?2001 fairchild semiconductor corporation fsgye234r rev. b fsgye234r radiation hardened, segr resistant n-channel power mosfets fairchild star*power rad hard mosfets have been specifically developed for high performance applications in a commercial or military space environment. star*power mosfets offer the system designer both extremely low r ds(on) and gate charge allowing the development of low loss power subsystems. star*power gold fets combine this electrical capability with total dose radiation hardness up to 100k rads while maintaining the guaranteed performance for single event effects (see) which the fairchild fs families have always featured. the fairchild family of star*power fets includes a series of devices in various voltage, current and package styles. the portfolio consists of star*power and star*power gold products. star*power fets are optimized for total dose and r ds(on) while exhibiting see capability at full rated voltage up to an let of 37. star*power gold fets have been optimized for see and gate charge combining see performance to 80% of the rated volt age for an let of 82 with extremely low gate charge characteristics. this mosfet is an enhancement-mode silicon-gate power field effect transistor of the vertical dmos (vdmos) structure. it is specifically designed and processed to be radiation tolerant. the mosfet is well suited for applications exposed to radiation environments such as switching regulation, switching converters, power distribution, motor drives and relay drivers as well as other power control and conditioning applications. as with conventional mosfets these radiation hardened mosfets offer ease of voltage control, fast switching speeds and ability to parallel switching devices. reliability screening is available as either txv or space equivalent of mil-prf-19500. formerly available as type ta45232w. features ? 9a, 250v, r ds(on) = 0.225 ? uis rated total dose - meets pre-rad specifications to 100k rad (si) single event - safe operating area curve for single event effects - see immunity for let of 82mev/mg/cm 2 with v ds up to 80% of rated breakdown and v gs of 5v off-bias dose rate - typically survives 3e9 rad (si)/s at 80% bv dss - typically survives 2e12 if current limited to i as photo current - 4.0na per-rad (si)/s typically neutron - maintain pre-rad specifications for 1e13 neutrons/cm 2 - usable to 1e14 neutrons/cm 2 symbol packaging smd.5 ordering information rad level screening level part number/brand 10k engineering samples fsgye234d1 100k txv FSGYE234R3 100k space fsgye234r4 tm d g s data sheet december 2001
