The full-pack moulding isolates the tab electrically, so the heatsink can be grounded without an insulating washer — a practical advantage in offline flyback converters, PFC stages, and auxiliary power supplies where the drain sits at high voltage. ## Switching loss budget: low gate charge and capacitance On-resistance is 1.75 Ohm max at 2 A, 10 V. For a BOM line in a power supply design, this part is a clean fit for new production — no LTB risk, no compliance gap.","metaTitle":"STF5N80K5 MOSFET N-CH 800V 4A TO220FP MDmesh™","metaDescription":"STF5N80K5 N-channel 800V 4A MOSFET in TO-220FP. 1.75 Ohm Rds(on), 5 nC gate charge.
