OED-ST-23-TR

Optical sensors are components which convert light energy into an electric current. Phototransistors are one of the most commonly used optical sensors widely applied in industrial automation, sensing, and other fields. The OED-ST-23-TR phototransistor is a medium power, single channel NPN phototransistor with a low emitter saturation voltage, offering superior sensitivity over a wide range of conditions.The OED-ST-23-TR has a built-in emitter-coupled logic (ECL) circuit which allows it to operate on any voltage from 1.5V to 12V. This makes it suitable for high-speed operation and operation under a wide range of environmental conditions. The OED-ST-23-TR is extremely sensitive to light and can detect even very dim light levels. It can be used in applications where very low levels of light must be detected, such as night vision, security applications, or in applications where a very small amount of ambient light must be detected. The OED-ST-23-TR phototransistor consists of a semiconductor PN junction, formed by two layers (emitter and collector) of semiconductor material, making it a three-terminal device. The emitter and collector form the two electrodes of the device and the base is the control terminal connected to the external circuit. The PN junction creates an electric field across it which affects the flow of current through the device. When light strikes the PN junction, the electric field is changed and the current flowing through the device is also changed. This is the basic principle of operation of the OED-ST-23-TR phototransistor.The OED-ST-23-TR has three pins, E, C, and B (Emitter, Collector, and Base). It is typically used in the common emitter configuration in which the E and C pins are connected to the emitter lead and collector lead of the external circuit, respectively. The B pin is connected to the base lead of the external circuit. When light is incident on the semiconductor junction, the current flow through the device increases, resulting in the output voltage also increasing. The output of the OED-ST-23-TR phototransistor is a voltage signal which can be monitored by the external circuit. The OED-ST-23-TR phototransistor is used in many industrial applications such as sensing, home automation, medical devices, and analyzers. It can also be used for light detection and dimming control in home and commercial lighting systems. Its high sensitivity and low voltage operation make it an ideal choice for high-speed, low-power applications.In summary, the OED-ST-23-TR phototransistor is an extremely sensitive optical sensor with a low saturation voltage and low-emission current, suitable for high-speed operation and operation under a wide range of environmental conditions. Its inbuilt ECL circuit allows it to operate on any voltage from 1.5V to 12V, making it highly suitable for any application where low light levels must be detected. Its three terminals, E, C, and B, provide the control and output functionality which can be easily monitored by the external circuit.
