PA1125 0808 groupIndividual Silicon Photomultipliers and each SiPM in an array can be tested to confirm they are functioning as a "diode" - although in the case of SiPMs we are actually testing a large array of microcells - each of which is a photodiode.


Equipment Required:


  • Silicon Photomulitplier or SiPM array
  • Data sheet for Device Under Test (DUT)
  • Digital multimeter




  • Place DUT sensitive side down to access BGA, leads or connector
  • Set multimeter to "Diode Check" setting
  • Apply Black lead of multimeter to Cathode of SiPM
  • Apply Red lead of multimeter to Anode of SiPM
  • A reading of ~0.6V indicates a diode is present
