PD - 90819A REPETITIVE AVALANCHE AND dv/dt RATED HEXFET® TRANSISTOR 500Volt, 0.45Ω , MEGA RAD HARD HEXFET International Rectifier’s RAD HARD technology HEXFETs demonstrate excellent threshold voltage stability and breakdown voltage stability at total radiaition doses as high as 1x106 Rads(Si). Under identical pre- and post-irradiation 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 operation within a few microseconds. Since the RAD HARD process utilizes International Rectifier’s patented HEXFET technology, the user can expect the highest quality and reliability in the industry. RAD HARD HEXFET transistors also feature all of the well-established advantages of MOSFETs, such as voltage control, very fast switching, ease of paralleling and temperature stability of the electrical parameters. They are well-suited for applications such as switching power supplies, motor controls, inverters, choppers, audio amplifiers and high-energy pulse circuits in space and weapons environments.

The hardness assurance program at International Rectifier comprises three radiation environments. Every manufacturing lot is tested in a low dose rate (total dose) environment per MIL-STD-750, test method 1019 condition A. International Rectifier has imposed a standard gate condition of 12 volts per note 6 and a VDS bias condition equal to 80% of the device rated voltage per note 7. Pre- and post- irradiation limits of the devices irradiated to 1 x 105 Rads (Si) are identical and are presented in Table 1, column 1, IRHN7450. Post-irradiation limits of the devices irradiated to 1 x 106 Rads (Si) are presented in Table 1, column 2, IRHN8450. The values in Table 1 will be met for either of the two low dose rate test circuits that are used. 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. High dose rate testing may be done on a special request basis using a dose rate up to 1 x 1012 Rads (Si)/Sec (See Table 2). International Rectifier radiation hardened HEXFETs have been characterized in heavy ion Single Event Effects (SEE) environments. Single Event Effects characterization is shown in Table 3. Table 1.
