Microsemi Corp. MOSFET APT37F50S

APT37F50S is a 500V, 37A N-channel FREDFET power MOSFET in a TO-247 package, designed for high-efficiency switching applications such as ZVS phase-shifted bridges, boost converters, and flyback circuits. It features a maximum on-resistance of 0.15Ω at 10V gate drive and 18A drain current, a reverse recovery time of 250ns at 25°C, and an avalanche energy rating of 780mJ. The device has a gate charge of 145nC, low Crss/Ciss ratio for improved noise immunity, and operates within a junction temperature range of -55°C to 150°C. It is RoHS compliant and rated for continuous drain current of 24A at 100°C case temperature. Thermal resistance from junction to case is 0.24°C/W.
