The 53.9 V clamping ceiling means a 12 V supply bus with a 33.3 V TVS sees the protected downstream components held below 54 V during a surge event. Bidirectional configuration (single channel) means the same device clamps positive and negative transients symmetrically, which is useful on AC-coupled signal lines or power rails that see reverse polarity faults. ## Automotive-grade package and sourcing The package footprint is standard for the 1500 W SMC family, so layout reuse across multiple TVS voltage variants is straightforward.","metaTitle":"1.5SMC39CAH TVS Diode, 1500W, 33.3V, DO-214AB, AEC-Q101","metaDescription":"Taiwan Semiconductor 1.5SMC39CAH bidirectional Zener TVS, 1500W peak pulse, 33.3V standoff, AEC-Q101 automotive grade.
