The STU13N60M2 is an N-channel MOSFET in a TO-251-3 (IPAK) through-hole package.
Gate charge totals 17 nC at 10 V. Input capacitance is 580 pF at 100 V drain-source, which keeps the Miller plateau short and the switching energy per cycle low — useful for pushing the switching frequency above 100 kHz in a QR flyback or LLC converter.
