This 'FREDFET' version has a drain-source (body) diode that has been optimized for

recovery, and high recovery dv/dt capability. Low gate charge, high gain, and a greatly

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.
