These photodiodes are packaged in the Tray to protect them from damage. The photodiodes are put into Die packages for safety protection. In reverse-bias mode on a continual basis, the maximum amount of voltage the photodiodes can withstand is 25V. The voltage for the photodiodes should not exceed 25V in reverse-bias mode on a continual basis. Even in the absence of light input, a photodiode occurs 25nA current.
