Its 18.8V reverse standoff voltage and 20.9V minimum breakdown voltage define the protection threshold for a nominal 18V rail; clamping is specified at 30.6V maximum at the 49A peak pulse current. The DO-201AD axial package handles the thermal surge through the lead-frame body, but the through-hole mount means the PCB hole diameter and solder fillet must carry the pulse energy without lifting the pad. ## Obsolete status and sourcing path onsemi has marked the 1.5KE22ARL4G as Obsolete. For a BOM line that still calls out this exact order code, the only procurement path is the open market or surplus inventory — we source and quote against your RFQ quantity. ## Temperature range and application fit Operating junction temperature spans -65°C to 175°C, which covers military and industrial environments — the 175°C ceiling is the same as many high-reliability Zener TVS diodes. The part carries no power-line protection rating, so it is intended for signal or low-voltage DC rail clamping, not AC mains surge suppression.","metaTitle":"1.5KE22ARL4G onsemi Mosorb™ Zener TVS – Obsolete, 1500W","metaDescription":"1.5KE22ARL4G onsemi Zener TVS diode, 1500W peak pulse, 18.8V standoff, 20.9V breakdown, 30.6V clamp.
