An optoisolator, also known as an optocoupler, photocoupler, or optical isolator, is a device that uses light waves to electrically connect or isolate two separate circuits. MOC3083S is one type of optocoupler which belongs to the Triac, SCR output family. This article is about MOC3083S application field and its working principle.

Application of MOC3083S

MOC3083S is mainly used for general lighting, street lighting, stage lighting, and other AC motor control equipment. It is suitable for controlling incandescent lamps, fluorescent lamps, and AC power devices in any complicated environment. Besides, the operating temperature range of MOC3083S is -40℃~+85℃. The wide operating temperature range helps it can be used in many places, like those especially cold or extremely hot places. Moreover, with its ceramic package, it is also a kind of durable optocouplers.

Working Principle of MOC3083S

MOC3083S is an integrated-optical device. In general, it consists of an infrared diode (LED) and a photocoupler surrounded by a light shield. When the LED is lit, photons sent by it will be used by the photocoupler to turn on components such as triac, SCR, and so on. MOC3083S could work under AC or DC control conditions, making sure stable operation. Moreover, it has an unidirectional conductive current-triggering gate, which avoids directly connecting input and output. This feature ensures that both input and output circuits are isolated from each other, thus perfect electrical insulation is achieved.

Conclusion

MOC3083S is a kind of optocoupler which belongs to the Triac and SCR output family. It has wide application field and benefits from its wide operating temperature range and its ceramic package. It works mainly by using light waves to connect or isolate two separate circuits. In addition, it has a unidirectional conductive current-triggering gate, which ensures perfect electrical insulation and stable operation.
