Product details

Automotive-grade transient protection with AEC-Q101 traceability

The 1.5SMC47CAHR7G: The single bidirectional channel handles 24 A peak pulse current in the same waveform, so a single device covers both polarities on a signal or power line without series stacking.

Package and temperature envelope for board integration

The SMC footprint provides a large copper pad area under the cathode tab for thermal dissipation; the 1500 W rating assumes the standard JEDEC board layout with adequate copper pour.

Frequently asked questions

What does the AEC-Q101 qualification mean for this TVS diode?

AEC-Q101 certifies the device for automotive-grade reliability — it has passed temperature cycling, high-temperature reverse bias, and ESD sensitivity tests per the automotive discrete semiconductor standard. This makes it suitable for engine control units, transmission controllers, and battery management systems that require PPAP traceability.
