REPETETIVE AVALANCHE AND dv/dt RATED
HEXFET® TRANSISTOR
RAD HARD
Product Summary
-200 Volt, 0.8Ω, RAD HARD HEXFET
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 surviving transient ionization pulses as high as 1 x 1012
Rads (Si)/Sec, and return to normal operation within a few
microseconds. Single Event Effect (SEE) testing of Inter-
national Rectifier P-Channel RAD HARD HEXFETs has
demonstrated virtual immunity to SEE failure. Since the
P-Channel RAD HARD process utilizes International
Rectifier’s patented HEXFET technology, the user can ex-
pect the highest quality and reliability in the industry.
