650 V N-channel — the high-voltage switching workhorse
The STP16NK65Z N-channel MOSFET has 500 mOhm on-resistance at 6.5 A, 10 V drive and 89 nC total gate charge at 10 V.
At 6.5 A continuous, the 500 mOhm Rds(on) dissipates about 21 W — well within the 190 W power-dissipation ceiling, but the TO-220 package needs a heatsink sized for that thermal load at the ambient temperature.
