The through-hole DO-201AA/DO-27 axial package mounts in standard 0.100-inch pitch board layouts, suitable for retrofitting into existing automotive ECU or powertrain protection designs. ## Lifecycle reality — obsolete, sourced through surplus Vishay lists the 1.5KE12AHE3/51 as Obsolete, meaning the manufacturer has ceased production and no last-time-buy window remains open. For BOM lines requiring this exact part number, the only supply channel is independent surplus and broker inventory. Availability is lot-specific; quantities are confirmed at RFQ. The AEC-Q101 qualification and TransZorb® construction mean any replacement must meet similar peak pulse power and clamping specs to maintain the same circuit protection margin.","metaTitle":"Vishay 1.5KE12AHE3/51 TVS Diode, 1500W, 10.2V Standoff","metaDescription":"Obsolete Vishay 1.5KE12AHE3/51 unidirectional TVS, 1500W peak pulse, 10.2V reverse standoff, AEC-Q101 qualified.
