Product details

Automotive qualification and temperature range

The 1.5SMC47AHM3_A/H: This part carries AEC-Q101 qualification — the automotive discrete semiconductor stress test that covers temperature cycling, high-temperature reverse bias, and humidity reliability. The unidirectional single-channel design (one Zener die) means it protects one signal or power rail per device. Power line protection is not listed as supported — this is a signal or low-power rail TVS, not a mains surge suppressor.

Confirm the full suffix matches your BOM line before committing.
