The S12571 series are general-purpose MPPC with drastically reduced afterpulses compared to our previously marketed

products. By widening the operating voltage range and improving the time resolution and photon detection efficiency, the

S12571 series offer the characteristics needed for a variety of applications. These MPPCs have a photosensitive area of 1 × 1

mm and are available in a ceramic package or surface mount type.

When an MPPC detects photons, the output may contain spurious signals appearing with a time delay from the light input to the MPPC.

These signals are called afterpulses. Compared to our previously marketed products, the S12571 series have drastically reduced afterpulses

due to use of improved materials and wafer process technologies. Reducing afterpulses brings various benefits such as a better S/N, a

wider operating voltage range, and improved time resolution and photon detection efficiency in high voltage regions.
