Product details

Clamping window for a 400 V rail

The 1.5KE480A-B: The 408 V standoff sits just above a nominal 400 V DC bus — the diode remains transparent during normal operation and only conducts when a transient pushes the rail past the breakdown threshold.

DO-201 axial — through-hole fit and thermal path

Housed in a DO-201AA / DO-27 axial-lead package (supplier device package DO-201), the part mounts through-hole and is compatible with existing PCB layouts for the 1.5KE series — the lead spacing and body diameter match the standard footprint. The junction temperature range spans -55 °C to 175 °C, covering industrial enclosures and automotive under-hood environments where ambient heat plus self-heating from repetitive surges must stay within the die rating.

Frequently asked questions

What package does 1.5KE480A-B come in?

It is supplied in a DO-201AA / DO-27 axial-lead through-hole package (supplier device package DO-201), shipped in bulk. The lead spacing and body diameter match the standard footprint for the 1.5KE series.
