The bidirectional channel means a single device clamps both polarities, saving board space over back-to-back unidirectional parts. ## Breakdown and clamping — what the numbers mean for the rail Minimum breakdown voltage is 20.9 V, so the device starts conducting above that level. The 18.8 V reverse standoff is the maximum DC or peak AC voltage the TVS can sit across without significant leakage — a 24 V nominal rail with 5 % tolerance sits at 25.2 V, which exceeds this standoff, so this part suits a regulated 24 V bus with tight tolerance or a 12 V rail with margin. Clamping at 30.6 V means the protected circuit sees no more than that during a surge event. For a downstream DC-DC converter with a 36 V abs-max input, this provides adequate headroom. The DO-214AB (SMC) package with surface-mount mounting suits reflow assembly and keeps the thermal path through the solder joint to the PCB copper.","metaTitle":"1.5SMC22CA-M3/57T Vishay TVS, 1500W, 18.8V Standoff","metaDescription":"Vishay 1.5SMC22CA-M3/57T bidirectional TVS diode, 1500W peak pulse, 18.8V reverse standoff, DO-214AB.
