Description
These TVS diodes are supposed to protect the 3.3V at the HARP Aux port.
- D1 in rp2040_with_usb
- D4 in isolated_usb_rp2040
The linked datasheets for the diodes indicate the standoff voltage is 5.3V, but they should be close to 3.3V? I'm not sure they're the actual TVS diodes you end up using though, their Value field doesn't have a MPN. Also, the datasheet linked for TVS diodes in the schematic is for discontinued TVS diodes, another reason to believe you don't actually use the TVS diodes from the datasheet in the KiCAD symbol. It's not too much of an issue, but thought I'd mention it anyway just in case
