  Silicon Photo-Multipliers (SiPMs) are semiconductor-based photo-detectors
with performances similar to the traditional Photo-Multiplier Tubes (PMTs). An
increasing number of experiments dedicated to particle detection in colliders,
accelerators, astrophysics, neutrino and rare-event physics involving
scintillators are using SiPMs as photodetectors. They are gradually
substituting PMTs in many applications, especially where low voltages are
required and high magnetic field is present. Hamamatsu Photonics K.K., one of
leading producers of photo-detectors, in the last year introduced the S14160
series of SiPMs with improved performances. In this work, a characterization of
these devices will be presented in terms of breakdown voltages, pulse shape,
dark current and gain. Particular attention has been dedicated to the analysis
of the parameters as function of temperature.
