Optical sensors, such as phototransistors, are used for detecting light, such as the SFH 320 FA-3-Z application field and working principle. Phototransistors are a type of light-sensitive transistor that respond to light-sensitive optoelectronic switching applications. These transistors can be placed in a variety of configurations in order to sense light in various ways.

When light strikes the surface of a phototransistor, its collector-base junction is reversed biased. As a result, current flows from the collector to the base and this causes a current flow from the emitter of the transistor to the collector. Depending on the type of phototransistor, this current flow can range from microamperes to milliamperes and will depend on the amount of light incident on the phototransistor. The output of the phototransistor can be used to drive a LED, connect to an amplifier, or be used as a direct light output.

The SFH 320 FA-3-Z is an optically-triggered NPN phototransistor that forms a stable, electrical connection when exposed to light. This phototransistor has a maximum operating voltage range of 10 to 16 volts and a maximum operating temperature range of -40°C to 105°C. In addition, the phototransistor is capable of operating within a frequency range of 1 MHz and a typical rise time of 8 ns.
