KODENSHI CORP.

   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．
