TEPT4400 - Vishay Siliconix

TEPT4400 Ambient Light Sensor

TEPT4400, photo transistor for ambient light sensor application, plays a key role in power savings strategies by controlling LCD display intensity and keypad backlighting of mobile devices and in industrial on/offlighting operation. It is sensitive to visible light much like the human eye and has peak sensitivity at 570 nm. TEPT4400 is packaged in a T 1" pac.
