Best Replacement for a 45n20B MOSFET Recommendations

[kds9591]

This N channel MOSFET has been discontinued by Fairchild. TO-220 case


Some of the specs are:

Drain-Source Breakdown Voltage: 200 V

Continuous Drain Current: 35 A

Power Dissipation: 176 W

Resistance Drain-Source RDS (on): 0.065 Ohms

Gate-Source Breakdown Voltage: +/- 30 V

Forward Transconductance gFS (Max / Min): 36 S

2 that I crossed ref. that should work are:


Fairchild

FDP52N20

FDP61N20

Perry, what substitute do you use?
