The on-resistance is specified at 90 mOhm maximum when the gate is driven to 10 V and the drain carries 15 A. That 90 mOhm figure is the conduction loss per ampere squared — at 15 A you are looking at roughly 20 W of dissipation just from Rds(on), which needs to be removed through the TO-220 package's tab. The gate-drive voltage is 10 V for the rated Rds(on); driving with a lower gate voltage will increase on-resistance significantly, so your gate driver must supply a clean 10 V rail. This number tells you how much energy the gate driver must push into the gate to switch the device on. In real-world conditions with a heatsink, you will derate this figure based on your thermal impedance. The STP30NM30N comes in a TO-220-3 through-hole package. The metal tab is the drain connection, and the two inner pins are gate and source. The through-hole leads suit wave-soldering or hand-soldering into a PCB with 0.6 mm to 0.8 mm diameter plated holes. ## Lifecycle status — obsolete, sourced to order The STP30NM30N carries an official product status of Obsolete. STMicroelectronics has discontinued this MDmesh™ II part, meaning it is no longer manufactured in volume.","metaTitle":"STP30NM30N N-Channel MOSFET, 300 V, 30 A, MDmesh™ II","metaDescription":"STP30NM30N N-Channel MOSFET from STMicroelectronics, 300 V Vdss, 30 A continuous drain, 90 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":"MDmesh™ II","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":"4V @ 250µA","Base Product Number":"STP30N","Operating Temperature":"-65°C~150°C(TJ)","Rds On (Max) @ Id, Vgs":"90mOhm @ 15A, 10V","Power Dissipation (Max)":"160W (Tc)","Supplier Device Package":"TO-220","Gate Charge (Qg) (Max) @ Vgs":"75 nC @ 10 V","Drain to Source Voltage (Vdss)":"300 V","Input Capacitance (Ciss) (Max) @ Vds":"2500 pF @ 50 V","Drive Voltage (Max Rds On, Min Rds On)":"10V","Current - Continuous Drain (Id) @ 25°C":"30A (Tc)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/e5b527b737b8b030737816543df2a0eb.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STP30NM30N/alternatives.json"},"ai":{"faq":[{"question":"What is the Vgs threshold of STP30NM30N?","answer":"The maximum gate threshold voltage (Vgs(th)) is 4 V at a drain current of 250 µA.
