1500 W peak pulse — bidirectional clamping for 25.6 V rails
The 1.5SMC30CA-M3/57T: Reverse standoff voltage is 25.6 V, meaning a 24 V nominal rail stays below the leakage threshold during normal operation; breakdown occurs at 28.5 V minimum, providing a 2.9 V guard band before the TVS enters avalanche.
DO-214AB — surface-mount footprint for reflow assembly
Single bidirectional channel means one part protects a signal pair or a differential line without needing two unidirectional devices back-to-back — a BOM simplification for 24 V sensor interfaces or CAN bus transceivers.
