The through-hole TO-262 package (PG-TO262-3-1) suits designs that need a soldered-in device with good thermal transfer to the heatsink via the exposed tab. For BOM planning, this part is a straightforward line item — no LTB date to track, no forced redesign horizon.","metaTitle":"Infineon SPI12N50C3IN CoolMOS N-Channel MOSFET, 500 V","metaDescription":"Infineon SPI12N50C3IN CoolMOS N-Channel MOSFET, 500 V drain-source, 11.6 A continuous drain, 380 mOhm Rds(on) at 10 V gate drive.","metaKeywords":null},"attributes":{"series":"CoolMOS™","packageCase":null,"mountingType":null,"rohsStatus":"Not applicable","productStatus":"Active","categoryPath":[],"specifications":{"Series":"CoolMOS™","Package":"Bulk","FET Type":"N-Channel","Vgs (Max)":"±20V","Technology":"MOSFET (Metal Oxide)","Mounting Type":"Through Hole","Package / Case":"TO-262-3 Long Leads, I²Pak, TO-262AA","lifecycle_stage":"eol_hot","Vgs(th) (Max) @ Id":"3.9V @ 500µA","Operating Temperature":"-55°C ~ 150°C (TJ)","Rds On (Max) @ Id, Vgs":"380mOhm @ 7A, 10V","Power Dissipation (Max)":"125W (Tc)","Supplier Device Package":"PG-TO262-3-1","Gate Charge (Qg) (Max) @ Vgs":"49 nC @ 10 V","Drain to Source Voltage (Vdss)":"500 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":"$1.04","priceTiers":[{"qty":289,"price":"$1.04000","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/e5dc872126b7447e8d0884c89f8877bf.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/SPI12N50C3IN/alternatives.json"},"ai":{"faq":[{"question":"Is SPI12N50C3IN obsolete or end-of-life?","answer":"No, the SPI12N50C3IN is listed as active in production with no end-of-life status.

However, the gate drive requirement (10 V for rated Rds(on)) and package (TO-262 vs TO-247) differ. Electrically it can work in a 200 V circuit if the higher Rds(on) and gate charge are acceptable, but the footprint and thermal interface must be adapted."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/infineon/SPI12N50C3IN","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/infineon/SPI12N50C3IN when reusing this data.
