SM6T68AY Description

Short technical summary and product information.

The SM6T68AY is a Zener-type TVS diode designed for automotive applications. It offers a reverse standoff voltage of 58.1V and a maximum clamping voltage of 121V at 33A peak pulse current (8/20µs waveform). The device can handle 600W peak pulse power, making it suitable for transient voltage suppression in automotive electronics.

 

This TVS diode is not intended for power line protection; it is optimized for signal line protection in automotive systems. It features a single unidirectional channel and operates over a temperature range of -55°C to 150°C.

 

The SM6T68AY is supplied in a surface-mount DO-214AA (SMB) package, which is suitable for automated assembly. The supplier device package is SMB (DO-214AA).
