The 800 V drain-source rating gives you a solid voltage margin above a rectified 230 VAC rail, and the 3 A continuous drain current handles moderate power stages without oversizing the package. The gate charge of 22.5 nC at 10 V keeps switching losses manageable for flyback and forward converters. ## Through-hole TO-251 — rework-friendly, but watch the tab The TO-251 (IPAK) package is a three-lead through-hole with short leads and a metal drain tab that needs a good thermal connection to the board copper. The ±30 V maximum gate-source voltage means the gate driver should never exceed a 10 V drive for minimum Rds(on). ## Temperature range and ruggedness for industrial environments The SuperMESH structure gives good avalanche energy capability. The base product number is STD4NK80, and the -1 suffix indicates the TO-251 package variant — the same die is also available in DPAK (STD4NK80Z) if a surface-mount option is preferred.","metaTitle":"STD4NK80Z-1 N-Channel MOSFET, 800V 3A, TO-251 IPAK","metaDescription":"STD4NK80Z-1 N-Channel MOSFET from STMicroelectronics SuperMESH series: 800V Vdss, 3A Id, 3.5 Ohm Rds(on), TO-251 IPAK through-hole package.","metaKeywords":null},"attributes":{"series":"SuperMESH™","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","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-251-3 Short Leads, IPak, TO-251AA","Product Status":"Active","lifecycle_stage":"eol_hot","Vgs(th) (Max) @ Id":"4.5V @ 50µA","Base Product Number":"STD4NK80","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-251 (IPAK)","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":"$1.9700","priceTiers":[{"qty":1,"price":"$1.97000","currency":"USD"},{"qty":10,"price":"$1.63500","currency":"USD"},{"qty":100,"price":"$1.30120","currency":"USD"},{"qty":500,"price":"$1.10106","currency":"USD"},{"qty":1000,"price":"$0.93423","currency":"USD"},{"qty":2000,"price":"$0.88752","currency":"USD"},{"qty":5000,"price":"$0.85415","currency":"USD"},{"qty":10000,"price":"$0.82588","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/59e9df909a8f742c88030f05b291bce5.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STD4NK80Z-1/alternatives.json"},"ai":{"faq":[{"question":"Is STD4NK80Z-1 active or obsolete?","answer":"It is ROHS3 compliant."},{"question":"What package type is STD4NK80Z-1?","answer":"It comes in a TO-251-3 (IPak) through-hole package, also designated as TO-251AA.
