SMA6T28CAY Description

Short technical summary and product information.

The SMA6T28CAY is a 600W automotive-grade Zener transient voltage suppression (TVS) diode from STMicroelectronics, designed to protect sensitive electronics from voltage transients. It offers a reverse standoff voltage of 24V and a maximum clamping voltage of 44.3V at 80A peak pulse current (8/20µs waveform).

 

The device is housed in a compact DO-214AC (SMA) surface mount package and operates over a junction temperature range of -40°C to 150°C. It is a unidirectional or bidirectional single-channel device, depending on configuration, and does not include power line protection.

 

This TVS diode is intended for automotive applications, including protection of electronic control units, sensors, and infotainment systems from load dump and other transients. The SMA package is suitable for automated assembly in high-volume production.

 

RoHS3 compliant, REACH unaffected, with MSL 1 unlimited moisture sensitivity level for simplified storage and handling.
