60 V, 80 A P-channel switch — the load-budget anchor
The Infineon SPP80P06PHXKSA1 is a P-Channel SIPMOS MOSFET rated for a continuous drain current of 80 A at 25°C case temperature, with a 60 V drain-to-source breakdown voltage. On-resistance is specified at 23 mOhm maximum at a 64 A drain current and 10 V gate drive. This combination puts it in the high-current P-channel tier—useful for load switches, battery protection, and motor-drive high-side applications where an N-channel would need a charge-pump gate driver.
Thermal headroom and junction rating
That 175°C max junction temperature is the ceiling for sustained operation in high-ambient enclosures—think industrial motor drives or power supplies where the heatsink is shared. The wide temperature floor also suits cold-start environments like outdoor telecom cabinets.
Gate charge and switching profile
Total gate charge is 173 nC at 10 V, with an input capacitance of 5033 pF at 25 V drain-source. This is a moderate drive load for a P-channel of this current rating. A gate driver that can source and sink a few amperes peak will keep switching losses in check at frequencies up to several tens of kHz. The 10 V drive voltage is the recommended gate drive for achieving the rated Rds(on).
Through-hole package — PG-TO220-3-1
The part comes in a standard TO-220-3 through-hole package, Infineon's PG-TO220-3-1 variant. The through-hole format simplifies heatsinking with a single screw or clip, and it's straightforward to hand-assemble or rework. No special soldering profile needed; standard wave or hand-solder works.
Sourcing and lifecycle status
It is ROHS3 compliant.
