Body Diode Clamping Current

[d.stracke]

Ladies and Gentlemen,

I was wondering about the maximum clamping current of the Body Diodes of the nRF9160's IOs.
There is no value stated in the product specification.
I'm trying to decide on a current limiting resistor for ESD input protection on some of the IOs and therefore I need such a value.

Best regards,

Hello,

  

I was wondering about the maximum clamping current of the Body Diodes of the nRF9160's IOs.

This is correct, we do not specify the properties of the clamping diodes, but rather explain the operating conditions you should be within.

The ratings of the device can be found in this chapter of the PS:

If you exceed the voltages described in the above maximum ratings, you should use external components to be within the nRF9160's specification.

 

Kind regards,

Håkon
