SMA6T68CAY Description

Short technical summary and product information.

The STMicroelectronics SMA6T68CAY is a bidirectional TVS diode designed for transient voltage suppression in automotive applications. With a reverse standoff voltage of 58.1V and a clamping voltage of 121V, it provides protection against high-energy transients. The device is rated for 600W peak pulse power at 8/20µs pulse shape, with a peak pulse current handling capability of 33A. Its Zener technology ensures fast response to overvoltage events. Operating over a junction temperature range of -40°C to 150°C, it is suitable for harsh automotive environments. The SMA6T68CAY is offered in a surface-mount DO-214AC (SMA) package, which is compact and suitable for automated assembly. The part is RoHS compliant and REACH unaffected, meeting environmental standards for electronic components.
