Availability is lot-specific and verified against the RFQ quantity — no ongoing factory pipeline exists. ## AEC-Q101 qualification and 175°C junction This TVS belongs to the Automotive TransZorb series with AEC-Q101 qualification, meaning it meets the automotive-grade reliability stress and temperature cycling requirements for under-hood or chassis-mounted electronics. The operating junction temperature range spans -55°C to +175°C, which covers the full automotive ambient envelope including engine-bay heat soak. ## 1.5 kW peak pulse — clamping at 246 V This is the energy-absorption spec that determines whether the TVS survives a given surge without failing short. The reverse standoff voltage is 154 V, and breakdown occurs between 171 V minimum — so a 154 V nominal rail sees no leakage at steady state, but the device triggers before the rail exceeds 171 V. ## Bidirectional single-channel axial package Single bidirectional channel in a DO-201AA (DO-27) axial leaded package, through-hole mount. The 1.5KE body code is marked on the device.","metaTitle":"1.5KE180CAHE3/51 Vishay TVS, 1.5kW, 154V Standoff","metaDescription":"Obsolete Vishay 1.5KE180CAHE3/51 bidirectional TVS diode, 1500W peak pulse, AEC-Q101 qualified.
