The STP4NK80Z requires a 10 V gate drive for the specified minimum on-resistance; the gate threshold voltage is 4.5 V maximum at 50 µA drain current, so a standard 12 V gate-drive rail from a PWM controller or driver IC is sufficient. Total gate charge is 22.5 nC at 10 V, which keeps the driver's switching loss manageable in the 50–150 kHz range typical of flyback and forward converters. Input capacitance measures 575 pF at 25 V drain-source, a figure that influences the driver's peak current requirement during turn-on and turn-off transitions. ## Temperature rating and environment The 80 W power dissipation at the case assumes proper heatsinking through the TO-220 tab — in practice, derating follows the thermal resistance curve above 25°C case temperature. The ±30 V maximum gate-source rating provides margin against gate-drive overshoot in noisy switching layouts.","metaTitle":"STP4NK80Z N-Channel MOSFET, 800V, 3A, SuperMESH™","metaDescription":"STP4NK80Z N-channel 800V 3A MOSFET in TO-220, SuperMESH™ series, active production.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","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":"Active","lifecycle_stage":"eol_hot","Vgs(th) (Max) @ Id":"4.5V @ 50µA","Base Product Number":"STP4NK80","Operating Temperature":"-55°C~150°C(TJ)","Rds On (Max) @ Id, Vgs":"3.5Ohm @ 1.5A, 10V","Power Dissipation (Max)":"80W (Tc)","Supplier Device Package":"TO-220","Gate Charge (Qg) (Max) @ Vgs":"22.5 nC @ 10 V","Drain to Source Voltage (Vdss)":"800 V","Input Capacitance (Ciss) (Max) @ Vds":"575 pF @ 25 V","Drive Voltage (Max Rds On, Min Rds On)":"10V","Current - Continuous Drain (Id) @ 25°C":"3A (Tc)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.9400","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/cd0f9ef57e009e806bd5653b1fccd4f3.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the closest pin-compatible alternative to STP4NK80Z?","answer":"STP4NK80Z shares the TO-220 footprint and SuperMESH™ technology with other members of the STP4NK80 family, such as STP4NK80FP (fully isolated TO-220FP package).
