Breakdown occurs between 162 V min, and the clamp hardens at 258 V max. The 16 V gap between standoff and breakdown gives the designer margin to absorb rail ripple without the TVS self-triggering on normal line noise. ## Obsolete — sourcing through independent channels Vishay has marked the 1.5KE180-/73 as obsolete. A board spin to a current-production TVS in the same DO-201AA footprint may be the more repeatable path for a new BOM. ## Thermal and package envelope Junction temperature range spans -55 °C to 175 °C — suited to high-reliability environments where the TVS sees repetitive surge events and the die temperature climbs above the 125 °C common for commercial-grade parts. The DO-201AA axial package (DO-27 equivalent) is a through-hole form factor, and the 1.5KE family suffix on the supplier device package matches the standard Vishay marking for this die size.","metaTitle":"Vishay 1.5KE180-E3/73 TransZorb TVS, 1500W, 258V Clamp","metaDescription":"Obsolete Vishay 1.5KE180-E3/73 TransZorb Zener TVS, 1500W peak pulse, 258V clamp, DO-201AA.
