These numbers tell the gate-drive designer what the driver must supply per switching cycle and how fast the device can turn on and off. The ±25 V absolute maximum on the gate leaves headroom for ringing, but a gate clamp or zener is still prudent in noisy layouts. STMicroelectronics lists the STF12NM50N as obsolete. No official successor part number appears in the record. For new production, a pin-compatible MDmesh II or MDmesh V device with similar voltage and current class would need to be evaluated — the TO-220FP footprint is common across the family, but gate charge and Rds(on) differ between generations. Date-code spread and packaging condition (sealed reels or tube-cut) vary by lot; we inspect each procurement lot for original ST branding and traceability.","metaTitle":"STF12NM50N N-Channel MOSFET, 500V, 11A, TO-220FP","metaDescription":"STF12NM50N MDmesh II N-channel MOSFET, 500 Vdss, 11 A continuous drain, 380 mOhm Rds(on) at 10V.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Discrete Semiconductors"],"specifications":{"Mfr":"STMicroelectronics","Series":"MDmesh™ II","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":"Obsolete","lifecycle_stage":"eol_hot","Vgs(th) (Max) @ Id":"4V @ 250µA","Base Product Number":"STF12","Operating Temperature":"150°C (TJ)","Rds On (Max) @ Id, Vgs":"380mOhm @ 5.5A, 10V","Power Dissipation (Max)":"25W (Tc)","Supplier Device Package":"TO-220FP","Gate Charge (Qg) (Max) @ Vgs":"30 nC @ 10 V","Drain to Source Voltage (Vdss)":"500 V","Input Capacitance (Ciss) (Max) @ Vds":"940 pF @ 50 V","Drive Voltage (Max Rds On, Min Rds On)":"10V","Current - Continuous Drain (Id) @ 25°C":"11A (Tc)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$4.4200","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/7a8dc1b9175b945619b56d1d85bb66d3.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Where can I buy STF12NM50N?","answer":"Submit an RFQ for current availability, pricing, and date-code information.
