Date codes will vary; a reputable broker screens for counterfeit and grades by visual, X-ray, and electrical test. The TO-220FP full-pack package is fully isolated — no exposed metal tab — so the mounting hole is the only thermal path. Plan on a heatsink or forced air if you push past 30 W dissipation, as the package limit is 30 W at case temperature. The tube shipping medium (the package field says Tube) means the parts arrive in anti-static tubes, not tape-and-reel; factor that into your pick-and-place setup if you are hand-loading sockets or a carrier.","metaTitle":"STF60N55F3 N-Channel MOSFET, 55V, 42A, TO-220FP, Obsolete","metaDescription":"STF60N55F3 N-Channel STripFET III MOSFET: 55V Vdss, 42A Id, 8.5mOhm Rds(on).

For a BOM that already uses this MOSFET, the only procurement path is new-old-stock or surplus inventory through independent distributors."},{"question":"What is the equivalent or replacement for STF60N55F3?","answer":"There is no official pin-compatible replacement listed by STMicroelectronics. A drop-in substitute would need to match the TO-220FP full-pack footprint, 55 V minimum Vdss, 42 A continuous drain current, and 8.5 mOhm or lower Rds(on) at 10 V gate drive. The IRF3205 is a common 55 V N-channel MOSFET but comes in a standard TO-220 with an exposed metal tab — it is not a direct pin-compatible swap because the full-pack package is electrically isolated. A layout change would be required."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/STF60N55F3","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/STF60N55F3 when reusing this data.
