Product details

Flyback switcher for 71 W isolated supplies

The Infineon ICE3AR1080VJZXKLA1 is an offline flyback PWM controller with an integrated 800 V CoolMOS power switch, part of the CoolSET F3R family. It delivers up to 71 W in a single-switch flyback topology with output isolation.

Through-hole DIP-7 — fit and footprint

The PG-DIP-7-1 package is a 7-lead DIP with 0.300" body width. It is a through-hole mount — no reflow, wave-solder or hand-solder only. The 7-lead variant has a dedicated drain tab pin for thermal relief to the PCB copper.

Frequently asked questions

What is the equivalent part for ICE3AR1080VJZXKLA1?

The closest functional peer in the same CoolSET F3R through-hole family is the ICE3BR0665JXKLA1, which is a 74 W flyback with 650 V breakdown and 65 kHz switching. The 800 V breakdown and 100 kHz frequency of the ICE3AR1080VJZXKLA1 are not matched by that part; check if your design can accept the lower voltage margin and slower switching before substituting.

Does ICE3AR1080VJZXKLA1 require an external heatsink?

At the full 71 W output, a heatsink is required. The through-hole DIP-7 package has a thermal tab that accepts a clip-on or bolted heatsink. The 150°C junction rating gives thermal headroom, but the copper area on the PCB alone is not enough to dissipate 71 W continuously.

Is ICE3AR1080VJZXKLA1 compatible with 230V AC input?

Yes. The 800 V breakdown rating provides margin above the rectified DC bus (about 370 VDC for 265 VAC input) plus the reflected voltage and leakage spike typical in a flyback. It is designed for universal AC input, including 230 VAC lines.
