Description

Power MOS 8™ APT37F50B is a high speed, high voltage N-channel switch-mode power MOSFET. This 'FREDFET' version has a drain-source (body) diode that has been optimized for high reliability in ZVS phase shifted bridge and other circuits through reduced trr, soft recovery, and high recovery dv/dt capability. Low gate charge, high gain, and a greatly reduced ratio of Crss/Ciss result in excellent noise immunity and low switching loss. The intrinsic gate resistance and capacitance of the poly-silicon gate structure help control di/dt during switching, resulting in low EMI and reliable paralleling, even when switching at very high frequency.
