The STP270N04 is marked Obsolete by STMicroelectronics. ## Package and mounting — TO-220 through-hole The tab is electrically connected to the drain, so an insulating pad and thermal compound are needed if the heatsink is grounded.","metaTitle":"STP270N04 STripFET N-Channel MOSFET, 40 V, 120 A, TO-220","metaDescription":"STP270N04 N-channel MOSFET, 40 V Vdss, 120 A Id, 2.9 mOhm Rds(on) at 10 V.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Discrete Semiconductors"],"specifications":{"Mfr":"STMicroelectronics","Series":"STripFET™","Package":"Tube","FET Type":"N-Channel","Vgs (Max)":"±20V","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":"4V @ 250µA","Base Product Number":"STP270","Operating Temperature":"-55°C~175°C(TJ)","Rds On (Max) @ Id, Vgs":"2.9mOhm @ 80A, 10V","Power Dissipation (Max)":"330W (Tc)","Supplier Device Package":"TO-220","Gate Charge (Qg) (Max) @ Vgs":"150 nC @ 10 V","Drain to Source Voltage (Vdss)":"40 V","Input Capacitance (Ciss) (Max) @ Vds":"7400 pF @ 25 V","Drive Voltage (Max Rds On, Min Rds On)":"10V","Current - Continuous Drain (Id) @ 25°C":"120A (Tc)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/60b98510739376d91e178b7f0e39061e.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STP270N04/alternatives.json"},"ai":{"faq":[{"question":"What is the replacement for STP270N04?","answer":"A pin-compatible substitute should match the 40 V Vdss, 120 A Id rating, and TO-220 package, with similar or lower Rds(on) and gate charge.
