Threshold voltage maxes at 4 V with 250 µA of drain current. STMicroelectronics lists the STD20N20T4 as obsolete. No direct pin-compatible replacement is named in the official record. For existing BOMs, the independent distribution channel is the practical source — we can quote available inventory against an RFQ. When qualifying a substitute, look for a 200 V N-channel MOSFET in DPAK with similar gate charge and on-resistance.","metaTitle":"STD20N20T4 N-Channel MOSFET, 200 V, 18 A, DPAK","metaDescription":"STMicroelectronics STD20N20T4 N-channel MOSFET, 200 V Vdss, 18 A Id, 125 mOhm Rds(on), DPAK package.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","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":"Obsolete","lifecycle_stage":"eol_hot","Vgs(th) (Max) @ Id":"4V @ 250µA","Base Product Number":"STD20N","Operating Temperature":"-","Rds On (Max) @ Id, Vgs":"125mOhm @ 10A, 10V","Power Dissipation (Max)":"90W (Tc)","Supplier Device Package":"DPAK","Gate Charge (Qg) (Max) @ Vgs":"39 nC @ 10 V","Drain to Source Voltage (Vdss)":"200 V","Input Capacitance (Ciss) (Max) @ Vds":"940 pF @ 25 V","Drive Voltage (Max Rds On, Min Rds On)":"10V","Current - Continuous Drain (Id) @ 25°C":"18A (Tc)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.3200","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/8922a0fcbad65aef8bf2834edbb19f55.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STD20N20T4/alternatives.json"},"ai":{"faq":[{"question":"What is the best replacement for STD20N20T4?","answer":"No official replacement is listed by STMicroelectronics. A suitable substitute would be a 200 V N-channel MOSFET in DPAK with comparable Rds(on) and gate charge.
