It clamps transients at 12.1V maximum, with a reverse standoff of 7.02V — meaning it stays out of the way below that voltage and only conducts when a surge pushes above the 7.79V breakdown threshold. That makes it a fit for protecting 5V and 3.3V rails from lightning, inductive kickback, or ESD events in general-purpose equipment. ## Obsolete — sourcing path and replacement onsemi has marked the 1.5KE8.2ARL4 as Obsolete. That means no further production runs are planned. For a BOM line that still needs this exact order code, the only path is a last-time buy from remaining distributor inventory or the spot market. We can source it per RFQ — confirm the quantity and we'll check our network. For a production alternative, onsemi's 1.5KE series includes electrically equivalent parts in the same footprint. ## Temperature range and mounting The operating junction temperature spans -65°C to 175°C, so this diode can sit in an engine bay, outdoor telecom cabinet, or industrial control panel without thermal derating concerns. It's a through-hole axial part in a DO-201AD package — hand-solderable, breadboard-friendly, and easy to replace during rework. No power line protection built in; it's a straight transient suppressor for signal and low-voltage DC rails.","metaTitle":"1.5KE8.2ARL4 onsemi Zener TVS Diode 1500W DO-201AD Obsolete","metaDescription":"onsemi 1.5KE8.2ARL4 Mosorb™ Zener TVS, 1500W peak pulse, 7.02V standoff, DO-201AD axial.
