What the 1500 W peak pulse rating means for a 111 V rail
The 1.5SMC130AH: On a 111 V nominal rail, the device clamps at 179 V maximum at the rated 8.7 A peak pulse current — this is the voltage the downstream silicon sees during a surge event, not the rail itself.
Automotive qualification and deployment context
The -55°C to 150°C junction temperature range covers under-hood and engine-bay environments where ambient heat plus self-heating from surge events must stay within the die's thermal budget. Listed applications include Telecom, but the AEC-Q101 grade makes it equally suited for automotive power distribution, ECU input protection, and 12 V/24 V battery-line clamping where reliability screening is non-negotiable.
Housed in the DO-214AB (SMC) package, a standard surface-mount footprint with a copper tab on the cathode side. No power-line protection feature; this is a dedicated transient clamp for signal or DC power rails.
