Any replacement evaluation should start with the same SuperMESH family at the same voltage and current class, but pin compatibility and gate-drive requirements must be verified against the target circuit. ## Key ratings for the power-stage decision The 700 V Vdss gives headroom for universal-input off-line converters (up to 400 V DC bus) with derating for leakage inductance spikes. The 8.6 A continuous rating at 25°C case temperature derates with case temperature — the actual current limit at elevated junction temperature is lower, so the thermal design must budget for the 150 W maximum power dissipation. Gate charge of 90 nC at 10 V is moderate; the driver must supply that charge per switching cycle, which influences gate-drive power and switching speed. Input capacitance of 2000 pF at 25 V drain-source is a typical figure for this die size and does not by itself limit switching frequency, but the combination of Qg and Ciss sets the driver's peak current requirement.","metaTitle":"STP10NK70Z N-Channel MOSFET, 700 V, 8.6 A, TO-220","metaDescription":"STP10NK70Z N-Channel MOSFET from STMicroelectronics SuperMESH series, 700 V Vdss, 8.6 A Id, 850 mOhm Rds(on), TO-220 package.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","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":"Obsolete","lifecycle_stage":"eol_hot","Vgs(th) (Max) @ Id":"4.5V @ 100µA","Base Product Number":"STP10","Operating Temperature":"-55°C ~ 150°C (TJ)","Rds On (Max) @ Id, Vgs":"850mOhm @ 4.5A, 10V","Power Dissipation (Max)":"150W (Tc)","Supplier Device Package":"TO-220","Gate Charge (Qg) (Max) @ Vgs":"90 nC @ 10 V","Drain to Source Voltage (Vdss)":"700 V","Input Capacitance (Ciss) (Max) @ Vds":"2000 pF @ 25 V","Drive Voltage (Max Rds On, Min Rds On)":"10V","Current - Continuous Drain (Id) @ 25°C":"8.6A (Tc)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.2500","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/9c7678fd10253f77e9d598c4ac305e22.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STP10NK70Z/alternatives.json"},"ai":{"faq":[{"question":"What is the replacement for STP10NK70Z?","answer":"A replacement should be selected from the same SuperMESH family at 700 V and 8.6 A class, but pin compatibility, gate-drive voltage, and Rds(on) must be verified against the specific circuit.
