Construction
How to Use
A voltage is provided to the two terminals of the emitter and collector to impart a reverse bias voltage to the collector junction, and the phototransistor is commonly employed in an open base condition (there are two external wires in many situations). A photocurrent (I) flows between the reversely biased base and the collector when light is incident on the surface of the base in this state, and the same is true for the transistor whose emitter is grounded. The photocurrent (Ic) flowing to the external terminal is amplified, and the current amplification rate of the current traveling through the transistor of the second stage is amplified. As a result, the first stage is the photocurrent flowing to the external wire. In the first and final stages, the product of the photocurrent flows between the base and the collector and the current amplification rate of the transistors.
