The 30.6 V clamping voltage at 49 A peak pulse current limits the voltage seen by the downstream ICs during a transient event. For a 24 V system with a 36 V load-dump clamp target, this TVS holds the line below the abs-max of most 40 V-rated ECUs and sensors. ## DO-214AB footprint and surface-mount assembly No power line protection feature is implemented — this is a unidirectional transient suppressor for signal or low-side power rails, not an AC mains protector.","metaTitle":"Vishay 1.5SMC22AHE3/9AT TVS, 1500W, 18.8V, DO-214AB","metaDescription":"Vishay 1.5SMC22AHE3/9AT Zener TVS, 1500W peak pulse, 18.8V standoff, AEC-Q101, DO-214AB.
