The 1.5SMC480AHE3_A/I: Sourced through independent distribution against an RFQ.
For a 408V standoff voltage (reverse standoff typ), the clamping voltage at peak pulse current is 658V max, limiting the voltage seen by downstream components. The part is a Zener-type TVS with a single unidirectional channel, so it clamps positive transients relative to ground.
Qualified to AEC-Q101, the automotive discrete semiconductor reliability standard.
A functionally equivalent TVS with the same DO-214AB package and similar standoff/breakdown/clamping voltages would need to be selected from current-production parts; the BOM position may require re-qualification.
