Its 7.79V minimum breakdown voltage and 12.1V clamping ceiling make it a fit for 5V or 6V supply lines where a 7V reverse standoff (7.02V typ) keeps it out of conduction during normal operation. The DO-201AD axial package suits through-hole assembly on industrial control boards, power supplies, and telecom line cards where a single unidirectional channel handles the surge. ## Package and mounting At the 10/1000µs waveform, this part clamps 124A peak pulse current to 12.1V max — the energy rating is 1500W, but derating above 25°C ambient follows the standard power-temperature curve for axial TVS diodes. The junction temperature range of -65°C to 175°C covers most industrial and outdoor enclosures without a derating penalty at the cold end. No power line protection rating means it is intended for signal or low-voltage DC rail clamping, not AC mains primary-side suppression. ## Obsolete status and what that means for your BOM For a board that already carries this part, a last-time buy through an RFQ is the cleanest path to secure inventory before the remaining distributor stock dries up. The base product number 1.5KE covers a broad family of axial TVS diodes; a cross to a same-rating sibling in the 1.5KE series (e.g., 1.5KE8.2A in a different package suffix or lead-free finish) may be possible, but the exact order code 1.5KE8.2ARL4G is no longer manufactured.","metaTitle":"1.5KE8.2ARL4G onsemi Zener TVS Diode – Obsolete, 1500W","metaDescription":"onsemi 1.5KE8.2ARL4G Zener TVS, 1500W peak pulse, 7.79V breakdown, DO-201AD axial.
