This is a standard-threshold device (5 V max Vgs(th) at 250 µA), requiring 10 V gate drive for minimum Rds(on). Gate charge is 13 nC at 10 V. The MDmesh™ series uses a vertical multi-drain mesh structure to reduce the specific on-resistance while maintaining high breakdown voltage. This part is a good fit for offline flyback converters, single-switch PFC stages, and auxiliary power supplies where 550 V blocking and 8 A pulsed current cover the primary-side switch. STMicroelectronics lists the STP8NM50FP as Obsolete. For production runs still using this part, the only channel is the surplus and independent distribution market — last-time-buy stock that has already left the factory. ## Gate drive and switching considerations The 13 nC total gate charge means the driver's peak current requirement is modest, but keep the gate loop physically tight to avoid ringing at turn-off. Junction temperature range is -65°C to 150°C.","metaTitle":"STP8NM50FP N-Channel MOSFET 550V 8A TO-220FP MDmesh","metaDescription":"STP8NM50FP N-channel 550V 8A MOSFET in TO-220FP full-pack.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Discrete Semiconductors"],"specifications":{"Mfr":"STMicroelectronics","Series":"MDmesh™","Package":"Tube","FET Type":"N-Channel","Vgs (Max)":"±30V","Technology":"MOSFET (Metal Oxide)","FET Feature":"-","Mounting Type":"Through Hole","Package / Case":"TO-220-3 Full Pack","Product Status":"Obsolete","lifecycle_stage":"eol_hot","Vgs(th) (Max) @ Id":"5V @ 250µA","Base Product Number":"STP8N","Operating Temperature":"-65°C~150°C(TJ)","Rds On (Max) @ Id, Vgs":"800mOhm @ 2.5A, 10V","Power Dissipation (Max)":"25W (Tc)","Supplier Device Package":"TO-220FP","Gate Charge (Qg) (Max) @ Vgs":"13 nC @ 10 V","Drain to Source Voltage (Vdss)":"550 V","Input Capacitance (Ciss) (Max) @ Vds":"415 pF @ 25 V","Drive Voltage (Max Rds On, Min Rds On)":"10V","Current - Continuous Drain (Id) @ 25°C":"8A (Tc)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.6400","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/a9f23e87376f54603da6ff0fb0e553f8.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STP8NM50FP/alternatives.json"},"ai":{"faq":[{"question":"What is the difference between STP8NM50FP and STP8NM60FP?","answer":"The STP8NM60FP is a 600 V rated variant in the same MDmesh™ family and the same TO-220FP package.
