Optical Sensors - Phototransistors are commonly used in a wide range of applications because they can detect and convert light signals into electrical signals. The QSB320FTR is a popular type of Photo Transistor which is used in many modern industrial and commercial electronic devices.

The QSB320FTR Photo Transistor is built with an integral light source and detector which makes it an ideal choice for applications that require fast response time and the ability to respond to a range of light levels. The device uses a photodetector to absorb light from its surroundings, then produce a photo-induced current that can be used to control various external electrical systems. It is also designed with a wide supply voltage range and has low noise characteristics.

The QSB320FTR Photo Transistor is mostly used in two main applications. Firstly, it is often used to trigger a switch so that an electrical circuit is activated when exposed to light. This type of application is often used in applications such as sensors that detect and measure light, or for controlling automated lighting in a home or industrial environment.

Secondly, it is also often used as part of an optoelectronic circuit. This involves using the phototransistor to detect light from a light source, and then producing an electrical signal in response. These types of applications are commonly used in camera systems, where the phototransistor is used as part of the autofocus system.

The working principle of the QSB320FTR Photo Transistor is relatively simple. When exposed to light, the photodetector within the device will absorb photons. This absorption causes a flow of current to be created, which is then converted into a proportional electrical signal. This signal is then used to control the external electrical system or device, as required.

The QSB320FTR Photo Transistor is a reliable, high-performance device which is used in many modern electronics applications. Its integral light source and detector, as well as its wide supply voltage range and low noise characteristics, make it an ideal choice for many complex industrial and commercial electronic devices.
