Product details

18.8V standoff, 1500W peak pulse – TVS for 12V/15V rails

It handles 1500W peak pulse power per the 10/1000µs waveform, clamping at 30.6V maximum while conducting 49A peak pulse current. The 18.8V standoff suits nominal 12V or 15V rails where the TVS must not conduct during normal operation but triggers before the downstream components' absolute maximum rating. The 1500W rating gives headroom for industrial surge requirements like IEC 61000-4-5 Level 4.

DO-201AD axial – through-hole mounting, wide temperature range

Housed in a DO-201AD axial package, the 1.5KE22ARL4 mounts through-hole, which simplifies hand-assembly and rework but consumes more board area than surface-mount alternatives.
