200 Volt, 0.10Ω, MEGA RAD HARD HEXFET

International Rectifier’s MEGA RAD HARD technology HEXFET power MOSFETs demonstrate excellent threshold voltage stability and breakdown voltage stability at total radiation doses as high as 1 x 106 Rads (Si). 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. At 1 x 106 Rads (Si) total dose, under the same pre-dose conditions, only minor shifts in the electrical specifications are observed and are so specified in table 1.
