Other Parts Discussed in Thread: SN65HVD1040A-Q1
I'm struggling to find a TVS Diode for the SN65HVD231 because the maximum voltage at its terminal is much lower than on other ICs!
Look at the Absolute Maximum Ratings of the SN65HVD231:
Now, for comparison, look at the Absolute Maximum Ratings of the SN65HVD1040A-Q1:
The CDSOT23-T24CAN, for instance, would be a great fit for this IC.
In my case, the only TVS I could find that I think would work with the SN65HVD231 is the SM712-TP:

Am I wrong in my reasoning? Huge thanks for anyone that looks into this!
