The very wide receiving angle provides relatively even reception over a large area. The side-looking package is designed for easy PC board mounting. These devices are 100% production tested using infrared light for close correlation with Optek’s GaAs and GaAlAs emitters. 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 the photodiode 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.
