MUX36D04: More robust ESD protection

Part Number: MUX36D04

Hello, 

I need help with a recommendation for addition ESD for a MUX36D04 design. 

The mux doesn’t appear to be particularly robust by itself, which is fine, but it will be subjected to up to 30 kV air/contact discharges, the latter going through a 1 Mohm 0805 resistor. Is there any TVS solution you can recommend to protect the MUX input, preferably something in a small package? 10 kV contact, 20 kV air is our minimum requirement, but 30 kV contact/air is preferred. The max operating voltage on the MUX input will be about 7V, and the signal is a DC voltage, so bandwidth (parasitic capacitance) doesn’t matter.

Thanks!
