It delivers up to 27 W from an isolated flyback topology, switching at 65 kHz. The built-in startup cell, current-mode control, and comprehensive fault protections (current limiting, over-load, over-temperature, over-voltage) reduce external component count for AC-DC auxiliary supplies, charger adapters, and industrial power modules. ## Through-hole PG-DIP-8 — field-swappable The PG-DIP-8 package with 0.300\" (7.62 mm) pin spacing is a through-hole part, which means it can be swapped on a customer site with a basic soldering iron and a solder sucker. No hot-air station, no reflow profile. ## Temperature range and environment Rated for a junction temperature range of -40°C to 150°C, this part handles industrial enclosures, outdoor telecom cabinets, and engine-bay-adjacent electronics. The 150°C TJ max is the silicon limit, not the case temperature.","metaTitle":"Infineon ICE3BR4765JFKLA1 CoolSET F3R Flyback, 650V, 65kHz","metaDescription":"Infineon ICE3BR4765JFKLA1 CoolSET F3R offline flyback switch, 650V breakdown, 65kHz, 27W, PG-DIP-8, -40 to 150°C.
