100 V, 8.2 mΩ — the sweet spot for 48 V and secondary-side switching
The Infineon IPP082N10NF2SAKMA1 is an N-channel MOSFET from the StrongIRFET™ 2 family, built on a trench technology rated for 100 V drain-source. The headline on-resistance is 8.2 mΩ at 10 V gate drive, which puts it in the right bracket for 48 V bus converters, motor-drive bridges, and secondary-side synchronous rectification where conduction loss matters. The package is a standard PG-TO220-3 through-hole — easy to heatsink, common footprint, rugged for industrial assembly. Continuous drain current is rated 15 A at ambient and 77 A at case temperature (Tc), so thermal management is the real limiter; with a decent heatsink the part can handle serious current.
Gate drive and switching — what the numbers mean for your design
The drive voltage range is 6 V to 10 V for achieving the rated Rds(on). At 6 V the on-resistance will be higher than the 8.2 mΩ headline, so check the typical curve if you're running from a 5 V logic gate driver. Gate charge is 42 nC at 10 V — moderate for a 100 V device in this current class; a standard totem-pole driver handles it fine, but don't undersize the gate drive supply if switching above 100 kHz. Input capacitance (Ciss) is 2000 pF at 50 V drain bias, which is manageable and keeps the gate drive losses reasonable.
Temperature range and package — tough enough for industrial and automotive bays
Operating junction temperature spans -55°C to 175°C, which covers under-hood automotive, industrial motor drives, and outdoor telecom enclosures. The PG-TO220-3 package is through-hole, so it's not for dense SMD layouts, but it's a proven workhorse for power stages where thermal vias and heatsink mounting are standard. Power dissipation is rated 3.8 W at ambient and 100 W at case temperature — the case rating is what you design to with a proper heatsink.
Lifecycle and sourcing — active, no obsolescence worry
This part is listed as Active (current production) and ROHS3 compliant. Infineon's StrongIRFET™ 2 series is a mature, widely used trench MOSFET line, so supply is stable through distribution.
