The S14160/S14161 series achieve higher PDE (photon detection eciency) 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.
Features
Higher PDE (50% at λp, Vop=VBR + 2.7 V)
Lower voltage (VBR=38 V typ.) operation
Small dead space in photosensitive area
Low afterpulses and crosstalk
High gain: 10

*1: No dew condensation
When there is a temperature dierence between a product and the surrounding area in high humidity environment, dew condensation
may occur on the product surface. Dew condensation may cause deterioration in characteristics and reliability.
