The aim of this work is to provide the characteristics of MPPC arrays with an active area of 6x6 mm 2 in gamma-ray spectrometry with 5x5x5mm 3 CsI:TI scintillator at a wide temperature range. The measurements presented in this work covered: characteristics of breakdown voltage, selection of MPPC optimum operating voltage, verification of excess noise factor, measurement of energy resolution and the number of photoelectrons per 1 MeV. All measurements were carried out as a function of temperature and compared with similar results obtained previously with CsI:TI crystal coupled to a Large Area Photodiode (LAAPD).
