International Rectifier has introduced the world's first 1000V radiation-hardened power MOSFET.
The devices' lower quiescent current of 340uA, undervoltage lockout feature and maximum junction temperature of 150C enable more robust and reliable performance.
Additionally, the IRS2117 and IRS2118 feature common mode rejection of 50V/ns.
Proprietary latch immune CMOS technologies enable rugged monolithic construction.
The output driver, which is logic input compatible with standard CMOS outputs, features a high-pulse current buffer stage designed for minimum crossconduction.
The floating channel can be used to drive an N-channel power MOSFET or IGBT in the high-side or low-side configuration, operating up to 600V.
The new devices use IR's advanced high-voltage IC process which incorporates next-generation high-voltage level-shifting and termination technology to deliver superior electrical overstress protection and higher field reliability.
