Protection envelope — 1500W peak pulse, 18.2V clamp
The 1.5KE13AE3/TR13: This is a 1500W (1.5kW) peak pulse power Zener TVS diode, unidirectional, single-channel. Peak pulse current (10/1000µs waveform) is 82A. The -65°C to 150°C junction operating range suits deployment in outdoor, industrial, or aerospace environments where temperature extremes are routine. No power line protection — it is a general-purpose transient suppressor, not a primary AC mains protector.
DO-201AA axial — through-hole board fit
Packaged in a DO-201AA / DO-27 axial-lead through-hole case (supplier device package CASE-1). The axial leads are suited for point-to-point wiring or PCB through-hole mounting; the body diameter and lead spacing are standard for this power class. Supplied on Tape & Reel — the reel format is typical for automated insertion, but surplus lots may arrive as cut tape or loose parts depending on the auction source.
