PM66 in SMD package


Active area 6 x 6 mm2 - 25 µm or 50 µm microcell type
Silicon Photomultiplier in chip size package for single photon detection

The KETEK PM6625 and PM6650 are due to their balance between high geometrical efficiency and numbers of micro pixels a wide application field sensor.


  • Single photon counting
  • High photon detection efficiency
  • Optimized for blue light
  • High gain and excellent timing properties
  • Low dark count rate and low cross talk probability
    especially for trench type
  • Huge bias voltage range of stable operation
  • Extremely low temperature coefficient
