The STPLED524 is specified for a 10 V gate drive for rated Rds(on); the threshold voltage is 4.5 V maximum at 50 µA drain current, so a 5 V logic-level gate signal may not fully enhance the channel. A gate driver that swings to 10 V is recommended to achieve the 2.6 Ohm on-resistance. The 12 nC gate charge is low — a typical MCU GPIO driving through a small NPN transistor pair can switch it at tens of kHz without excessive drive loss. Input capacitance is 340 pF at 100 V Vds, which keeps the switching node capacitance low and helps reduce turn-on losses in a hard-switched converter. ## Package and mounting — TO-220-3 through-hole The supplier device package is TO-220. The tab is electrically connected to the drain — account for this in the PCB layout: either isolate the heatsink or use an insulating pad.","metaTitle":"STPLED524 N-Channel MOSFET, 525V, 4A, TO-220-3","metaDescription":"STPLED524 N-channel MOSFET, 525 V Vdss, 4 A continuous drain, 2.6 Ohm Rds(on), TO-220-3 package.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"Mfr":"STMicroelectronics","Series":"-","Package":"Tube","FET Type":"N-Channel","Vgs (Max)":"±30V","Technology":"MOSFET (Metal Oxide)","FET Feature":"-","Mounting Type":"Through Hole","Package / Case":"TO-220-3","Product Status":"Active","lifecycle_stage":"eol_hot","Vgs(th) (Max) @ Id":"4.5V @ 50µA","Base Product Number":"STPLED524","Operating Temperature":"-55°C~150°C(TJ)","Rds On (Max) @ Id, Vgs":"2.6Ohm @ 2.2A, 10V","Power Dissipation (Max)":"45W (Tc)","Supplier Device Package":"TO-220","Gate Charge (Qg) (Max) @ Vgs":"12 nC @ 10 V","Drain to Source Voltage (Vdss)":"525 V","Input Capacitance (Ciss) (Max) @ Vds":"340 pF @ 100 V","Drive Voltage (Max Rds On, Min Rds On)":"10V","Current - Continuous Drain (Id) @ 25°C":"4A (Tc)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/ab8ab06411ee54faa21339e92a6c5c1e.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STPLED524/alternatives.json"},"ai":{"faq":[{"question":"What is the Rds(on) of STPLED524?","answer":"The maximum on-resistance is 2.6 Ohms at 2.2 A drain current with 10 V gate-to-source drive."},{"question":"What is the equivalent or replacement for STPLED524?","answer":"No pin-compatible second source or official replacement is listed in the manufacturer's documentation.
