TPD7S019: Reverse Standoff Voltage

Part Number: TPD7S019

Hey Team,

What is the reverse standoff voltage (VRWM) for the TPD7S019? It is mentioned in section 8.2.2 of the datasheet, but I don't see it in the electrical characteristics table. 

Best Regards,

Casey 

  • Hey Casey,

    I will admit, the datasheet is not specific; but it does give 9V as the minimum breakdown voltage for the ESD diodes on page 6 of the datasheet. As a result, the maximum reverse standoff voltage should be just under 9V, before any significant conduction occurs.

    Thanks,
    Thomas A.

    Thomas,

    The 9V spec is listed for the VIDEO pins. Is it the same for the DDC and SYNC pins?

    Best Regards,
    Casey

    Casey,

    Let me verify with the team who previously supported these parts.

    Casey,

    The breakdown voltage is where the ESD diodes starts to go into avalanche mode so you will want to stay away from that.

    According to Section 8.2.2 it says to keep those signals below the recommended operating condition (5.5V for VIDEO, DDC, and SYNC) and the ESD diodes will not turn on. Therefore I would call the 5V or 5.5V the VRWM (reverse working voltage)
