APT20F50B is a 500V, 20A N-channel FREDFET power MOSFET in a TO-247 package, designed for high-reliability switch-mode applications such as ZVS phase-shifted bridges, boost converters, and flyback circuits. It features a reverse recovery time of ≤200ns, low gate charge of 75nC, and reduced Crss/Ciss ratio for improved noise immunity and switching efficiency. The device has a maximum drain-source on-resistance of 0.30Ω at 10A and 10V gate drive, an avalanche energy rating of 405mJ, and operates from -55°C to 150°C junction temperature. It is RoHS compliant and rated for 290W power dissipation at 25°C case temperature with a thermal resistance of 0.43°C/W junction-to-case. Mounting torque is specified at 1.1N·m for the TO-247 package.
Power MOS 8™ 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.
