SM6T12CAY Description

Short technical summary and product information.

The SM6T12CAY is a bidirectional Zener TVS diode designed for transient voltage suppression in automotive electronics. Rated for 600W peak pulse power (8/20µs waveform), it provides reliable clamping up to 21.7V at the peak pulse current of 184A. With a reverse standoff voltage of 10.2V, it protects sensitive circuits from voltage spikes.

 

This surface-mount device is housed in a DO-214AA (SMB) package, supporting operating temperatures from -55°C to 150°C. It is not intended for power line protection but is optimized for signal and I/O line protection. The component meets automotive application requirements and is designed for high-reliability environments.

 

The SM6T12CAY is RoHS3 compliant, REACH unaffected, and has an MSL rating of 1 (unlimited), ensuring ease of handling and assembly. Its compact SMB footprint makes it suitable for space-constrained designs in automotive ECUs, infotainment systems, and sensor interfaces.
