It offers a reverse standoff voltage of 13.6V, a minimum breakdown voltage of 15.2V, and clamps at 22.5V maximum, making it suitable for protecting 12V nominal rails from surges. The DO-201AD axial package suits point-to-point wiring or PCB through-hole mounting, and the -65°C to 175°C junction temperature range covers automotive underhood and industrial environments. ## Lifecycle status and sourcing reality onsemi has marked the 1N6276ARL4 as Obsolete, meaning no ongoing production. Remaining stock on tape and reel is the only source. If your BOM needs this exact part, request a quote for available inventory — we source from multiple distributor channels and can confirm current availability at quote time. For new designs or long-term support, plan a cross-reference to an active TVS with similar 13.6V standoff and 1500W rating in a DO-201AD or surface-mount equivalent.","metaTitle":"1N6276ARL4 onsemi Mosorb™ Zener TVS, 1500W, DO-201AD","metaDescription":"1N6276ARL4 onsemi Mosorb™ Zener TVS diode, 1500W peak pulse, 13.6V standoff, DO-201AD axial.
