100 V, 42 A N-channel HEXFET in a TO-247AC can
Housed in a TO-247AC through-hole package, it carries a 36 mOhm maximum on-resistance when driven with 10 V on the gate — the drive voltage for the lowest Rds(on). The 110 nC gate charge at 10 V gives a rough idea of the switching energy; a gate driver that can source and sink a couple of amps will keep transition times short in a hard-switched converter.
The 160 W maximum power dissipation is specified at a 25 °C case temperature. The junction temperature range of -55 to 175 °C covers industrial environments.

For BOM planning, that means no urgent replacement search needed.
