  We characterized the S13360-3050CS Multi-Pixel Photon Counter (MPPC), a
silicon photomultiplier (SiPM) manufactured by Hamamatsu Photonics K.K..
Measurements were obtained inside a light tight dark box using 365 nm, 400 nm,
525 nm, 660 nm, 720 nm, 810 nm, and 900 nm light-emitting diodes (LED) and the
Citiroc 1A front-end evaluation system manufactured by Weeroc. At a 2.95V over
voltage, we measured a dark count rate of 5.07x$10^{5}$ counts per second at
26$^{\circ}$C, crosstalk probability of 8.7$\%$, photon detection efficiency of
36$\%$ at 400 nm, linear range of 1.8x$10^{7}$ photons per second, and
saturation at 5x$10^8$ photons per second. The S13360-3050CS MPPC is a
candidate detector for the Ultra-Fast Astronomy (UFA) telescope which will
characterize the optical sky in the millisecond to nanosecond timescales using
two SiPM arrays operated in coincidence mounted on the 0.7 meter Nazarbayev
University Transient Telescope at the Assy-Turgen Astrophysical Observatory
(NUTTelA-TAO) located near Almaty, Kazakhstan. One objective of the UFA
telescope will be to search for optical counterparts to fast radio bursts (FRB)
that can be used to identify the origins of FRB and probe the epoch of
reionization and baryonic matter in the interstellar and intergalactic mediums.
