It clamps transients at 18.2V maximum when the surge current hits, protecting downstream circuitry from overvoltage events. ## Voltage thresholds and operating range Reverse standoff voltage is 11.1V typical, meaning the part stays non-conductive below that level. Breakdown starts at a minimum of 12.4V, and clamping is guaranteed at 18.2V maximum — a tight window that limits the voltage spike seen by the load. ## Package and mounting for rework and retrofit Housed in a DO-201AD axial through-hole package, the 1N6274ARL4G is suited for manual assembly or rework on existing boards. The axial leads allow easy insertion into plated through-holes without special tooling. The single unidirectional channel means this diode protects one polarity line — it is not a bidirectional device, so it cannot be used on AC lines or bipolar signal pairs without an external bridge. onsemi lists the 1N6274ARL4G as Obsolete. There is no official successor or cross-reference in the ledger, so any replacement must be selected based on the same 1.5kW peak pulse rating, 11.1V standoff, and DO-201AD footprint. Because the part is obsolete, sourcing is limited to existing distributor stock or broker channels.","metaTitle":"1N6274ARL4G onsemi Mosorb™ Zener TVS – Obsolete, 1.5kW","metaDescription":"onsemi 1N6274ARL4G Zener TVS, Mosorb™ series, 1.5kW peak pulse, 11.1V standoff, 18.2V clamp.
