Discrete LED indication is one of the most common types of light-emitting diode (LED) displays used to have lights light up when triggered by electricity. One such type of discrete LED indication is the C566C-BFE-CT0U0342.

This discrete LED indication is an optocoupler series that consists of a phototransistor and infrared emitting diode (IRED) operating as a switch. It is a small electrical device that works with an input current to control the output current through an LED. The LED stays off when the input current is low and turns on when the input current is increased. This type of LED indication is used in many applications from lighting indicators on circuit boards to medical equipment.

The C566C-BFE-CT0U0342 is a four-pin optocoupler that requires a supply voltage of 5 volts DC and a maximum forward current of 5mA. Its configuration also includes an IRED connected in series to the phototransistor as well as a reverse voltage protection diode. This LED indication utilizes a GaAlP (gallium aluminum phosphide) thin-film chip for the IRED and an epoxy lens for the phototransistor. This special configuration is designed to provide excellent speed, high collector-emitter voltage, and extremely low output current leakage.

In terms of its application field, the C566C-BFE-CT0U0342 is mainly used in applications related to lighting control and signal isolation, such as lamps, strobe lights, and alarms. For example, when current flows through the IRED, its output primary current activates the phototransistor, which then provides the required current to the LED. This type of LED indication can also be used in motor vehicles as LED indicators for lighting and steering. Additionally, the device can be used to provide visibility in outdoor signs, indicating traffic directions.

Overall, the C566C-BFE-CT0U0342 is an ideal discrete LED indication solution for numerous types of applications associated with lighting control and signal isolation. Its substrate-comedium structure and infrared-emitting diode combination make it an ideal choice for applications requiring a compact, reliable and robust indication system.
