The 1.5SMC180CA/TR13: The 171 V minimum breakdown voltage ensures the avalanche triggers before the clamping event.
DO-214AB (SMC) — surface-mount integration
Housed in the DO-214AB (SMC) package, this TVS is a standard surface-mount footprint for power-supply and signal-line protection. The tape-and-reel packaging (TR) alongside cut-tape (CT) options means it feeds into automated pick-and-place lines without manual handling — the reel quantity is the usual procurement unit for volume builds.
YAGEO lists the 1.5SMC180CA/TR13 as Active in production. The part carries no power-line protection claim — it is a general-purpose TVS for signal and low-power rail protection, not for mains or high-energy AC line clamping.
