    Hello Beida,

    There is no TVS in this image. I recommend to read the difference between TVS and Zener diodes online to get an idea on how they differ.

    There is no Zener/10-Meg on DSG because we did not believe these are necessary as we do not expect high transients here.

    Best Regards,
