30 V, 3.4 mOhm — the conduction-loss anchor
The IPP034N03LG: The continuous drain current is rated at 80 A at a 25°C case temperature, though in practice you derate that figure for your actual operating junction temperature and heatsinking.
Gate drive and switching budget
Total gate charge is 51 nC at 10 V drive. Input capacitance (Ciss) is 5300 pF at 15 V drain-source.
Package and thermal path
Housed in a standard TO-220-3 through-hole package (Infineon's variant PG-TO220-3-1), the part is intended for heatsink mounting via the metal tab. Maximum power dissipation is 94 W at the case temperature, but the actual limit depends on the heatsink's thermal resistance and ambient conditions.
Lifecycle and compliance
The series is OptiMOS™ 3, a mature and widely used generation.
