Product details

The 1.5KE180ARL4 is a transient-voltage-suppression (TVS) diode from onsemi's 1.5KE series, designed to clamp voltage spikes on power rails and signal lines in industrial and telecom equipment. — loose devices, not tape-and-reel — which suits bench-level assembly or low-volume production but requires manual handling for pick-and-place.

Lifecycle reality: obsolete, plan your BOM

For a BOM that requires this exact order code, the only sourcing path is existing distributor or broker inventory. Confirm availability and lead time at quote; a last-time buy may not be possible.

Sourcing and fit check

Because the 1.5KE180ARL4 is obsolete, verify that the breakdown voltage and clamping characteristics match your protection requirement before committing to a substitute. The part is not moisture-sensitive per standard JEDEC levels, but bulk loose devices can accumulate static charge if not handled properly.

Frequently asked questions

What is the replacement or cross-reference for 1.5KE180ARL4?

onsemi has not published an official replacement or cross-reference for the 1.5KE180ARL4. For a drop-in substitute, compare the breakdown voltage and peak pulse power of other 1.5KE-series TVS diodes (e.g., 1.5KE180A) — but confirm the exact electrical and package compatibility from the original BOM.
