Additional Details

The TCST1000 phototransistor responds to incoming light by generating a collector current proportional to the light intensity. The miniature SMD package allows for easy integration into compact devices. Its wide angle of half sensitivity makes it suitable for applications where precise alignment is not critical.

Refer to the Vishay datasheet for detailed specifications, including operating conditions, electrical characteristics, and typical application circuits. An external resistor is typically required to limit the collector current and set the sensitivity of the phototransistor. Proper shielding may be necessary to minimize the effects of ambient light.
