I was wondering how to effectively read a photodiode datasheet. Leds have max current ratings and voltage drops clearly listed but the photodiode one confuses me.
Im trying to calculate a resistance value to add in series with it but am unsure.
I see light current, dark current, and some have forward voltage and some have just reverse on the datasheets, so I am really confused.
I just want my photodiode to be most sensitive to changes in light.
Using this PD
I wanted to drive it with 5V supply.
I just tested it with the photodiode in series with a resistor to give its light current rating. I measure the voltage across the photodiode and it changes with more light, but I thought the voltage is supposed to stay constant im confused. Is there a problem with my current setup?
