  • Non-Contact Position Sensing
  • Datum detection
  • Machine automation
  • Optical encoders OP520, OP521
  • High Photo Sensitivity
  • Fast Response Time
  • 1206 Package Size
  • Opaque or Water Clear Flat Lens Description: The OP520 and OP521 are NPN silicon phototransistor mounted in miniature SMT packages. Both the OP520 and OP521 have a flat lens however, the OP520 lens is opaque to shield the device from stray light. These sen- sors are packaged in 1206 size chip carriers that are compatible with most automated mounting equipment. The OP520 and OP521 are mechanically and spectrally matched to the OP250 series infrared LEDs.

SMD Silicon Phototransistor OP520, OP521 Absolute Maximum Ratings TA = 25o C unless otherwise noted Storage Temperature Range -40° C to +85° C Operating Temperature Range -25° C to +85° C Lead Soldering Temperature 260° C(1) Collector-Emitter Voltage 30 V Collector Current 20 mA Power Dissipation 75 mW(2) Emitter-Collector Voltage 5 V Notes: 1. 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 emission 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 dark current in µA, use the formula I CEO = 10(0.04Ta-3.4) where Ta is the ambient temperature in ° C.
