It delivers up to 74 W in isolated flyback topologies, switching at a fixed 65 kHz. The part includes built-in fault protection for current limiting, open loop, overload, over-temperature, and over-voltage conditions, making it a self-contained solution for AC-DC auxiliary supplies, industrial power bricks, and appliance power stages where through-hole assembly and a wide operating junction temperature range (-40°C to 150°C) are required. ## Active lifecycle — no LTB pressure This part carries an Active product status with ROHS3 compliance. There is no last-time-buy notice or end-of-life risk on the horizon. For dual-sourcing or a higher-voltage alternative, the ICE3AR1080VJZXKLA1 (800 V breakdown, 71 W, 100 kHz) is a pin-compatible through-hole option in the same CoolSET™F3R series — useful if your input stage needs extra voltage margin or you want a second qualified source. ## Through-hole DIP-8 — board-level fit The PG-DIP-8 package (0.300\" body width, 7.62 mm pitch) is a standard through-hole footprint. It suits wave-solder assembly, manual rework, and prototyping. The 10.5 V to 25 V Vcc supply range and 18 V start-up threshold are typical for auxiliary windings in flyback converters; verify your bias winding delivers at least 18 V during start-up to avoid hiccup mode.","metaTitle":"Infineon ICE3BR0665JXKLA1 CoolSET Flyback, 74W, 650V, 65kHz","metaDescription":"Infineon ICE3BR0665JXKLA1 CoolSET F3R offline flyback switcher: 74W, 650V breakdown, 65kHz, DIP-8.
