International Rectifier’s (SEE) RAD HARD technology HEXFETs demonstrate virtual immunity to SEE fail­ure. Additionally , under identical pre- and post-radia­tion test conditions, International Rectifier’s RAD HARD HEXFETs retain identical electrical specifications up to 1 x 105 Rads (Si) total dose. No compensation in gate drive circuitry is required. These devices are also capable of surviving transient ionization pulses as high as 1 x 10
12
Rads (Si)/Sec, and return to normal opera­tion within a few microseconds. Since the SEE pro­cess utilizes International Rectifier’s patented HEXFET technology, the user can expect the highest quality and reliability in the industry.
RAD HARD HEXFET transistors also feature all of the well-established advantages of MOSFET s, such as volt­age control, very fast switching, ease of paralleling and temperature stability of the electrical parameters.
They are well-suited for applications such as switch­ing power supplies, motor controls, inverters, chop­pers, audio amplifiers and high-energy pulse circuits in space and weapons environments.
