Clamping specs for a 154V rail
The 1.5KE180CA/B: Its 154V reverse standoff voltage means it sits across a 154V DC or AC line without conducting, then breaks down at 171V minimum and clamps transients to 246V maximum at 6.2A peak pulse current. The 246V clamping ceiling is the number to check against the downstream component's absolute maximum rating — if the protected IC can survive 250V for the pulse duration, this diode keeps it safe.
Through-hole package swaps in the field
Housed in a DO-201AA (DO-27, Axial) through-hole package with a DO-201 supplier device package designation, this diode is a hand-tool swap — no hot-air station needed. The axial leads are polarity-marked on the body; the bidirectional channel means orientation doesn't matter, which cuts the risk of a reverse-install mistake on a service call.
Active production, no end-of-life watch needed
General-purpose application class means it fits power-supply input protection, DC bus clamping, and signal-line transient suppression without a dedicated automotive or telecom qualification — though the wide temperature range covers most industrial environments.
