Once that window closes, new production ceases. Sourcing shifts to independent distribution where available inventory is lot-specific and confirmed at RFQ. ## Clamping voltage and the circuit it protects The reverse standoff voltage of 154 V means the TVS draws negligible leakage below that rail, so it sits across a 150 V or 155 V bus without interfering with normal operation. Minimum breakdown is 171 V, giving a 17 V window between the standoff and the point where the device starts conducting — tight enough for a regulated 150 V rail. ## 1500 W peak pulse in a DO-201AA axial package The DO-201AA (DO-27) axial leaded package suits through-hole assembly and high-reliability point-to-point wiring in power supplies, industrial controls, and telecom line cards.","metaTitle":"1.5KE180A-E3/51 Vishay TVS, 1500W, 154V Standoff, DO-201AA","metaDescription":"1.5KE180A-E3/51 Vishay TransZorb® TVS, Last Buy status. 1500W peak pulse, 154V standoff, 246V clamp.
