Leaded Logic Output Photodetector

Product type Ee+ (mW/cm@) @ 880nm typ VOL (V) max Reception angle @ half intensity (Deg) Output
QSE258 0.25 0.4 50 Buffer Open Collector


  • Sidelooker package
  • High Noise Immunity
  • Buffer Open Collector
  • Reception Angle 50°
  • RoHS compliant


The device consists of a photodiode, a linear amplifier, a voltage regulator, a Schmitt trigger and an open collector output transistor. The Schmitt trigger provides hysteresis for noise immunity and pulse shaping. The open collector output allows interfacing with various logic level circuits. Packaged in a leaded sidelooker package with daylight filter.
