Photodiodes are enclosed in Tape & Reel (TR) to prevent damage. Photodiodes are packaged in 2-SMD, Z-Bend packages in order to ensure their safety. When reverse-biased, the photodiodes should not continually exceed 32V. Photodiodes have pins 2. An ideal circuit would allow the photodiodes to release a maximum amount of heat in the form of 150mW heat. A reverse voltage 32V does not affect the photodiodes in the DC circuit. There is 5nA current flowing through a photodiode even in the absence of light input.
