Hi Support Team 

Is it normal that nRF54L15-QFAA reset when air discharge 8KV? But nRF52 hasn’t this issue under the same conditions.Many thanks.

The ESD rating of this is 1kV, see https://docs.nordicsemi.com/bundle/ps_nrf54L15/page/chapters/abs_max_ratings/doc/abs_max_ratings.html

For levels above this, additional protection devices are needed.

Hi Ketiljo

We found a ESD problem on NRF54L10-QFAA, we used AD 8KV close to the USB, The MCU will reset, read the MCU status, it is nRESET pin reset. is there any idea on it. Many thanks?
