The operating junction temperature range spans -55°C to 175°C, covering the full automotive temperature envelope including cold-crank and engine-bay heat soak. ## Package and board integration The part is unidirectional with a single cathode-band marking—confirm the polarity orientation matches the protected rail. Power line protection is not supported; this is a signal or DC-bus clamp, not an AC mains suppressor. ## Sourcing and compliance posture Listed as Active by Taiwan Semiconductor Corporation. The 1.5KE series includes other voltage variants, but a parametric substitute would require verifying the standoff and clamping levels match the circuit's protection threshold.","metaTitle":"1.5KE120AH TVS Diode, 1500W, 102V Standoff, DO-201, AEC-Q101","metaDescription":"Taiwan Semiconductor 1.5KE120AH Zener TVS, 1500W peak pulse, 102V reverse standoff, AEC-Q101 automotive grade.
