TS3A4751: max. current Rating for internal diodes on COM/NO

Part Number: TS3A4751

Hello,

in the datasheet on page 4 is the following footnote "Signals on COM or NO exceeding VCC or GND are clamped by internal diodes. Limit forward diode current to maximum current Rating."

I do have higher voltages than Vcc on COM/NO and want to limit the current with a restistor, but I can not find the maximum current rating for the internal diodes.

 

Thanks a lot in advance, Jan

  • Hi, Jan,

    The internal ESD diodes used in this process technology typically has maximum rated current rating of 50mA. We would recommend keeping maximum current below 30mA just to have a little bit of buffer.

    Thanks,
    David
