Breakdown occurs at 171V minimum, and the clamping voltage is capped at 246V at the 6.4A peak pulse current (10/1000µs). This gives a 92V window between the rail and the clamp, enough to absorb common automotive load-dump and inductive-kick transients. Power line protection is not supported — the part is designed for signal or low-power supply rails, not for direct mains or high-current bus clamping.","metaTitle":"1.5KE180CAHB0G TVS Diode, 1500W, Bidirectional, DO-201","metaDescription":"Taiwan Semiconductor 1.5KE180CAHB0G Zener TVS, 1500W peak pulse, 154V standoff, AEC-Q101.
