The exposed tab is the drain, so the PCB pad area under the tab sets the junction-to-ambient thermal resistance; a 1-inch² copper pour on a 2-oz board typically keeps the tab temperature within 30 °C of ambient at the rated 125 W dissipation (Tc). A gate driver sourcing 1 A charges the gate in roughly 80 ns, but the practical switching edge is slower because the Miller plateau extends the rise time. Input capacitance (Ciss) is 1760 pF at 25 V drain-source. This loads the driver output at the start of the switching transition; a 10 Ω series gate resistor slows the edge enough to control ringing without extending the switching loss significantly. ## Temperature grade and operating margin The junction temperature range is -55 °C to 175 °C — the full industrial temperature band plus margin for self-heating. At 40 A continuous, the junction rises above the case temperature by the product of Rds(on) and the square of the current, times the thermal resistance junction-to-case. At 125 °C junction, Rds(on) roughly doubles from the 25 °C value, so the available continuous current derates.","metaTitle":"STD45NF75T4 N-Channel MOSFET, 75 V, 40 A, DPAK","metaDescription":"STD45NF75T4 N-Channel MOSFET from STMicroelectronics, STripFET™ II series. 75 V drain-source, 40 A continuous, 24 mOhm Rds(on).","metaKeywords":null},"attributes":{"series":"STripFET™ II","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"Mfr":"STMicroelectronics","Series":"STripFET™ II","Package":"Tape & Reel (TR); Cut Tape (CT)","FET Type":"N-Channel","Vgs (Max)":"±20V","Technology":"MOSFET (Metal Oxide)","FET Feature":"-","Mounting Type":"Surface Mount","Package / Case":"TO-252-3, DPak (2 Leads + Tab), SC-63","Product Status":"Active","lifecycle_stage":"eol_hot","Vgs(th) (Max) @ Id":"4V @ 250µA","Base Product Number":"STD45","Operating Temperature":"-55°C~175°C(TJ)","Rds On (Max) @ Id, Vgs":"24mOhm @ 20A, 10V","Power Dissipation (Max)":"125W (Tc)","Supplier Device Package":"DPAK","Gate Charge (Qg) (Max) @ Vgs":"80 nC @ 10 V","Drain to Source Voltage (Vdss)":"75 V","Input Capacitance (Ciss) (Max) @ Vds":"1760 pF @ 25 V","Drive Voltage (Max Rds On, Min Rds On)":"10V","Current - Continuous Drain (Id) @ 25°C":"40A (Tc)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.9700","priceTiers":[{"qty":1,"price":"$1.97000","currency":"USD"},{"qty":10,"price":"$1.76900","currency":"USD"},{"qty":100,"price":"$1.42200","currency":"USD"},{"qty":500,"price":"$1.16828","currency":"USD"},{"qty":1000,"price":"$1.10215","currency":"USD"},{"qty":2500,"price":"$1.10215","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/bc9e2e0df9d456ed904375e669f0d26d.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STD45NF75T4/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/STD45NF75T4","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/STD45NF75T4 when reusing this data.
