Using two devices sounds a bit messy but if you try it let us know how it goes.
My thoughts on the USB3 device is it is very low capacitance and actually has a superior protection strategy in using ordinary diodes combined with a clamp diode so that the higher capacitance of clamp diodes is effectively shielded by the low capacitance ordinary diodes.
It is in a smaller pack which may make it a bit fiddly to fit. I’m not overly concerned about any differences in protection voltage as the series limiting resistor will lower fault current levels that could possibly get to the actual device before the main protection kicks in.
I’ve ordered one to give it a go.
