For a 12V rail, the 11.1V reverse standoff means it sits across the line without conducting during normal operation, then clamps transients above 12.4V breakdown to 18.2V. ## Field-swap note: through-hole axial package Housed in a DO-201AA/DO-27 axial leaded package, this is a through-hole part — no hot-air station needed, just a soldering iron and a steady hand. The body is marked with the polarity band, so orientation is one-look obvious. ## Sourcing an obsolete part Diodes Incorporated lists the 1.5KE13A-T as Obsolete. That means the factory line is closed — no new manufacturing. No official successor is recorded from Diodes, so the BOM line relies on existing inventory or a functional replacement with a different pinout. ## Where it fits in the protection scheme The unidirectional channel means it protects one line referenced to ground — typical for a single 12V sensor supply or a communication bus like RS-485. The 82A peak pulse current at 10/1000µs gives the surge capacity for industrial transient environments per IEC 61000-4-5.","metaTitle":"1.5KE13A-T Diodes Inc Zener TVS, 1500W, DO-201","metaDescription":"Obsolete 1.5KE13A-T Zener TVS diode, 1500W peak pulse, 11.1V standoff, 18.2V clamp.
