The STP80NF06: The through-hole TO-220 package allows direct mounting to a heatsink for thermal management in industrial and automotive auxiliary loads.
Key ratings that drive the BOM decision
The 60 V Vdss gives headroom on a 48 V or 24 V bus but is tight for 48 V telecom with transients — factor in derating. The 80 A continuous rating is package-limited; real-world current depends on heatsinking and ambient. The 8 mOhm Rds(on) at 10 V gate drive means the gate must be driven to 10 V to achieve the rated on-resistance — a 5 V logic gate drive will not fully enhance this device, so budget a gate driver or a 10 V rail. The maximum junction temperature is 175°C, and the package is rated for 300 W dissipation at the case.
