PD-9736 RADIATION HARDENED LOGIC LEVEL POWER MOSFET THRU-HOLE (4-LEAD FLAT PACK) 2N763M2 IRHLA797Z4 6V, Quad P-CHANNEL TECHNOLOGY Product Summary Part Number Radiation Level RDS(on) ID IRHLA797Z4 K Rads (Si).36Ω -.56A IRHLA793Z4 3K Rads (Si).36Ω -.56A 4-Lead Flat Pack International Rectifier s R7 TM 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 acceptable 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 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-39 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. Table.
