REPETITIVE AVALANCHE AND dv/dt RATED
HEXFET
100 V olt, 0.045
International Rectifier’s 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 de vices are also
capable of surviving transient ionization pulses as high
as 1 x 10
tion within a few microseconds. Since the RAD HARD
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 MOSFETs, such as
voltage control, very fast s witching, ease of par alleling
and temperature stability of the electrical parameters.
They are well-suited for applications such as switching power supplies, motor controls, inver ters, choppers, audio amplifiers and high-energy pulse circuits
in space and weapons environments.
