The 1.5SMCJ20CA_R1_00001: The 20 V reverse standoff (typ) is the working voltage — the TVS sits across the rail in the off state, drawing only leakage current. For a 20 V rail, the 12.4 V headroom between standoff and clamping ceiling gives the protected circuit room to ride out ESD or inductive transients without the TVS crowbarring the rail to ground under normal operation.
It is a Zener-based bidirectional TVS diode in the 1.5SMCJ series, packaged as an SMC (DO-214AB) surface-mount part. The Zener-type designation means the clamping action is voltage-driven — it snaps into conduction above the breakdown threshold, protecting the rail by clamping the surge to 32.4 V maximum.
