N-Channel FREDFET
Power MOS 8TM 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.

3 Pulse test: Pulse Width < 380s, duty cycle < 2%. 4 Co(cr) is defined as a fixed capacitance with the same stored charge as COSS with VDS = 67% of V(BR)DSS. 5 Co(er) is defined as a fixed capacitance with the same stored energy as COSS with VDS = 67% of V(BR)DSS. To calculate Co(er) for any value of VDS less than V(BR)DSS, use this equation: Co(er) = -1.33E-7/VDS^2 + 3.06E-8/VDS + 8.83E-11. 6 RG is external gate resistance, not including internal gate resistance or gate driver impedance.
