The 90 V minimum breakdown voltage gives a guard band above the 81 V standoff — the device starts conducting between 90 V and the clamping ceiling, not at the standoff level. ## Obsolete — sourced through independent channels Vishay lists the 1.5KE100C-/73 as obsolete, meaning the original manufacturer no longer produces it. The DO-201AA axial package and through-hole mounting are standard for this power class, so a replacement from another manufacturer with the same footprint and 1.5 kW rating is a functional cross-shop candidate, but no direct drop-in is documented.","metaTitle":"1.5KE100C-E3/73 TransZorb TVS, 1.5kW, 81V Standoff","metaDescription":"Vishay 1.5KE100C-E3/73 bidirectional Zener TVS diode, 1500W peak pulse, 81V reverse standoff, DO-201AA axial.
