Two Hamamatsu Photonics silicon photomultipliers (SiPM) with same cell size 50×50 µm2 and different sensitive area (1×1 mm2 vs. 3×3 mm2) have been characterized in charge and time by means of a 409 nm pico-laser. The time resolution was studied for the detection of few photoelectrons. The results obtained are relevant for the employment of SiPM in ring imaging Cherenkov detectors (RICH).
