Rated for 1500W (1.5kW) peak pulse power over a junction temperature range of -65°C to 175°C, it suits high-reliability environments such as industrial power supplies, automotive modules, and telecom line cards where surge immunity is critical. ## Through-hole axial package and mounting Housed in a DO-201AD axial-lead package, the 1N6281ARL4 is a through-hole component suited for wave-solder assembly. The package is supplied on Tape & Reel (TR) for automated insertion, though the obsolete status means reel quantities may be limited to existing distributor stock. ## Obsolete — sourcing through independent channels onsemi lists the 1N6281ARL4 as Obsolete. For a BOM line requiring this exact order code, procurement must source through independent distributors or excess inventory channels.","metaTitle":"1N6281ARL4 Zener TVS Diode – 1500W, DO-201AD, Obsolete","metaDescription":"onsemi 1N6281ARL4 Mosorb™ Zener TVS diode, 1500W peak pulse power, 23.1V standoff, DO-201AD axial.
