Additionally, under identical pre- and post-radiation 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 SEE 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 uses two radiation environments. Both pre- and post-radiation performance are tested and specified using the same drive circuitry and test conditions in order to provide a direct comparison. It should be noted that at a radiation level of 1 x 105 Rads (Si), no change in limits are specified in DC parameters. Every manufacturing lot is tested in a low dose rate (total dose) environment per MlL-STD-750, test method 1019. International Rectifier has imposed a standard gate voltage of 12 volts per note 6 and a VDSS bias condition equal to 80% of the device rated voltage per note 7. Pre- and post-radiation limits of the devices irradiated to 1 x 105 Rads (Si) are identical and are presented in Table 1. The values in Table 1 will be met for either of the two low dose rate test circuits that are used. Table 1.
