The 12.8 V reverse standoff sits above the 12 V nominal rail, so the diode does not leak during normal operation but triggers before the downstream IC's abs-max rating is reached. ## Clamping performance at 1500 W Breakdown occurs at a minimum of 14.3 V, with clamping held to 21.2 V at the rated 74 A peak pulse current. For a 12 V system, this leaves roughly 9 V of headroom between the clamp voltage and a typical 30 V abs-max on a protected ECU input — enough margin for most automotive transient profiles. The single bidirectional channel suppresses both positive and negative transients in one package, reducing component count on a 12 V bus. ## Sourcing and compliance Listed as Active in production by Taiwan Semiconductor Corporation.","metaTitle":"1.5KE15CAH TVS Diode, 1500W, 12.8V, DO-201, AEC-Q101","metaDescription":"Taiwan Semiconductor 1.5KE15CAH bidirectional Zener TVS diode, 1500W peak pulse, 12.8V standoff, DO-201 axial.
