Photodiodes are enclosed in Tape & Reel (TR) to prevent damage. It is necessary to place the photodiodes into SMD/SMT packages in order to protect them from damage. As long as the photodiodes are operated continuously in reverse-bias mode, the maximum voltage they can tolerate is 60V. When the photodiodes are reverse-biased, the voltage should never exceed 60V. There are 2 pins on the photodiodes. Within a circuit, photodiodes may emit heat 75mW. Photodiodes should operate at a temperature of 85°C. There should, however, be a minimum operating temperature of -40°C for the photodiodes. Photodiodes should have a reverse anode voltage of 60V. A circuit should experience a maximum heat release of 75mW when photodiodes are used. If your DC circuit has a reverse voltage of 60V, the photodiodes will work properly. For a photodiode to operate, a voltage of 1V is required. In the absence of light input, a photodiode produces 1nA current.
