MPPC is a type of device called SiPM (silicon photomultipliers). It is a new type of photon counting device that consists of
multiple Geiger mode APD (avalanche photodiode) pixels. It is an opto-semiconductor with outstanding photon counting
capability and low operating voltage and is immune to the effects of magnetic fi elds.
The S14420 series is an MPPC for the visible to near infrared region. It provides higher photon detection effi ciency than the
previous product (S13360 series) in the visible to near infrared region.
High photon detection efficiency: 40% (λ=600 nm, Vop=VBR + 5)
Low crosstalk, low afterpulses
Low voltage (VBR=42 V typ.) operation
High gain: 10
