I have a project that would use a USB C connector that would be used on a board that does not need USB power. (its an addon board for something)
I have copied this circuit from sparkfun:

except with this protection diode device.

my question is, when not using USB power do i connect the positive connector on the protection device to the USB power or to the power rail on my circuit, or do I even need the ESD protection with USB C? (this thing will be used by musicians, so it needs to be able to stand up to some oafish abuse)
