TEPT4400 Description

Short technical summary and product information.

The Vishay Dale TEPT4400 is an ambient light sensor utilizing a silicon NPN epitaxial planar phototransistor housed in a T-1 package. This component is specifically designed to be sensitive to visible light, closely matching the spectral response of the human eye, with a peak sensitivity at 570 nm.

 

Key features include high photo sensitivity and an angle of half sensitivity of ± 30°. The TEPT4400 operates within a temperature range of -40 °C to +85 °C and has a collector current rating of 20 mA. Its power dissipation is rated at 100 mW at or below 55 °C.

 

This phototransistor is suitable for applications such as controlling display backlight dimming in LCD displays and keypad backlighting in mobile devices. It can also be used in industrial on/off lighting operations and serves as a replacement for CdS photoresistors.
