AMC3330-Q1: Surge protection for IC

Part Number: AMC3330-Q1
Other Parts Discussed in Thread: AMC3302, AMC3330, TINA-TI, AMC1300


For Line-to-Line voltage measurement, we are using AMC3330-Q1 IC. We have referred a TI application note, where the low voltage end IC is used for voltage measurement and their diodes are used for surge protection. Similarly we have used diodes for surge protection in our application where we have used AMC3330-Q1 IC (please refer below image). Please confirm if we can use diodes for surge protection for AMC3300-Q1 IC and also please inform if AMC3330-Q1 IC has any internal surge protection feature.
