Gate charge of 62 nC at 10 V means the gate driver sees a moderate capacitive load; a 1 A driver can switch it in roughly 60 ns, making it usable in 100–200 kHz converters if the layout keeps the gate loop tight. That extra 25°C headroom matters for under-hood automotive or industrial enclosures where ambient hits 105°C and self-heating piles on. STMicroelectronics lists the STD155N3H6 as obsolete. No last-time-buy window or official successor is recorded in the lifecycle data. Every lot we source gets date-code and marking verification against ST's known laser-etch font and DPAK package tooling; the laser etch on a genuine part traces cleanly to ST's plant and week code. Because the part is obsolete, a buyer should qualify a drop-in alternative if the design allows. The 30 V, 3 mΩ, DPAK footprint is a common sweet spot — several current-production ST parts and competitors' N-channel MOSFETs share the same pinout and similar gate charge.","metaTitle":"STD155N3H6 N-Channel MOSFET, 30 V, 3 mΩ, DPAK","metaDescription":"STD155N3H6 N-Channel MOSFET from STMicroelectronics DeepGATE™ STripFET™ VI series. 30 V Vdss, 3 mΩ Rds(on) at 10 V, 80 A continuous drain.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Discrete Semiconductors"],"specifications":{"Mfr":"STMicroelectronics","Series":"DeepGATE™, STripFET™ VI","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":"Obsolete","lifecycle_stage":"eol_hot","Vgs(th) (Max) @ Id":"4V @ 250µA","Base Product Number":"STD15","Operating Temperature":"-55°C~175°C(TJ)","Rds On (Max) @ Id, Vgs":"3mOhm @ 40A, 10V","Power Dissipation (Max)":"110W (Tc)","Supplier Device Package":"DPAK","Gate Charge (Qg) (Max) @ Vgs":"62 nC @ 10 V","Drain to Source Voltage (Vdss)":"30 V","Input Capacitance (Ciss) (Max) @ Vds":"3650 pF @ 25 V","Drive Voltage (Max Rds On, Min Rds On)":"10V","Current - Continuous Drain (Id) @ 25°C":"80A (Tc)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.0600","priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STD155N3H6/alternatives.json"},"ai":{"faq":[{"question":"Is STD155N3H6 obsolete?","answer":"Yes, STMicroelectronics has marked the STD155N3H6 as obsolete.
