This paper presents the latest characterization results of a novel Low Cross-Talk (LCT) large-area (6 x 6-mm(2)) Multi-Pixel Photon Counter (MPPC) detector manufactured by Hamamatsu, belonging to the recent LCT5 family and achieving a fill-factor enhancement and cross-talk reduction. In addition, the newly adopted resin coating is demonstrated to yield improved photon detection capabilities in the 290350 nm spectral range, making the new LCT MPPC particularly suitable for emerging applications like Cherenkov Telescopes. For a 3 x 3-mm(2) version of the new MPPC under test, a comparative analysis of the large pixel pitch (75-mu m) detector versus the smaller pixel pitch (50-mu m) detector is also undertaken. Furthermore, measurements of the 6 x 6-mm(2) MPPC response versus the angle of incidence are provided for the characterized device.
