International Rectifier Debuts R6 RAD-Hard MOSFETs

International Rectifier Corp. (IR, El Segundo, CA) debuted its new R6™ line of high-reliability (HiRel) 100 V, 150 V, 200 V, and 250 V radiation-hardened (RAD-Hard™) MOSFETs for power-management circuits. The R6 Line is suitable for dc-dc converters, motor controls, and solid-state switching circuits with input voltages of 24 V to 48 V in launch vehicles, satellites, and other demanding applications.

The new R6 MOSFETs have SEE ratings to LET of 90 MeV, and improved prompt dose response and SEE absorption versus other equivalent devices. In addition, the new devices are optimized for use in hybrid MIL-PRF-38534 Class K modules for satellite applications, including low-Earth orbit, middle-earth orbit, geostationary-earth orbit, and deep-space missions. Devices are available in surface-mount and new TO-254 and TO-257 packages. Tabless TO-254 and TO-257 packages are also available.

The new R6 mid-voltage, RAD-Hard MOSFETs are available now. Pricing begins at $290.63 each for the IRHNJ67130 in 1,000-unit quantities.
