Product details

TVS diode for legacy board protection

The 1.5KE180-B: The reverse standoff voltage is 154V, with a minimum breakdown of 162V — meaning the device starts conducting between those thresholds and clamps the surge before it damages downstream silicon.

Package and mounting for through-hole assembly

Housed in a DO-201AA (DO-27) axial-lead package, the 1.5KE180-B mounts through-hole — the leads are formed for axial insertion and wave-solder compatible. Supplied in bulk packaging — no tape-and-reel, so plan for hand or tube feeding if your pick-and-place handles axial parts.
