The breakdown window starts at 171V minimum — so a transient that drives the line above that threshold triggers the avalanche, and the diode shunts the energy until the clamp voltage is reached. For a 1500W pulse, the 6.4A peak current is the limit; a higher surge would exceed the die's thermal capacity and risk failure. The DO-201AA axial through-hole package (also known as DO-27) provides a robust mechanical anchor on the board — the lead bends absorb vibration better than a surface-mount package in high-shock automotive or industrial applications.","metaTitle":"1.5KE180CAH TVS Diode, 1500W, Bidirectional, DO-201","metaDescription":"Taiwan Semiconductor 1.5KE180CAH automotive TVS diode, 1500W peak pulse, 154V standoff, 246V clamp, AEC-Q101, DO-201.
