The trade-off is thermal resistance — expect roughly double the junction-to-case thermal impedance compared to a standard TO-220 with an exposed metal tab. The 33 W dissipation ceiling reflects that. For through-hole mounting, the three leads are standard 0.1-inch pitch; the body is wider than a standard TO-220, so check the heatsink clip clearance if you are retrofitting an existing layout. The 150°C Tj(max) is typical for CoolMOS™; the 3.9 V maximum threshold at 500 µA is on the higher side, which helps with dv/dt immunity in half-bridge topologies but means the gate drive must swing cleanly above 10 V to keep Rds(on) in spec at cold temperatures.","metaTitle":"Infineon SPA12N50C3XKSA1 CoolMOS™ N-Ch 560V 11.6A TO-220FP","metaDescription":"Infineon SPA12N50C3XKSA1 CoolMOS™ N-channel MOSFET, 560V Vdss, 11.6A Id, 380mOhm Rds(on), TO-220-3 Full Pack.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Discrete Semiconductors"],"specifications":{"Mfr":"Infineon Technologies","Series":"CoolMOS™","Package":"Tube","FET Type":"N-Channel","Vgs (Max)":"±20V","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":"3.9V @ 500µA","Base Product Number":"SPA12N","Operating Temperature":"-55°C ~ 150°C (TJ)","Rds On (Max) @ Id, Vgs":"380mOhm @ 7A, 10V","Power Dissipation (Max)":"33W (Tc)","Supplier Device Package":"PG-TO220-3-31","Gate Charge (Qg) (Max) @ Vgs":"49 nC @ 10 V","Drain to Source Voltage (Vdss)":"560 V","Input Capacitance (Ciss) (Max) @ Vds":"1200 pF @ 25 V","Drive Voltage (Max Rds On, Min Rds On)":"10V","Current - Continuous Drain (Id) @ 25°C":"11.6A (Tc)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.5461","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/cde3287b1078560b55cf0702495ecf71.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the replacement or equivalent for SPA12N50C3XKSA1?","answer":"Infineon does not list a direct pin-compatible successor for this specific order code in the lifecycle record. The CoolMOS™ C3 generation has been superseded by newer families like CoolMOS™ P7 and CFD7, but those are different process generations and may have different gate drive characteristics or package options. A parametric search for a 560 V, 11 A class, TO-220 Full Pack N-channel FET with 10 V gate drive is the practical approach for a replacement — verify the gate charge and capacitance match the switching frequency of your design before swapping."},{"question":"What is the Rds(on) of SPA12N50C3XKSA1?","answer":"The maximum Rds(on) is 380 mOhm at 7 A drain current with 10 V gate drive.
