The input capacitance is 1480 pF at 25 V drain-source. These figures are moderate for a 550 V, 20 A device and are compatible with standard MOSFET gate-drive ICs, but the gate threshold voltage maximum of 5 V at 250 µA means the drive voltage must be at least 10 V to achieve the rated on-resistance. Heatsinking and airflow are essential for any load above a few amperes.","metaTitle":"STP20NM50FP N-Channel MOSFET, 550V 20A TO-220FP, Obsolete","metaDescription":"STP20NM50FP MDmesh N-Channel MOSFET, 550V Vdss, 20A Id, 250mOhm Rds(on).","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Discrete Semiconductors"],"specifications":{"Mfr":"STMicroelectronics","Series":"MDmesh™","Package":"Tube","FET Type":"N-Channel","Vgs (Max)":"±30V","Technology":"MOSFET (Metal Oxide)","FET Feature":"-","Mounting Type":"Through Hole","Package / Case":"TO-220-3 Full Pack","Product Status":"Obsolete","lifecycle_stage":"eol_hot","Vgs(th) (Max) @ Id":"5V @ 250µA","Base Product Number":"STP20N","Operating Temperature":"-65°C~150°C(TJ)","Rds On (Max) @ Id, Vgs":"250mOhm @ 10A, 10V","Power Dissipation (Max)":"45W (Tc)","Supplier Device Package":"TO-220FP","Gate Charge (Qg) (Max) @ Vgs":"56 nC @ 10 V","Drain to Source Voltage (Vdss)":"550 V","Input Capacitance (Ciss) (Max) @ Vds":"1480 pF @ 25 V","Drive Voltage (Max Rds On, Min Rds On)":"10V","Current - Continuous Drain (Id) @ 25°C":"20A (Tc)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$6.7200","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/c76f5656c84c587073c8fcd1addbde51.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STP20NM50FP/alternatives.json"},"ai":{"faq":[{"question":"Is the STP20NM50FP obsolete and what is a replacement?","answer":"Yes, the STP20NM50FP is listed as Obsolete. STMicroelectronics no longer produces it. A direct replacement would be another MDmesh N-channel MOSFET in the TO-220FP package with a 550 V or higher drain-source rating and similar current and on-resistance.
