Hi,
I´m looking for the right parameters to select a good TVS diode for the SWD pins of an nRF53-based circuit. The processor is powered by 1.8 V, so according to the datasheet, the maximum IO voltage is 2.1 V. For this I have selected one of those diodes:

Do they fit or can I use a higher voltage?
