Gate charge of 45 nC at 10 V sets the switching loss budget. The TO-220 package is through-hole, which means the leads go into plated holes on the board. Rework is straightforward with a soldering iron — no hot-air profile needed — but the tab is electrically connected to the drain, so the heatsink must be electrically isolated or the system must tolerate the drain potential on the heatsink. The base product number STP31 covers the family; the suffix N65M5 identifies this specific 650 V MDmesh V variant.","metaTitle":"STP31N65M5 N-Channel MOSFET, 650 V, 22 A, TO-220","metaDescription":"STMicroelectronics STP31N65M5 N-channel 650 V 22 A MOSFET in TO-220 package. 148 mOhm Rds(on) at 10 V, 45 nC gate charge.","metaKeywords":null},"attributes":{"series":"MDmesh™ V","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","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","Product Status":"Active","lifecycle_stage":"eol_hot","Vgs(th) (Max) @ Id":"5V @ 250µA","Base Product Number":"STP31","Operating Temperature":"150°C(TJ)","Rds On (Max) @ Id, Vgs":"148mOhm @ 11A, 10V","Power Dissipation (Max)":"150W (Tc)","Supplier Device Package":"TO-220","Gate Charge (Qg) (Max) @ Vgs":"45 nC @ 10 V","Drain to Source Voltage (Vdss)":"650 V","Input Capacitance (Ciss) (Max) @ Vds":"816 pF @ 100 V","Drive Voltage (Max Rds On, Min Rds On)":"10V","Current - Continuous Drain (Id) @ 25°C":"22A (Tc)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$4.2800","priceTiers":[{"qty":1,"price":"$4.28000","currency":"USD"},{"qty":10,"price":"$3.84400","currency":"USD"},{"qty":100,"price":"$3.14930","currency":"USD"},{"qty":500,"price":"$2.68092","currency":"USD"},{"qty":1000,"price":"$2.66630","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/e360865fdaf5fa7433f614e6ca28d88d.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STP31N65M5/alternatives.json"},"ai":{"faq":[{"question":"What is the Rds(on) of STP31N65M5?","answer":"This is the value used for conduction loss calculations at rated current."},{"question":"Can STP31N65M5 replace STP30N65M5?","answer":"Both are 650 V N-channel MOSFETs in TO-220 from the MDmesh family, but the STP31N65M5 has a lower Rds(on) (148 mOhm vs the STP30N65M5's typical 190 mOhm) and higher current rating (22 A vs 18 A).
