  • Wide receiving angle
  • Linear response vs. irradiance
  • Fast switching time
  • Side-looking package ideal for space limited applications De scrip tion The OP950 device consists of a PIN silicon photodiode molded in a clear epoxy package which allows spectral response from visible to infrared light wavelengths. The wide receiving angle provides relatively even reception over a large area. The side-looking package is designed for easy PC board mounting. This photodiode is mechanically and spectrally matched to Optek’s GaAs and GaAlAs series of infrared emitting diodes. Ab so lute Maxi mum Rat ings (TA = 25o C un less oth er wise noted) Lead Sol der ing Tem pera ture [1/16 inch (1.6 mm) from case for 5 sec. with sol der ing 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.
