Low breakdown voltage type MPPC for scintillation detector


The S14160 series achieve higher PDE (photon detection efficiency) and lower operation voltage than other MPPC to adapt for PET and radiation monitor application. They achieve small dead space in a photosensitive area with HWB (hole wire bonding) technology (Patent pending). And the gap from the photosensitive area edge to the package edge is only 0.2 mm. This package realizes the four-side buttable arrangement.

-Higher PDE: 50% at λp, Vop=VBR + 2.7 V
-Lower voltage operation: VBR=38 V typ.
-Small dead space in photosensitive area
-low afterpulses and crosstalk
-High gain: 106 order
-Excellent time resolution
-Immune to effects of magnetic fields
