1500 W peak pulse — what that means on a surge
The 1.5SMC160CA TR13 PBFREE: The 6.8 A peak pulse current tells you the surge it can sink before the junction gives up. Because it is bidirectional (one channel), a single device protects both polarities on a signal or DC rail — no need to series two unidirectional parts. The breakdown triggers at 152 V minimum, so the protected rail stays below that until the transient hits.
DO-214AB SMC — board-fit and environment
Surface-mount in the DO-214AB (SMC) package, the same footprint used across the 1.5SMC family. The -65°C to 150°C junction temperature range covers cold-soak start and hot reflow without derating the pulse capability. No power line protection rating means this part is intended for signal, data, or low-voltage DC rail clamping — not for AC mains or high-energy industrial bus suppression.
