The 40 W package limit from the TO-220FP means a heatsink is needed for continuous operation above a few amps. ## TO-220 Full Pack — the isolated tab that saves an insulator The TO-220-3 Full Pack (TO-220FP) is the fully isolated variant of the standard TO-220. The metal tab is encapsulated in the moulding compound, so the mounting surface is electrically isolated from the drain. The trade-off is higher thermal resistance junction-to-case compared to a standard TO-220, which is reflected in the 40 W dissipation ceiling. The through-hole mounting suits point-of-load stages on single-sided boards or where vibration resistance matters more than board density. There is no last-time-buy notification or obsolescence risk on the near horizon. For a BOM that already qualifies this part, no urgency to re-spin or pre-buy exists — though stocking the line against a long forecast is always prudent for any discrete power device with a single-source wafer process.","metaTitle":"STF45N65M5 N-Channel MOSFET, 650 V, 35 A, TO-220FP","metaDescription":"STF45N65M5 N-channel 650 V 35 A MOSFET from STMicroelectronics MDmesh V series. 78 mOhm Rds(on) at 10 V, 91 nC gate charge.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"Mfr":"STMicroelectronics","Series":"MDmesh™ V","Package":"Tube","FET Type":"N-Channel","Vgs (Max)":"±25V","Technology":"MOSFET (Metal Oxide)","FET Feature":"-","Mounting Type":"Through Hole","Package / Case":"TO-220-3 Full Pack","Product Status":"Active","lifecycle_stage":"eol_hot","Vgs(th) (Max) @ Id":"5V @ 250µA","Base Product Number":"STF45","Operating Temperature":"150°C(TJ)","Rds On (Max) @ Id, Vgs":"78mOhm @ 19.5A, 10V","Power Dissipation (Max)":"40W (Tc)","Supplier Device Package":"TO-220FP","Gate Charge (Qg) (Max) @ Vgs":"91 nC @ 10 V","Drain to Source Voltage (Vdss)":"650 V","Input Capacitance (Ciss) (Max) @ Vds":"3375 pF @ 100 V","Drive Voltage (Max Rds On, Min Rds On)":"10V","Current - Continuous Drain (Id) @ 25°C":"35A (Tc)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$7.8500","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/2f8e8c9842713338da1788eadcea58f4.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STF45N65M5/alternatives.json"},"ai":{"faq":[{"question":"Can I replace STF45N65M5 with STF45N65M2?","answer":"The evidence does not carry parametric data for the STF45N65M2, so a direct comparison of Rds(on), gate charge, or switching performance cannot be made from this record.
