The 1.5SMC47AS_R1_00001: Clamping at 64.8 V maximum at the 23.2 A peak pulse current limits the transient voltage the downstream ICs see.
The wide-body SMC copper tab under the cathode end sinks pulse heat into the board copper — the thermal impedance is set by the pad area, not the package itself.
Type is Zener (unidirectional TVS), package is DO-214AB (SMC) surface mount, supplied on Tape & Reel or Cut Tape.
