The TO-220FP isolates the tab electrically, eliminating the need for an insulating pad. ## Obsolete — planning the last-time-buy or cross-reference ST has marked the STF21NM60N as Obsolete. The MDmesh™ series includes several 600 V N-channel devices in TO-220FP, but pin-compatibility and gate-drive thresholds should be verified against the original layout and thermal budget. ## Gate charge and input capacitance — switching loss drivers A 66 nC Qg at 10 V and 1900 pF Ciss at 50 V set the switching speed and gate-drive power requirement.","metaTitle":"STF21NM60N N-Channel MOSFET, 600 V, 220 mOhm, TO-220FP","metaDescription":"STF21NM60N N-channel MDmesh MOSFET, 600 Vdss, 17 A, 220 mOhm 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)":"±25V","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":"4V @ 250µA","Base Product Number":"STF21","Operating Temperature":"150°C(TJ)","Rds On (Max) @ Id, Vgs":"220mOhm @ 8.5A, 10V","Power Dissipation (Max)":"30W (Tc)","Supplier Device Package":"TO-220FP","Gate Charge (Qg) (Max) @ Vgs":"66 nC @ 10 V","Drain to Source Voltage (Vdss)":"600 V","Input Capacitance (Ciss) (Max) @ Vds":"1900 pF @ 50 V","Drive Voltage (Max Rds On, Min Rds On)":"10V","Current - Continuous Drain (Id) @ 25°C":"17A (Tc)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/620de0d483d1bfe4290d8a81bf1568b7.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STF21NM60N/alternatives.json"},"ai":{"faq":[{"question":"What is the Rds(on) of STF21NM60N?","answer":"This is the figure to use for worst-case conduction loss calculations in your power stage."},{"question":"Is STF21NM60N obsolete?","answer":"Yes, ST has classified the STF21NM60N as Obsolete.
