HARD HEXFETs retainidenticalelectrical specifications up
Features:
to 1 x 105 Rads (Si) total dose. No compensation in gate
drive circuitry is required. In addition 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
International 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 HEXFETtechnology, the user can expect
the highest quality and reliability in the industry.
