That means availability is opportunistic: you cannot place a factory order or book a last-time buy. ## Gate charge and capacitance — switching budget The total gate charge is 32 nC at a 10 V gate drive, with an input capacitance of 750 pF measured at 25 V Vds. For a 100 kHz hard-switched converter, the gate-drive power loss is roughly Qg × Vgs × fsw — about 32 mW per switch at 10 V drive — which is manageable with a standard driver. The 750 pF input capacitance also means the driver sees a moderate capacitive load; rise and fall times will be clean with a 1 A to 2 A gate-drive stage.","metaTitle":"Infineon SPA08N50C3XKSA1 CoolMOS N-Ch MOSFET, 560 V, 7.6 A","metaDescription":"Infineon SPA08N50C3XKSA1 CoolMOS N-channel MOSFET, 560 V Vdss, 7.6 A Id, 600 mOhm Rds(on), TO-220 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 @ 350µA","Base Product Number":"SPA08N","Operating Temperature":"-55°C ~ 150°C (TJ)","Rds On (Max) @ Id, Vgs":"600mOhm @ 4.6A, 10V","Power Dissipation (Max)":"32W (Tc)","Supplier Device Package":"PG-TO220-3-31","Gate Charge (Qg) (Max) @ Vgs":"32 nC @ 10 V","Drain to Source Voltage (Vdss)":"560 V","Input Capacitance (Ciss) (Max) @ Vds":"750 pF @ 25 V","Drive Voltage (Max Rds On, Min Rds On)":"10V","Current - Continuous Drain (Id) @ 25°C":"7.6A (Tc)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.7400","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/1b0b8996d75aa693e64b376951f6ec5e.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Where can I buy SPA08N50C3XKSA1?","answer":"This part is obsolete, so it is not available through franchised distribution for new factory orders. We source it through independent channels — surplus stock, overstock, or broker inventory. Submit an RFQ with your target quantity and price; we will confirm availability and current pricing at quote time."},{"question":"Is SPA08N50C3XKSA1 obsolete?","answer":"Yes, Infineon has marked the SPA08N50C3XKSA1 as Obsolete."},{"question":"What is the difference between SPA08N50C3 and SPA08N50C3XKSA1?","answer":"The SPA08N50C3XKSA1 is the specific ordering code variant of the base SPA08N50C3. The difference is typically in packaging, shipping quantity, or regional ordering configuration — the silicon and electrical ratings are the same. Both are obsolete."},{"question":"Can SPA08N50C3XKSA1 be used as a replacement for SPP08N50C3?","answer":"The SPP08N50C3 is a DPAK (TO-252) surface-mount version of the same CoolMOS C3 die, while the SPA08N50C3XKSA1 is a TO-220 Full Pack through-hole part. Electrically they share the same 560 V Vdss and similar Rds(on) and current ratings, but the packages are not pin-compatible.
