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. ## Obsolete – plan last-time buy or alternate now onsemi has marked the 1.5KE22ARL4 as Obsolete.","metaTitle":"1.5KE22ARL4 onsemi Zener TVS – 18.8V Standoff, 1500W","metaDescription":"onsemi 1.5KE22ARL4 Zener TVS diode, 18.8V reverse standoff, 1500W peak pulse, DO-201AD axial.
