Product details

Transient protection for a 154V rail

The 1.5KE180A-E3/73: The 246V clamping ceiling means a 154V DC bus — common in three-phase rectified industrial supplies or telecom rectifiers — stays within the safe operating area of downstream components during a surge event.

Housed in a DO-201AA (DO-27) axial-lead package, the 1.5KE180A-/73 mounts through-hole. The 1.5KE package code corresponds to the standard 0.040-inch lead diameter and 0.375-inch body length — the same footprint as other 1.5KE-series devices, simplifying BOM consolidation.

Frequently asked questions

What package does the 1.5KE180A-/73 use?

It comes in a DO-201AA (DO-27) axial-lead through-hole package, compatible with standard 1.5KE-series PCB layouts.
