TVS protection rating and what the clamping figure means
The 1.5SMC82AHM6G: The standoff voltage of 70.1 V defines the normal operating rail it protects without clamping; when a transient exceeds the 77.9 V breakdown threshold, the device avalanche-avenges and clamps the peak current of 13.9 A to a maximum of 113 V across the protected node.
Surface mount footprint and assembly notes
The DO-214AB SMC is a standard automotive pad footprint — the cathodes bar aligns to the polarity marking. The Tape & Reel packaging is standard for high-volume assembly pick-and-place. No through-hole rework needed; hot-air rework at the SMC body follows the normal reflow profile, and a pre-bake before rework is good practice given the moisture sensitivity of the package — confirm the MSL rating against the assembly floor-life budget.
