Ambient Light Sensor

DESCRIPTION

TEPT4400 ambient light sensor is a silicon NPN epitaxial

planar phototransistor in a T-1 package. It is sensitive to

visible light much like the human eye and has peak

sensitivity at 570 nm.

FEATURES

• Package type: leaded

• Package form: T-1

• Dimensions (in mm): Ø 3

• High photo sensitivity

• Adapted to human eye responsivity

• Angle of half sensitivity:

ϕ = ± 30°

• Material categorization:

for definitions of compliance please see

APPLICATIONS

• Ambient light sensor for control of display backlight

dimming in LCD displays and keypad backlighting of

mobile devices and in industrial on / off-lighting operation

• Replacement of CdS photoresistors

Note

• Test condition see table “Basic Characteristics“

Note

• MOQ: minimum order quantity
