The through-hole TO-247-3 package (PG-TO247-3) is designed for screw-mount or clip-mount to a heatsink; the exposed metal tab is the drain. Mounting torque should follow the manufacturer's recommendation to avoid package stress. ## Active lifecycle — no obsolescence concern ROHS3 compliant. For new designs or spares, this part is a safe choice without last-time-buy risk.","metaTitle":"Infineon SPW55N80C3FKSA1 CoolMOS C3 N-Ch MOSFET, 800V 54.9A","metaDescription":"Infineon SPW55N80C3FKSA1 CoolMOS C3 N-channel MOSFET, 800V Vdss, 54.9A Id, 85mOhm Rds(on).
