ADM2587E TVS diode protection

I would like to know if the recommended TVS diode Bourns CDSOT23-SM712 (AN-1161) will provide protection from a short to power 24Volts DC.


We are using the ADM2587E IsoPower Isolated RS485 transceiver with Bourns TBU and TVS diode protection. From the datasheet the maximum driver input/output voltage range is -9 to 14 volts. The TVS diode has a minimum breakdown voltage of 13.3 volts. If there is a short to +24V is the TVS going to protect the transceiver?
