The 3N245 is a three-terminal optoisolator, consisting of an infrared LED (light-emitting diode) light source encased in an epoxy-encapsulated package. Its name is derived from the device’s ‘3N’ type (the object’s surface has a black finish) and its model number, which is ‘245’. The 3N245 optoisolator was designed to perform electrical isolation between its input and output circuits at up to 500Vrms, typically. Its peak output current is determined by the ambient temperature and the maximum temperature rise of the device, and can reach up to 10 milliamps.
The 3N245 optoisolator has a range of application fields. It is often used in motor control applications as a control system interface, due to its high electrical isolation levels. It is also employed in other types of control applications, such as in the automotive, industrial, telecoms, and domestic markets. Additionally, the device is also used in lighting control systems, medical equipment, information appliances, and various other equipment.
When it comes to its working principle, the 3N245 optoisolator works by relying on photoelectric amplification to transfer a signal from its input to its output. The device is comprised of an infrared LED encased in an epoxy-encapsulated package, which acts as the fed-in light source. This generates an infrared signal, which is then amplified using an additional photovoltaic amplifier to produce a stronger signal. Its output stage then takes this amplified signal and passes it through a transistor, transforming it into an electric signal, free of any interference or power surge. The electric signal is then output from the 3N245 optoisolator, complete with its high-level of electrical isolation.
In conclusion, the 3N245 optoisolator is a transistor-photovoltaic output device designed for applications requiring electrical isolation between input and output circuits. This optoisolator makes use of photoelectric amplification to transfer a signal from its input to its output stage, which then passes it through a transistor before outputting a signal with a high-level of electrical isolation. The device is incredibly versatile, with applications ranging from motor control to lighting control, and can perform up to 500Vrms of electrical isolation.
