MEGA RAD HARD
REPETITIVE AVALANCHE AND dv/dt RATED
HEXFET® TRANSISTOR
Product Summary
200 Volt, 0.10Ω, MEGA RAD HARD HEXFET
International Rectifier’s MEGA RAD HARD technology
HEXFET power MOSFETs demonstrate excellent
threshold voltage stability and breakdown voltage sta-
bility at total radiation doses as high as 1 x 106 Rads
(Si). Under identical pre- and post-radiation test con-
ditions, International Rectifier’s RAD HARD HEXFETs
retain identical electrical specifications up to 1 x 105
Rads (Si) total dose. At 1 x 106 Rads (Si) total dose,
under the same pre-dose conditions, only minor shifts
in the electrical specifications are observed and are so
specified in table 1. No compensation in gate drive cir-
cuitry is required. In addition, these devices are 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 International Rectifier RAD HARD HEXFETs has dem-
onstrated virtual immunity to SEE failure. Since the
MEGA 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 volt-
age 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, au-
dio amplifiers and high-energy pulse circuits in space
and weapons environments.
