Product details

The 1.5KE82A A0G: For a 70.1V DC rail (the reverse standoff voltage), it stays out of the circuit until a surge pushes it past the 77.9V minimum breakdown threshold, then clamps at 113V maximum to shunt the current away from your load.

Field-fit and package note

Through-hole DO-201AA / DO-27 axial package — the leads are 0.96 mm diameter and the body is about 9 mm long. It is a straightforward hand-solder swap on a site visit if you have a standard iron and a desoldering pump; no hot-air station needed. The cathode band is clearly marked on the body, so orientation is one-look correct.
