Availability is lot-specific and confirmed at RFQ time; no franchised pipeline remains. ## 1500 W peak pulse — the protection envelope The reverse standoff voltage is 89.2 V, meaning the device stays off below that rail level and only conducts when the surge exceeds the 99 V minimum breakdown threshold. This is a unidirectional Zener-type TVS — single-channel, no power-line protection rating — suited for DC rail clamping where the polarity is fixed and the surge energy fits within the 1500 W envelope. ## DO-201AA axial — through-hole footprint for legacy layouts Housed in the DO-201AA (DO-27) axial-lead package, the 1.5KE110-/73 is a through-hole part. The supplier device package code is 1.5KE. The operating junction temperature range spans -55°C to 175°C, covering industrial and military-grade thermal environments without derating concerns at the high end. The TransZorb series is Vishay's branded TVS family, known for tight clamping and fast response. No second-source or pin-compatible drop-in replacement is recorded from the original manufacturer.","metaTitle":"1.5KE110-E3/73 Vishay TransZorb TVS, 1500W, 158V Clamp","metaDescription":"Vishay 1.5KE110-E3/73 TransZorb Zener TVS diode, 1500W peak pulse, 158V clamping, DO-201AA axial.
