  • Optical encoders Silicon Phototransistor in Miniature SMT Package OP522
  • High Photo Sensitivity
  • Fast Response Time
  • 1206 Package Size with Internal Lens The OP522 is an NPN silicon phototransistor mounted in a miniature SMT package. The device incorporates an integral molded lens which enables a narrow acceptance angle and higher collector currents than devices without lenses. This device is packaged in a 1206 size chip carrier that is compatible with most automated mounting equipment. The OP522 is mechanically and spectrally matched to the OP250 series infrared LEDs. Optek reserves the right to make changes at any time in order to improve design and to supply the best product possible.

Solder time less than 5 seconds at temperature extreme. 2. De-rate linearly at 2.17 mW/° C above 25° C. 3. Light source is an unfiltered GaAs LED with a peak emissi on wavelength of 935nm and a radiometric intensity level which varies less than 10% over the entire lens surface of the phototransistor being tested. 4. To Calculate typical collector da rk current in µA, use the formula ICEO = 10(0.04 T A -3/4) where TA is the ambient temperature in ° C.
