The 1.5SMCJ100CA: The reverse standoff of 100 V defines the working voltage the diode presents in normal operation — above it, the device enters conduction. At 162 V maximum clamping, the protected rail gets roughly 60% voltage headroom above the 100 V standoff — enough to absorb inductive kick and lightning-surge transients without propagating a damaging overvoltage to sensitive ICs downstream.
The listing classifies it as a Zener type; functionally it operates as a bidirectional TVS diode, clamping transients in both polarities across the single bidirectional channel.
