AEC-Q101 qualification adds the reliability screening — temperature cycling, high-temperature reverse bias, and ESD robustness — required for under-hood and chassis-mounted electronics where ambient temperatures reach 125 °C. ## Through-hole DO-201 package for high-reliability assembly The DO-201AA (DO-27) axial-lead through-hole package suits high-reliability and high-temperature applications where surface-mount solder joints may fatigue under thermal cycling. The junction operates from -55 °C to 175 °C, covering the full automotive temperature grade with margin for engine-bay heat soak. No power line protection feature is implemented — this is a unidirectional or bidirectional transient suppressor, not a crowbar or foldback device.","metaTitle":"1.5KE150CAHA0G TVS Diode, 1500W, 207V Clamp, DO-201","metaDescription":"Taiwan Semiconductor 1.5KE150CAHA0G bidirectional Zener TVS, 1500W peak pulse, 207V clamping, AEC-Q101 qualified.
