Hello,

Thank you for your question.

Our digital isolators support SPI communication and automotive applications, such as the ISO6741-Q1 and ISO7741-Q1.

For more information regarding using digital isolators for SPI, I highly recommend looking at Isolating SPI Signals (Rev. A)

Thank you for your response.

I need one more suggestion for Bust and surge which kind of protection circuit need to add for reducing the common mode noise in EMC environment

TI digital isolators I/O pins typically are not subjected to Burst and Surge tests directly, therefore they do not require protection circuits for their I/O pins.

If the surge or burst test is performed on interfaces like RS-485 or CAN bus, then a TVS diode or a Common-Mode-Choke can be used in order to protect the device. Please check these resources below for more information:

TIDA-00731 reference design | TI.com --- Protection for RS-485 bus
TIDA-00629 reference design | TI.com --- Protection for CAN bus
