Product details

1500 W bidirectional TVS for 12 V automotive rails

The 1.5SMC11CAHE3/9AT: The AEC-Q101 qualification (Grade 1, -65°C to +150°C junction) confirms it for under-hood and engine-bay deployment where the ambient temperature regularly exceeds 105°C.

Clamping voltage and surge current — the fit decision

The 15.6 V maximum clamping voltage at 96.2 A peak pulse current defines the protection ceiling. For a 12 V nominal rail that can spike to 35 V during a load-dump event, this TVS holds the line below the 40 V abs-max rating of most automotive-grade buck converters and linear regulators. The 9.4 V standoff voltage means it does not leak appreciably at the normal 12 V operating level.

Listed as Active on the manufacturer's lifecycle record.
