The 1.5SMC33A-E3/9AT: Reverse standoff voltage is 28.2 V typical, with a breakdown range starting at 31.4 V minimum — the device stays transparent below the working voltage and starts conducting only when the line exceeds the breakdown threshold.
It uses the DO-214AB (SMC) surface-mount package, also referred to as the SMCJ footprint, with a large copper tab for thermal management.
