The photodiodes are packaged in the Tube in order to prevent damage to them. For safety reasons, the photodiodes are packaged in 2-DIP (0.213, 5.40mm) packages. It is considered that the maximum voltage the photodiodes can withstand in reverse-bias mode is 32V. When the photodiodes are reverse-biased, the voltage should never exceed 60V. There are 2 pins on the photodiodes. During the operation of a circuit, photodiodes can release 150mW heat. A photodiode should not operate at a temperature higher than 100°C. In spite of this, the photodiodes should be operated at a minimum operating temperature of -40°C. For photodiodes, the reverse anode voltage should be 32V. It is generally recommended that the maximum heat released by photodiodes should be 150mW in a circuit. If the reverse voltage is set to 32V, the photodiodes can work effectively. A photodiode must be operated at 1.3V to carry current. Make sure photodiodes work with 60V breakdown voltage. There is 2nA current flowing through a photodiode even in the absence of light input.
