N-Channel FREDFET
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.

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. (MIC4452)
