TINA/Spice/OPA4171: OPA171 back to back diode issue

Part Number: OPA4171
Other Parts Discussed in Thread: TINA-TI, , OPA171, TLV171

Tool/software: TINA-TI or Spice Models


Our customers found that OPA4171 can't operate normally in our application because of the back to back diode.

but we didn't find this problem in our TINA simulation result with OPA171 TINA spice model.

It seems like it doesn't model the back to back diode in OPA4171's model.

Can you offer the modified model with back to back diode

or please tell me how can I model these diodes externally(like forward voltage drop=?...)

Thank you very much!!
