ID
International Rectifier’s (SEE) RAD HARD technology
HEXFETs demonstrate virtual immunity to SEE fail-
ure.Additionally, under identical pre- and post-radia-
tion 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 1012 Rads (Si)/Sec, and return to normal opera-
tion within a few microseconds. Since the SEE pro-

Features:
■ Radiation Hardened up to 1 x 105 Rads (Si)
■ Single Event Burnout (SEB) Hardened
■ Single Event Gate Rupture (SEGR) Hardened
cess utilizes International Rectifier’s patented HEXFET ■ Gamma Dot (Flash X-Ray) Hardened
technology, the user can expect the highest quality
■ Neutron Tolerant
and reliability in the industry.
■ Identical Pre- and Post-Electrical Test Conditions
■ Repetitive Avalanche Rating
■ Dynamic dv/dt Rating
■ Simple Drive Requirements
■ Ease of Paralleling
■ Hermetically Sealed
■ Surface Mount
■ Light-Weight
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 switch-
ing power supplies, motor controls, inverters, chop-
pers, audio amplifiers and high-energy pulse circuits
in space and weapons environments.
