These photodiodes are packaged in the Tray to protect them from damage. The photodiodes are put into SMD/SMT packages for safety protection. In reverse-bias mode on a continual basis, the maximum amount of voltage the photodiodes can withstand is 50V. The voltage for the photodiodes should not exceed 50V in reverse-bias mode on a continual basis. The photodiodes have 12 pins. The temperature should not be higher than 125°C when photodiodes operate. But the minimum operating temperature for the photodiodes should be set to -55°C. In the reverse-bias mode, the photodiodes could supply 50V voltage. Even in the absence of light input, a photodiode occurs 5μA current.
