hexfet ? technology international rectifier?s radhard tm hexfet ? mosfet 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 r ds(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. pd-91398b IRHNA7360SE pre-irradiation 2 www.irf.com electrical characteristics @ tj = 25c (unless otherwise specified) parameter min typ max units test conditions bv dss drain-to-source breakdown voltage 400 ?
