INTERNATIONAL Rectifier (IR) has introduced the R6 line of high-reliability (HiRel) 100V, 150V, 200V and 250V radiation-hardened (RAD-Hard) MOSFETs for power management circuits.
The R6 MOSFETs have SEE ratings to LET of 90MeV and improved prompt dose response and SEE absorption versus other equivalent devices.
In addition, the devices are optimizsed for use in Hybrid - MIL-PRF-38534 "Class K" modules for satellite applications, including low Earth orbit (LEO), middle earth orbit (MEO), geostationary earth orbit (GEO) and deep space missions.
The R6 products are available in surface-mount as well as new low-ohmic TO-254 and TO-257 packages. Tab-less TO-254 and TO-257 packages are also available.
