The S13361-3050 series is a MPPC array for precision measurement miniaturized by the use of TSV (through-silicon via) and CSP
(chip size package) technologies. The adoption of a TSV structure made it possible to eliminate wiring on the photosensitive area
side, resulting in a compact structure with little dead space compared with previous products. The four-side buttable structure
allows multiple devices to be arranged side by side to fabricate large-area devices.
They are suitable for applications, such as medical, non-destructive inspection, environmental analysis, and high energy physics
experiment, that require photon counting measurement.

Lower noise
When an MPPC detects photons, the output may contain spurious pulses, namely afterpulse and crosstalk, that are separate from the out-
put pulses of the incident photons. Afterpulses are output later than the timing at which the incident light is received. Crosstalk is output
from other pixels at the same time as the detection of light.
Previous products achieved lower afterpulse through the improvement of material and wafer process technology, but with the S13361-3050
series, low crosstalk has been achieved in addition to low afterpulse.

*2: No dew condensation
When there is a temperature difference between a product and the surrounding area in high humidity environment, dew condensation
may occur on the product surface. Dew condensation on the product may cause deterioration in characteristics and reliability.
*3: JEDEC level 5a
Note: Exceeding the absolute maximum ratings even momentarily may cause a drop in product quality. Always be sure to use the
product within the absolute maximum ratings.
