OPA320: How to set the parameters of current source in TINA software to simulate the Si Photodiode

Harrison Wang
Intellectual 280 points
Part Number: OPA320


We use the TINA software to simulate the reference design TIDU535(www.ti.com.cn/.../tidu535.pdf).But we choose the Si Photodiode(HAMAMATSU S1227 series) as the input signal source.

We want to know whether the Photodiode model contain the P/N of Si Photodiode？If not,how to set the parameters of current source in TINA software to simulate the Si Photodiode？

The Spec of the Si Photodiode:

    Hi Harrison,

    To test DC response of the photodiode circuit, you will sweep the current source (IPD) from the dark current value (ID) up to the short-circuit current value in the table above. The junction capacitance (CJ) should be set to the terminal capacitance from the table above.
