The 950 V rating provides a healthy margin above the typical 400 V DC bus in single-phase offline designs, reducing avalanche stress during line surges. On-resistance is specified at 3.5 Ohm maximum with 10 V gate drive at 2 A drain current, which keeps conduction losses manageable for the 4 A current envelope in a TO-220 package dissipating up to 90 W case-limited. Gate charge is 19 nC at 10 V, a moderate figure that allows direct drive from a PWM controller without a dedicated gate driver in lower-frequency designs, though a driver is recommended above 100 kHz to minimize switching losses. No last-time-buy window or successor part is recorded in the official lifecycle data. For existing BOM lines, procurement must turn to independent distribution channels for remaining inventory or qualified surplus stock. Buyers should expect to supply a target quantity and date code preference when requesting a quote. The TO-220-3 through-hole package is designed for heatsink mounting via the metal tab; thermal resistance to case is the limiting factor for power dissipation, rated at 90 W at 25°C case temperature. The threshold voltage is specified at 5 V maximum at 100 µA drain current, ensuring the device is fully enhanced with standard 10 V logic.","metaTitle":"STP5N95K3 N-Channel MOSFET, 950 V, 4 A, TO-220","metaDescription":"STP5N95K3 N-channel MOSFET from STMicroelectronics SuperMESH3 series: 950 V drain-source, 4 A continuous drain, 3.5 Ohm Rds(on), TO-220-3.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Discrete Semiconductors"],"specifications":{"Mfr":"STMicroelectronics","Series":"SuperMESH3™","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":"5V @ 100µA","Base Product Number":"STP5N","Operating Temperature":"-55°C ~ 150°C (TJ)","Rds On (Max) @ Id, Vgs":"3.5Ohm @ 2A, 10V","Power Dissipation (Max)":"90W (Tc)","Supplier Device Package":"TO-220","Gate Charge (Qg) (Max) @ Vgs":"19 nC @ 10 V","Drain to Source Voltage (Vdss)":"950 V","Input Capacitance (Ciss) (Max) @ Vds":"460 pF @ 25 V","Drive Voltage (Max Rds On, Min Rds On)":"10V","Current - Continuous Drain (Id) @ 25°C":"4A (Tc)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$5.3800","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/c78a655001ee852717e11e0cd564a55a.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is STP5N95K3 obsolete?","answer":"Yes, the STP5N95K3 is listed as obsolete.
