TEPT5600 – Small sensor, big possibilities

The TEPT5600 phototransistor is a versatile light sensor designed for precise detection of light intensity across various wavelength ranges. Its compact package and high sensitivity make it widely applicable in automated, monitoring, and control systems that respond to changing ambient lighting conditions.

Key Features:

• Package Type: T-1¾ (5 mm diameter)
• Half Sensitivity Angle: ±20°
• Wavelength Sensitivity Range: 440 nm to 800 nm
• Maximum Collector-Emitter Voltage: 6 V
• Maximum Collector Current: 20 mA
• Operating Temperature Range: -40°C to +85°C

Applications:

The TEPT5600 is widely used in various technological fields, particularly in systems requiring light intensity detection:

• Ambient Light Intensity Measurement: Used in devices that need to react to changing lighting conditions, such as automatic brightness adjustment systems for LCD screens that adapt display brightness to surrounding light levels.
• Automatic Display Brightness Control: Commonly integrated into phones, TVs, computers, and other devices that automatically adjust screen brightness based on ambient light.
• Street and Building Lighting Systems: Plays a role in smart lighting systems where sensors respond to external lighting changes (e.g., day/night detection) to automatically turn lights on or off.
• Aperture Detection in Optical Devices: Used in cameras, binoculars, and optical instruments to detect light passing through lenses and adjust aperture settings accordingly.
• Industrial Sensor Applications: Serves as a key component in industrial devices such as presence sensors, detecting changes in light intensity under specific conditions.
