Is there available data on the ESD diodes used in the OPA2333? I have a circuit that will see a very high transient voltage, and I would like to create survivability metrics for this component. I-V curve data for the ESD diodes would be sufficient.

Jason,
Your protection circuit against OPA2333 high transient input voltages, Vin_max, must to based on the Absolute Maximum Ratings specification allowing maximum input current of 10mA - see below. This is typically accomplished by adding appropriately sized input resistor, Rin, in series with the input terminal: Rin=(Vin_max-Vcc-0.3V)/10mA.
