The TO-220 through-hole package handles 70 W dissipation with an adequate heatsink — the junction temperature rating goes to 175 °C, so the thermal design needs proper derating above 85 °C ambient. ## Obsolete — sourcing path for production fills For BOM lines that still call out this exact part, the available channel is independent distribution — new-old-stock or surplus lots sourced against an RFQ. A buyer filling a production gap should verify date-code consistency and request a C of C, especially if the lot is several years past the last-time-buy window. The part is not in active factory production, so the procurement decision is about qualifying surplus inventory, not placing a factory order. ## Package and mounting — through-hole TO-220 The tab is electrically live — an insulating pad and washer are needed if the heatsink is grounded. The package ships in Tube form, not tape-and-reel, which matters for automated assembly line feeding.","metaTitle":"STP85N3LH5 STripFET V N-Channel MOSFET, 30 V, 80 A, TO-220","metaDescription":"STP85N3LH5 N-channel MOSFET from STMicroelectronics STripFET V series. 30 V Vdss, 80 A Id, 5.4 mOhm Rds(on) at 10 V.
