Individual 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
Procedure:
- 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
