With a typical gate charge of 87 nC at 10 V and an input capacitance of 2620 pF at 25 V drain bias, the STP12NK80Z demands a gate driver capable of sourcing and sinking a few amperes peak if you intend to switch above 50 kHz. The 4.5 V gate threshold at 100 µA is comfortably below the 10 V recommended drive, so standard 10 V–15 V gate-drive rails from a PWM controller or a dedicated driver IC will saturate the channel fully. The ±30 V absolute gate-source rating provides margin against ringing on long gate traces. ## NRND — plan the last-time-buy now For a production BOM that already qualifies this MOSFET, the smart move is to secure the LTB quantity now and qualify a pin-compatible drop-in before the window closes. For new designs, skip this part and look at ST's current SuperMESH or MDmesh generation in the same voltage and current class.","metaTitle":"STP12NK80Z N-Channel MOSFET, 800V, 10.5A, NRND","metaDescription":"STP12NK80Z SuperMESH N-channel MOSFET, 800V drain-source, 10.5A continuous drain, 750mOhm Rds(on).","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"NRND","categoryPath":["Discrete Semiconductors"],"specifications":{"Mfr":"STMicroelectronics","Series":"SuperMESH™","Package":"Tube","FET Type":"N-Channel","Vgs (Max)":"±30V","Technology":"MOSFET (Metal Oxide)","FET Feature":"-","Mounting Type":"Through Hole","Package / Case":"TO-220-3","Product Status":"Not For New Designs","lifecycle_stage":"eol_hot","Vgs(th) (Max) @ Id":"4.5V @ 100µA","Base Product Number":"STP12","Operating Temperature":"-55°C~150°C(TJ)","Rds On (Max) @ Id, Vgs":"750mOhm @ 5.25A, 10V","Power Dissipation (Max)":"190W (Tc)","Supplier Device Package":"TO-220","Gate Charge (Qg) (Max) @ Vgs":"87 nC @ 10 V","Drain to Source Voltage (Vdss)":"800 V","Input Capacitance (Ciss) (Max) @ Vds":"2620 pF @ 25 V","Drive Voltage (Max Rds On, Min Rds On)":"10V","Current - Continuous Drain (Id) @ 25°C":"10.5A (Tc)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$3.6800","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/5db3d8d988d4eae8ae7f0b54c9ea04b8.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is STP12NK80Z obsolete?","answer":"It is not yet fully discontinued, but the manufacturer has flagged it for phase-out.
