Product details

1500W automotive TVS — what the ratings mean on the bench

The 1.5SMC30AHR7G: The 28.5V minimum breakdown voltage means this part starts conducting between 28.5V and the typical 31.5V range — it protects a 24V nominal rail from load-dump or inductive kickback without clipping the normal operating envelope.

Package and board-fit for the DO-214AB SMC footprint

Surface-mount DO-214AB (SMC) package — the same footprint as standard SMC diodes, so the board layout is interchangeable with other 1500W TVS parts in this case size.

Frequently asked questions

What voltage rail does 1.5SMC30AHR7G protect?

With a 25.6V reverse standoff and a 28.5V minimum breakdown, this TVS is sized for 24V nominal DC rails — common in automotive, industrial control, and telecom power buses. It clamps at 41.4V maximum under a 38A peak pulse.

What compliance documentation is available for 1.5SMC30AHR7G?

The part carries AEC-Q101 automotive qualification.
