RADHARD
-60Volt, 0.055Ω, RAD HARD HEXFET
Product Summary
International Rectifier’s P-Channel RAD HARD technology
HEXFETs demonstrate excellent threshold voltage stability
and breakdown voltage stability at total radiation doses as
high as 105 Rads (Si). Under identical pre- and post-radia-
tion test conditions, International Rectifier’s P-Channel 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 sur-
viving transient ionization pulses as high as 1 x 1012 Rads
(Si)/Sec, and return to normal operation within a few micro-
seconds. Single Event Effect (SEE) testing of International
Rectifier P-Channel RAD HARD HEXFETs has demon-
strated virtual immunity to SEE failure. Since the P-Chan-
nel RAD HARD process utilizes International Rectifier’s
patented HEXFET technology, the user can expect the high-
est quality and reliability in the industry.

P-Channel RAD HARD HEXFET transistors also feature
all of the well-established advantages of MOSFETs, 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 amplifi-
ers and high-energy pulse circuits in space and weapons
environments.
