Its 75 V drain-to-source breakdown (Vdss) gives headroom on a 48 V bus, and the 78 A continuous drain rating at 25 °C case temperature handles motor-drive inrush and power-supply primary-side loads without derating anxiety. Gate charge is 76 nC at 10 V, a moderate figure for a 78 A device. That means a standard gate-driver IC or a simple totem-pole pair can switch it at tens of kHz without excessive drive losses. The 4 V gate threshold maximum at 250 µA drain current confirms this is a 10 V-logic device — do not expect full enhancement at 5 V gate drive; plan for a 10 V rail or a dedicated bootstrap supply. If this part is on your active BOM, you are already sourcing from the surplus and independent-distribution channel — and that is where we come in. No stock promises on the page; the RFQ gets you the real picture. ## Through-hole TO-220 — mounting and thermal reality The STP75N75F4 comes in a standard TO-220-3 through-hole package, also listed as supplier device package TO-220. That means a 0.100-inch pitch, a metal tab for heatsink mounting, and a screw hole for a TO-220 clip or bolt-down heatsink. The 150 W power dissipation is rated at case temperature (Tc), not ambient — you need a heatsink to get anywhere near that number. Without one, junction-to-ambient thermal resistance for TO-220 typically runs 60–80 °C/W, so at 3 W dissipation the junction hits 180–240 °C above ambient. Plan the thermal interface: a greased mica pad or silicone pad, a clip or screw, and forced air if the dissipation is continuous. ## Temperature range and what it buys you That extra margin matters if the part sits near a hot heatsink in a sealed enclosure or sees repetitive avalanche pulses that spike the junction above 150 °C. The storage temperature range is the same, so no special handling beyond standard ESD precautions.","metaTitle":"STP75N75F4 N-Channel MOSFET, 75V 78A TO-220, Obsolete","metaDescription":"STP75N75F4 DeepGATE STripFET N-Channel MOSFET: 75V Vdss, 78A Id, 11mOhm Rds(on).

For a pin-compatible replacement in the same TO-220 footprint, look for N-channel MOSFETs with similar ratings: 75 V or higher Vdss, 78 A or higher Id, and 11 mΩ or lower Rds(on) at 10 V gate drive.
