The 80 A continuous drain current is a package-limited rating at case temperature — in a real design, the actual current is derated by the junction-to-case thermal resistance and the ambient conditions. The 3.3 mOhm maximum Rds(on) at 10 V gate drive is the headline figure for conduction loss; at 40 A the dissipation is roughly 5.3 W, which the TO-220 package can handle with adequate heatsinking. The gate charge of 40 nC at 4.5 V is moderate — the driver needs to supply that charge each switching cycle, so at 100 kHz the average gate drive current is about 4 mA, which is within the capability of most MOSFET drivers. ## Lifecycle reality — obsolete, sourced to order For new designs, a pin-compatible alternative from the same or another manufacturer should be evaluated. This is a typical situation for a mature, end-of-life power MOSFET: the buyer should expect to work with a broker or surplus channel for the remaining service life of the product.","metaTitle":"STP150N3LLH6 N-Channel MOSFET, 30 V, 80 A, TO-220, Obsolete","metaDescription":"STP150N3LLH6 N-Channel MOSFET from STMicroelectronics, 30 V drain-source, 80 A continuous, 3.3 mOhm Rds(on) at 10 V.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Discrete Semiconductors"],"specifications":{"Mfr":"STMicroelectronics","Series":"DeepGATE™, STripFET™ VI","Package":"Tube","FET Type":"N-Channel","Vgs (Max)":"±20V","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":"2.5V @ 250µA","Base Product Number":"STP150","Operating Temperature":"-55°C~175°C(TJ)","Rds On (Max) @ Id, Vgs":"3.3mOhm @ 40A, 10V","Power Dissipation (Max)":"110W (Tc)","Supplier Device Package":"TO-220","Gate Charge (Qg) (Max) @ Vgs":"40 nC @ 4.5 V","Drain to Source Voltage (Vdss)":"30 V","Input Capacitance (Ciss) (Max) @ Vds":"4040 pF @ 25 V","Drive Voltage (Max Rds On, Min Rds On)":"4.5V, 10V","Current - Continuous Drain (Id) @ 25°C":"80A (Tc)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$3.0300","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/cc002cbc3d7e5e6b94497c1cba2e1882.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STP150N3LLH6/alternatives.json"},"ai":{"faq":[{"question":"Where can I buy STP150N3LLH6 today?","answer":"The STP150N3LLH6 is obsolete and no longer in production."},{"question":"What is the best replacement for STP150N3LLH6?","answer":"For new designs, look for a low-voltage N-channel MOSFET in a TO-220 package with a 30 V Vdss, 80 A or higher Id rating, and an Rds(on) at or below 3.3 mOhm at 10 V gate drive.
