Optical sensors are devices that capture and measure light photons, and phototransistors are a type of semiconductor device used within optical sensors to detect the presence of light. A common example of a phototransistor is the SFH 300 FA-3/4 (SFH for Silicon, Germanium and Hyperfrquency). It has a wide range of applications, including industrial and medical uses. This article will explain the working principle of this phototransistor and the fields of its application.
The SFH 300 FA-3/4 is an NPN-style phototransistor built with a single photodiode and two PN junctions that create a bipolar transistor. The device has a collector-emitter voltage of 20V, and its maximum allowable reverse voltage is lower than other phototransistors. The SFH 300 FA-3/4 is also able to handle higher collector currents and has a response time between 1 microsecond and 10 milliseconds.
The principle of the SFH 300 FA-3/4 phototransistor is based on the effect of a reverse-biased photodiode in the presence of light. When photons from a light source hit the photodiode, they are absorbed by the junction and create electron-hole pairs. These electron-hole pairs act as minority charge carriers in the junction and strongly affect the current through the device. The generated current can then be measured by connecting a load to the device.
The SFH 300 FA-3/4 is mainly used in industrial and medical sensor applications, including optical communication systems, flap detection, pyrometry, bar code and document retrieval, UV black light, and medical imaging. In optical communication systems, this phototransistor is used to detect optical signals transmitting between two points, while in flap detection it is used to detect the movement of a flap. The phototransistor is also used in pyrometry, where it is used to measure temperature and any other parameters associated with the temperature. In bar code and document retrieval, the SFH 300 FA-3/4 is used to detect the presence of codes and documents, while in UV black light it is used to detect ultraviolet radiation. Finally, the device is used for medical imaging, where it is used to detect radiation emitted by human tissue for diagnostic purposes.
The SFH 300 FA-3/4 is a versatile phototransistor that has a wide range of applications in industrial, medical, and technological fields. It is a powerful device that can be used to detect and measure light photons, and its response time and maximum allowable reverse voltage make it a great choice for a variety of applications. With its reliable performance and wide range of applications, the SFH 300 FA-3/4 is an ideal device for the measurement of light radiation in a variety of settings.
