MPPC® (multi-pixel photon counter) S12572-025, -050,-100C/P Low afterpulse, for general measurement Photosensitive area: 3 × 3 mm The S12572 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 S12572 series offer the characteristics needed for a variety of applications. These MPPCs have a photosensitive area of 3 × 3 mm and are available in a ceramic package or surface mount type. Features Applications Significantly reduced afterpulses (compared to previous products) Fluorescence measurement Superior photon counting capability (superior photon detection efficiency against incident photons) DNA sequencer Flow cytometry Compact Environmental analysis PET Operates at room temperature High energy physics experiment Low voltage (100 V or less) operation High gain: 105 to 106 Related product (sold separately) Superior time resolution Immune to the effects of magnetic fields MPPC module C11205-350 Operates with simple readout circuits MPPC module also available (sold separately) Low afterpulse 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 S12572 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.

The 25 μm pixel pitch type is suitable for applications requiring a wide dynamic range, because it has a large number of pixels and provides narrow-width output pulses. The 100 μm pixel pitch type is suitable for applications where high gain is essential. Although increasing the operating voltage improves the photon detection efficiency and time resolution, it also increases the dark count and crosstalk at the same time, so an optimum operating voltage must be selected to match the application. 4 MPPC (multi-pixel photon counter) S12572-025, -050, -100C/P Dimensional outlines (unit: mm) S12572-025C/-050C/-100C S12572-025P/-050P/-100P 4.35 6.55 ± 0.15 1.45 ± 0.15 0.925 ± 0.15 Photosensitive area 3.0 × 3.0 3.85 * Photosensitive surface 0.33 Photosensitive area 3.0 × 3.0 Epoxy resin 1.0 4.25 1.0 Epoxy resin 2.2 2.0 ± 0.2 0.45 ± 0.15 0.3 0.425 ± 0.15 5.9 ± 0.15 * Index mark ɸ0.2 * Tolerance unless otherwise noted: ±0.1 6.0 ± 0.5 Photosensitive surface 2.54 ± 0.15 0.46 Lead (2.0) KAPDA0144EA Tolerance unless otherwise noted: ±0.2 * Metal electrodes connecting to the internal electrodes are exposed on the sides of the ceramic package.
