SM6T22AY Description

Short technical summary and product information.

The SM6T22AY is a 600W peak pulse power Zener unidirectional TVS diode designed for automotive applications. It provides transient voltage protection with a reverse standoff voltage of 18.8V and a maximum clamping voltage of 30.6V at 102A peak pulse current (8/20µs waveform).

 

This device is surface mount packaged in a DO-214AA (SMB) case, enabling compact PCB layout. It operates over a temperature range of -55°C to 150°C (junction) and is rated for a minimum breakdown voltage of 20.9V. The diode is not intended for power line protection.

 

As an automotive-grade component, the SM6T22AY is suitable for use in vehicle electronics requiring robust transient suppression. The SMB package offers a good balance of power handling and board space.
