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 ## Sourcing and fit check Because the 1.5KE180ARL4 is obsolete, verify that the breakdown voltage and clamping characteristics match your protection requirement before committing to a substitute.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.","metaTitle":"1.5KE180ARL4 onsemi Circuit Protection TVS – Obsolete, Bulk","metaDescription":"onsemi 1.5KE180ARL4 TVS diode, Bulk package, obsolete.
