Logic Level Power
Mosfets provide simple solution to interfacing CMOS
and TTL control circuits to power devices in space
and other radiation environments. The threshold
voltage remains within accptable operating limits
over the full operating temperature and post radiation.
This is achieved while maintaining single event gate
rupture and single event burnout immunity.
These devices are used in applications such as
current boost low signal source in PWM, voltage
comparator and operational amplifiers.

Radiation Characteristics
Pre-Irradiation
IRHLF770Z4, 2N7621T2
International Rectifier Radiation Hardened MOSFETs are tested to verify their radiation hardness capability.
The hardness assurance program at International Rectifier is comprised of two radiation environments.
Every manufacturing lot is tested for total ionizing dose (per notes 5 and 6) using the TO-3 package. Both
pre- and post-irradiation performance are tested and specified using the same drive circuitry and test
conditions in order to provide a direct comparison.
