Dual-element photodiode using newly developed small, thin package
S9345 is a dual-element Si PIN photodiode employing a newly developed small, thin plastic package. The cubic volume reduced to one-
fifth that of similar type photodiodes using conventional package. In order to extend the detection area when used as a reflection-mode
optical switch, the entire photodiode active area of 1.5 mm wide and 5.6 mm long is asymmetrically segmented into 2 longitudinal sections
of 1.5 mm and 4.1 mm.
