The 1.5SMC24A-M3/57T: With a 20.5 V reverse standoff voltage, it sits below the rail without conducting during normal operation, and its 33.2 V clamping voltage limits the spike seen by downstream components during a surge event.
Within the same 1.5SMC TransZorb series, other voltage variants (e.g., 1.5SMC18A, 1.5SMC30A) share the identical DO-214AB footprint and pinout.
