That 12.1 V window between standoff and clamp gives the designer headroom for tolerance on the upstream rail while keeping the protected IC within its abs-max rating. ## Through-hole axial package and thermal reach Housed in a DO-201AA (DO-27) axial-lead package, the 1.5KE22-/73 is a through-hole part intended for point-to-point wiring or PCB mounting with the leads formed. The axial body conducts heat into the board traces — for sustained repetitive surges, the trace copper area sets the derating curve, not the die itself. ## Obsolete — sourcing through independent channels Vishay has marked the 1.5KE22-/73 as obsolete. No official successor order code is recorded.","metaTitle":"1.5KE22-E3/73 Vishay TVS Zener, 1500W, 17.8V Standoff","metaDescription":"1.5KE22-E3/73 Vishay TransZorb® Zener TVS, 1500W peak pulse, 17.8V reverse standoff, DO-201AA axial.
