I am working with the SensL MicroFJ-60035-TSV photomultiplier. A link to the product can be found below:
I'm trying to develop models with it using LTspice in order to model a first-stage amplifier circuit with it, but I'm not sure how to best model it with basic components. Right now, I'm using the following circuit as a model; I tried to roughly model it around one for a diode, since this essentially functions similar to one.
The thing is, I never worked with photomultipliers before, so I don't really understand what the deal is with dark current, breakdown voltage, etc. Is this the best way to roughly model a photomultiplier? What can I do to make the model more accurate given the specifications?
UPDATE: I did some research, and I found a proposed SPICE model for silicon photomultipliers. The model can be found in the link below:
This seems like a useful model with which I can roughly model my designs, but I don't know how to model the various components from the datasheet alone. Components such as the quenching resistor and capacitor, the junction capacitance and the internal resistance, how can we extrapolate these values from the datasheet?
