Phototransistor arrays

The monolithic phototransistor arrays are available with 4, 6 or 13 elements and small optical pitches of 0.6 mm or 0.45 mm. The active area of each element is 0.2 mm x 0.45 mm or 0.25 mm x 0.50 mm. The devices features high uniformity of the silicon sensors, high signal stability and high optical responsivity. The small SMD plastic packages offer two reference marks for precise collimator positioning.

Typical applications of the phototransistor arrays include optical encoders, incremental encoders, optical receivers and controls/drives.

Special features
  • High uniformity
  • High gain
  • High transparency and very robust encapsulant
  • Very small dimensions
  • Reference marks for very precise mounting
  • RoHS compliant
