OPA659:Regarding the Input and ESD Protection of the OPA659

Part Number: OPA659

Tool/software:

The absolute maximum rating for the input voltage of the OPA659 is ±Vs.

According to "8.2.1 Input and ESD Protection" on the datasheet, there is a protection diode at the input to prevent voltages above Vs + Vf from being applied.

Even if there is a protection diode, a voltage that is Vf greater than the rated voltage will be applied to the input. Is this ok? If it is applied for an extremely short period of time, like ESD, is it ok?

Please let me know the value of Vf and how long it is okay to exceed the rated value without any problems.
