JANSR2N3439 and JANSR2N3440 radiation hardened medium power transistors.

With these latest approvals Microsemi has now qualified an additional 54 radiation hardened transistor products over the last year. This includes 44 new packaged device types and 10 newly-qualified radiation hardened die types for hybrid packaging applications.

These general purpose, small signal and medium power bipolar transistors are primarily used in aerospace, defense and satellite communication applications. They are specifically designed to perform in the severe environmental and radiation conditions that exist in space where component selection is essential to mission success.

Microsemi has worked closely with the Defense Supply Center Columbus (DSCC) to define the test specifications within standard military drawings (MIL-PRF-19500 slashsheets) so that customers can be assured of the radiation performance capabilities of these products.

Features include:

NPN & PNP
Low and medium power
Standard hermetic package outlines in both through-hole and surface mount configurations
Radiation Hardened for Total Ionizing Dose performance of 100,000 (R) and 300,00 (F) RAD(Si) as shown below
Space level Quality

The new product qualifications include:

Products are offered up to Radiation Hardness Assurance (RHA) Level F (Total ionizing dose = 300K RAD(Si) or Level R (Total ionizing dose = 100K RAD(Si) as indicated above. All lower total dose levels are also available:

A full description of these devices and technical data sheets are available on the Microsemi website: www.microsemi.com.
