TIDM-BIDIR-400-12: Questions about the diodes for input hot lines and output hot lines

Part Number: TIDM-BIDIR-400-12

Hello, Teams,

Thank you for supporting me every time.

I’d like to know the diodes which are connected to input hot lines and output hot lines.

In the video, before inputting DC voltage to the converter, the introducer showed the diodes which are connected to input hot lines and output hot lines. I assume that they are used for backflow prevention of current. Is it correct? Is it necessary to use them?

Also, I’d like to know the kind of the diodes, such as SBD, the necessary electrical characteristics of them, such as rated voltage, and the information of the examples of the diodes, such as manufacturer part number.

I appreciate your kind supports.

Best Regards,

Takumi

    This would be be my assumption as well. My guess is that diodes are used because of the bidirectional capability of the design. The diodes ensure that the HW doesn't drive power back into the DC source by mistake. I think it's a safety feature you should use as well.

    This information I do not have. The only information available is what is provided in the video.

    Dear Gus,

    Thank you for replying so many times.

    Based on your answer, I’d like to investigate and choose these diodes.

    Thank you for everything.

    Best Regards,

    Takumi
