150 V, 35 A N-channel — the conduction loss floor
The IRFB4615PBF: The 39 mOhm maximum on-resistance at 21 A, 10 V gate drive sets the conduction loss floor.
Gate drive budget and switching loss
Total gate charge is 26 nC at 10 V Vgs.
Thermal headroom in the TO-220AB
Maximum power dissipation is 144 W at case temperature, derated to zero at 175 °C junction.
