TPD4E05U06 connected in serial

Other Parts Discussed in Thread: TPD4E05U06

Hi,

In my application I need to protect my circuit (RS422 serial communication at ~10MSPS and SSR that has isolated contact from all grounds) from IEC61000-4-2 (ESD), IEC61000-4-4 (EFT) and IEC61000-4-2 (Surge). For that purpose, I select the TPD4E05U06 IEC ESD device. Can I connect this device in serial one to another? (One will protect the SSR contact in parallel and one will protect the communication, also in parallel. The current rout is from the source, through D1, through D2 and to ground- and backward when negative surge)

Thanks,

Idan
