PD - 93785A RADIATION HARDENED POWER MOSFET SURFACE MOUNT (LCC-28) IRHQ7110 100V, QUAD N-CHANNEL ® ™ RAD-Hard HEXFET MOSFET TECHNOLOGY Product Summary Part Number Radiation Level IRHQ7110 100K Rads (Si) RDS(on) 0.6Ω ID 3.0A IRHQ3110 300K Rads (Si) 0.6Ω 3.0A IRHQ4110 600K Rads (Si) 0.6Ω 3.0A IRHQ8110 1000K Rads (Si) 0.75Ω 3.0A TM LCC-28 HEXFET® MOSFET International Rectifier’s RAD-Hard technology provides high performance power MOSFETs for space applications. This technology has over a decade of proven performance and reliability in satellite applications. These devices have been characterized for both Total Dose and Single Event Effects (SEE). The combination of low RDS(on) and low gate charge reduces the power losses in switching applications such as DC to DC converters and motor control. These devices retain all of the well established advantages of MOSFETs such as voltage control, fast switching, ease of paralleling and temperature stability of electrical parameters.

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. Table 1.
