When a surge hits a 154V bus, the device breaks down at 171V minimum and clamps the transient to 246V maximum while shunting 6.1A of peak pulse current (10/1000µs waveform). That 17V margin between standoff and breakdown means the diode stays off under normal 154V operation and only conducts when the rail actually exceeds the safe limit. ## Automotive qualification and deployment context This part carries AEC-Q101 qualification — the automotive discrete semiconductor stress test that covers temperature cycling, high-temperature reverse bias, and ESD robustness. The through-hole axial package is not a space-saver, but the leaded form factor handles the thermal cycling of engine-bay environments better than a surface-mount part of the same power class.","metaTitle":"1.5KE180AHE3_B/C Vishay TVS, 1500W, 154V Standoff, AEC-Q101","metaDescription":"Vishay 1.5KE180AHE3_B/C TransZorb TVS, 1500W peak pulse, 154V standoff, 246V clamp.
