KODENSHI CORP. an industry leader in PHOTO-SENSOR WORLD,now offers "DAYLIGHT SENSOR (Ambient Light Photo Transistor) PT337P11 、PT337P11A and PT337P11FA". PT337P11, PT337P11A and PT337P11FA are the goods for replacement of CdS cell . These new products has turned to the same top-view package and has the same lead-pitch as CdS cell.These are the photo-transistor which built in the optical filter,and the spectral sensitivity is the similar to human's eye sensitivity characteristics. These has excellent output linearity and are making device suitable for ON/OFF switching functions for Lighting equipments、Clock、Display-backlighting control and other applications.
