At 17 A the conduction loss is I²R = 17² × 0.165 ≈ 48 W under the worst-case Rds(on) — the 110 W power-dissipation rating at the case gives headroom, but the junction-to-case thermal path in the DPAK requires a copper pour on the drain tab to keep Tj below 175 °C. Gate charge is 29.5 nC at 10 V, which means a gate-driver sourcing 1 A can charge the gate in roughly 30 ns — fast enough for a 100 kHz switching regulator without excessive cross-conduction. ## AEC-Q101 — the automotive gate The Automotive grade and AEC-Q101 qualification are the defining differentiators. This part is not just a general-purpose 250 V MOSFET in a DPAK — it has been through the AEC-Q101 stress tests (high-temperature reverse bias, temperature cycling, humidity) that an under-hood or chassis-domain ECU requires. Lifecycle status is Active per STMicroelectronics.","metaTitle":"STD18NF25 N-Channel MOSFET, 250 V 17 A, AEC-Q101, DPAK","metaDescription":"STD18NF25 N-channel 250 V 17 A MOSFET, STripFET II, 165 mOhm Rds(on), AEC-Q101 automotive grade.","metaKeywords":null},"attributes":{"series":"STripFET™ II","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"Mfr":"STMicroelectronics","Grade":"Automotive","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","Qualification":"AEC-Q101","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":"STD18","Operating Temperature":"-55°C ~ 175°C (TJ)","Rds On (Max) @ Id, Vgs":"165mOhm @ 8.5A, 10V","Power Dissipation (Max)":"110W (Tc)","Supplier Device Package":"DPAK","Gate Charge (Qg) (Max) @ Vgs":"29.5 nC @ 10 V","Drain to Source Voltage (Vdss)":"250 V","Input Capacitance (Ciss) (Max) @ Vds":"1000 pF @ 25 V","Drive Voltage (Max Rds On, Min Rds On)":"10V","Current - Continuous Drain (Id) @ 25°C":"17A (Tc)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.0800","priceTiers":[{"qty":1,"price":"$2.08000","currency":"USD"},{"qty":10,"price":"$1.72800","currency":"USD"},{"qty":100,"price":"$1.37510","currency":"USD"},{"qty":500,"price":"$1.16356","currency":"USD"},{"qty":1000,"price":"$0.98725","currency":"USD"},{"qty":2500,"price":"$0.93789","currency":"USD"},{"qty":5000,"price":"$0.90263","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/9039821023ddd272d76dba42d903a64b.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STD18NF25/alternatives.json"},"ai":{"faq":[{"question":"How can I order STD18NF25 or check current pricing?","answer":"The STD18NF25 is an active-production part.
