-200 Volt, 0.315, RAD HARD HEXFET
International Rectifier's P-Channel RAD HARD technology HEXFETs demonstrate excellent threshold voltage stability and breakdown voltage stability at total radiation doses as high as 10 5 Rads (Si). Under identical pre- and postradiation test conditions, International Rectifier's P-Channel 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 10 12 Rads (Si)/Sec, and return to normal operation within a few microseconds. Single Event Effect (SEE) testing of International Rectifier P-Channel RAD HARD HEXFETs has demonstrated virtual immunity to SEE failure. Since the PChannel RAD HARD process utilizes International Rectifier's patented HEXFET technology, the user can expect the highest quality and reliability in the industry. P-Channel 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, inver ters, choppers, audio amplifiers and high-energy pulse circuits in space and weapons environments.

Radiation Performance of P-Channel Rad Hard HEXFETs

Radiation Characteristics
International Rectifier Radiation Hardened HEXFETs are tested to verify their hardness capability. The hardness assurance program at Inter national Rectifier uses two radiation environments. 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 postradiation 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.
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 10 5 Rads (Si), no change in limits are specified in DC parameters. High dose rate testing may be done on a special request basis, using a dose rate up to 1 x 1012 Rads (Si)/Sec. International Rectifier radiation hardened P-Channel HEXFETs are considered to be neutron-tolerant, as stated in MIL-PRF-19500 Group D. International Rectifier PChannel radiation hardened HEXFETs have been characterized in heavy ion Single Event Effects environment and the results are shown in Table 3.
