Description
The ALS-PT19-315C/L177/TR8 is consisting of phototransistor in miniature SMD. EVERLIGHT
ALS series product are a good effective solution to the power saving of display backlighting of
mobile appliances, such as the mobile phones, NB and PDAs. Due to the high rejection ratio of
infrared radiation, the spectral response of the ambient light sensor is close to that of human
eyes.
