Product details

1500 W peak pulse power for automotive transient protection

The 1.5SMC30AHE3/9AT: That 1.5 kW rating means it absorbs load-dump and inductive-switch transients common in 12 V and 24 V automotive electrical systems without failing short.

Clamping voltage and breakdown tolerance

This clamping ceiling determines the voltage stress the downstream components must survive. The supplier device package is listed as DO-214AB (SMCJ), which is the same JEDEC outline — no footprint change between the two designations.

AEC-Q101 qualification and automotive deployment

The AEC-Q101 qualification and Automotive series designation mean the part has passed the stress tests (HBM ESD, temperature cycling, high-temperature reverse bias) required for under-hood and cabin electronics. The operating temperature range of -65°C to 150°C covers the full automotive thermal profile, from cold crank to engine-bay soak.
