StrongIRFET™ N-channel — 150 V, 203 A, 2.7 mOhm
The Infineon IRF150P220AKMA1 is a 150 V, 203 A N-channel MOSFET from the StrongIRFET™ series, housed in a TO-247-3 through-hole package. It targets high-current switching applications where conduction loss dominates — motor drives, battery management systems, DC-DC converters, and industrial power supplies. The headline 2.7 mOhm Rds(on) max at 100 A and 10 V gate drive keeps I²R losses low enough that a single TO-247 can handle loads that would otherwise require paralleled smaller devices.
Gate charge and switching budget
The 200 nC gate charge at 10 V and 12000 pF input capacitance at 75 V Vds set the drive requirement.
Thermal and mechanical fit
The TO-247-3 package (PG-TO247-3) is a standard through-hole footprint with a large metal tab for heatsink mounting. The 556 W power dissipation at case temperature tells you this part needs a substantial heatsink and forced airflow if you plan to run anywhere near the 203 A continuous current. The 3.8 W at ambient is the free-air limit — essentially a derating floor.
