Its 6.45V minimum breakdown voltage triggers clamping at 10.5V maximum under peak pulse current, absorbing 1500W of surge energy in a DO-201AD axial package. ## Surge rating and thermal limits Rated for 1500W peak pulse power at 1ms pulse width, the 1N6267ARL4 handles high-energy transients typical of inductive load switching or lightning surge on low-voltage DC buses. The junction operates from -65°C to 175°C, so the part can sit in hot environments like an engine bay or power supply output without derating the clamping voltage. ## Obsolete – sourcing window is closing onsemi has marked the 1N6267ARL4 as Obsolete. No official successor is listed on the record. For existing BOM lines, the last-time buy window is effectively past – remaining stock in franchised or independent channels is the only supply. Sourcing is per RFQ; availability and pricing are confirmed at quote time against the required quantity. ## Package and mounting Through-hole axial package with tape-and-reel or cut-tape options. The axial leads suit point-to-point wiring or PCB through-hole mounting.","metaTitle":"1N6267ARL4 Zener TVS Diode – onsemi Mosorb™ 1500W Obsolete","metaDescription":"onsemi 1N6267ARL4 Mosorb™ Zener TVS, 1500W peak pulse, DO-201AD axial, 6.45V breakdown.
