That rating is the energy the device can absorb in a single surge event without failing — the buyer's circuit protection budget starts here. Breakdown voltage starts at 37.1V minimum, clamping at 53.9V maximum at the peak pulse current, with a 33.3V reverse standoff. The standoff voltage is the DC rail the part sits across without conducting; the clamp voltage is where the TVS forces the surge current to ground. The gap between them — roughly 20V — is the protection window the load must survive. ## Obsolete – sourcing through independent channels onsemi lists the 1N6285ARL4 as Obsolete. For a BOM line that depends on this part, the only path is the independent surplus market — franchised distributors will not carry it. The package is axial, through-hole, supplied on Tape & Reel. That package is common across the 1N6285 family, so a same-package sibling (e.g. 1N6285A) is a drop-in candidate if the electrical ratings match the application. ## Temperature range and mounting Through-hole axial mounting simplifies hand-rework and retrofit but occupies more board area than a surface-mount equivalent.","metaTitle":"1N6285ARL4 Zener TVS, 1500W, Obsolete – Sourcing Info","metaDescription":"onsemi Mosorb™ 1N6285ARL4 Zener TVS, 1500W peak pulse, 33.3V standoff, DO-201AD axial.
