https://devzone.nordicsemi.com/f/nordic-q-a/76355/body-diode-clamping-currentLadies and Gentlemen, I was wondering about the maximum clamping current of the Body Diodes of the nRF9160&#39;s IOs. There is no value stated in the product specification. I&#39;m trying to decide on a current limiting resistor for ESD input protection onen-USTelligent Community 13Tue, 15 Jun 2021 11:37:40 GMThttps://devzone.nordicsemi.com/thread/315365?ContentTypeID=1Tue, 15 Jun 2021 11:37:40 GMT137ad170-7792-4731-bb38-c0d22fbe4515:0ad1ca20-b3a9-45ae-955a-94f0240ad7b5H&#229;kon Alseth<p>Hello,</p> <p>&nbsp;&nbsp;</p> [quote user=""]I was wondering about the maximum clamping current of the Body Diodes of the nRF9160&#39;s IOs. <br />There is no value stated in the product specification.[/quote] <p>This is correct, we do not specify the properties of the clamping diodes, but rather explain the operating conditions you should be within.</p> <p>The ratings of the device can be found in this chapter of the PS:</p> <p><a href="https://infocenter.nordicsemi.com/topic/ps_nrf9160/abs_max_ratings.html?cp=2_0_0_11">https://infocenter.nordicsemi.com/topic/ps_nrf9160/abs_max_ratings.html?cp=2_0_0_11</a></p> <p>&nbsp;</p> <p>If you exceed the voltages described in the above maximum ratings, you should use external components to be within the nRF9160&#39;s specification.</p> <p>&nbsp;</p> <p>Kind regards,</p> <p>Håkon</p><div style="clear:both;"></div>
