650 V N-channel in a full-pack TO-220
The STFU13N65M2 is an N-channel 650 V 10 A MOSFET in the TO-220FP full-pack package.
Maximum on-resistance is 430 mOhm at 5 A drain current with 10 V gate drive. That figure sets the conduction loss floor for a given RMS current in a flyback primary or PFC boost stage — at 2 A RMS the dissipation is under 2 W, leaving headroom inside the 25 W power dissipation limit at the case. Gate charge is 17 nC at 10 V. Input capacitance is 590 pF at 100 V drain bias.
