To prevent damage to these photodiodes, they are packaged in Tray. For safety reasons, the photodiodes are packaged in Die packages. As long as the photodiodes are operated continuously in reverse-bias mode, the maximum voltage they can tolerate is 25V. A continuous reverse-bias voltage of 25V should not be exceeded by the photodiodes. When no light is input, a photodiode will conduct at 6nA current.
