60 V, 172 A N-channel in TO-247 — what it delivers
The Infineon IRFP7537PBF is a 60 V N-channel MOSFET from the HEXFET® and StrongIRFET™ series, rated for 172 A continuous drain current at 25 °C case temperature. The 3.3 mOhm maximum on-resistance at 100 A and 10 V gate drive puts it in the low-Rds(on) tier for a through-hole TO-247 part, which directly reduces conduction losses in high-current switching stages like motor drives, battery chargers, and DC-DC converters. The 210 nC gate charge at 10 V means the gate driver needs enough peak current to charge that capacitance quickly — factor that into driver selection and switching loss calculations. The 230 W power dissipation rating sets the thermal budget: a heatsink sized for the junction-to-case thermal path is mandatory to stay inside the 175 °C maximum junction temperature.
Mounting and rework — TO-247 with through-hole leads
Through-hole TO-247-3 package, three leads. The large tab and screw hole are the primary heat path — use a thermal interface material rated for the dissipation.
Lifecycle and sourcing — active, no LTB pressure
The IRFP7537PBF carries an Active lifecycle status per the manufacturer. It is suitable for new production builds and ongoing BOM maintenance without obsolescence risk.
