Where a unidirectional TVS in DO-214AB fits on the board
The 1.5SMCJ150CA: Surface-mount SMC/DO-214AB is the industry-standard package for 1.5–3 kW TVS devices — the same footprint accepts cross-licensed parts from multiple manufacturers, so single-source risk on this footprint is manageable. The part is classified for general-purpose applications — it is not qualified to automotive AEC-Q101, so a separate automotive grade would be needed for under-hood or cabin-domain use.
