The STP270N4F3 is listed as obsolete. Any replacement candidate must match the 40 V / 120 A / 2.9 mOhm envelope and the TO-220 footprint — a direct pin-compatible substitute from the same STripFET™ III family is not documented, so a parametric cross-search is the practical route. The 40 V Vdss sets the maximum off-state voltage — a replacement must not be lower. The 120 A continuous drain rating at 25°C case temperature is the thermal limit; actual current in a design depends on heatsinking and ambient, but the replacement should match or exceed this figure.","metaTitle":"STP270N4F3 STripFET™ III N-Channel MOSFET, 40 V, 120 A","metaDescription":"STP270N4F3 N-channel MOSFET from STMicroelectronics, 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™ III","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":"$1.8800","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/eab272c39dd3de689999e71cfeb09fb3.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STP270N4F3/alternatives.json"},"ai":{"faq":[{"question":"Where can I buy STP270N4F3?","answer":"The STP270N4F3 is obsolete but can be sourced through independent distribution."},{"question":"Is STP270N4F3 obsolete?","answer":"Yes, the STP270N4F3 is listed as obsolete.
