Notes:
(1) RMA flux is recommended. Duration can be extended to 10 sec. max. when flow soldering.
Max. 20 grams force may be applied to leads when soldering.(2) Derate linearly 1.67 mW/o C above 25o C.
(3) Light source is an unfiltered GaAs LED with a peak emission wavelength of 935nm and a
radiometric intensity level which varies less than 10% over the entire lens surface of thephotodiode being tested.
(4) To calculate typical dark current in µA, use the formula ID = 10(0.042 TA-1.5) where TA is
ambient temperature in o C.
Description
The OP955 devices consists of a PINsilicon photodiode molded in a clearepoxy package which allows spectralresponse from visible to infrared
wavelengths. The wide receiving angleprovides relatively even reception over a
