Optoisolators are an essential component in many electronic circuits, providing electrical isolation between two circuits in order to ensure the safety of system components. The MOC207M_F132 optoisolator is a photovoltaic output transistor optoisolator designed for low power signal isolation applications. This device is optically coupled with a high input impedance, low current output transistor, providing electrical isolation and wide dynamic range while preserving a low power consumption.

Applications

The MOC207M_F132 is especially useful for applications subjected to transient voltage spikes, due to its high insulation voltage rating of 5,300VAC. It is commonly used in the telecommunications, medical, automotive, consumer, industrial, and instrumentation electronics fields. It is used in an array of applications, including surge protection, safety barriers, data signal transmission, output voltage isolation, and AC and DC optically isolated switches.

Working Principle

The primary function of the MOC207M_F132 optoisolator is to electronically isolate two circuits by providing a photovoltaic or a phototransistor output. It incorporates an infrared light emitting diode (LED) and a Light Dependent Resistor (LDR). When current passes through the LED, light is emitted, and is detected by the LDR on the receiving side. This changes the resistance on the receiving side, allowing current to pass and switching the receiving transistor on or off achieving electrical isolation. This isolator works with input voltages as low as 1.4V, giving a wide dynamic range in process.

The optoisolator’s output is highly immune to environmental parameters, including temperature, humidity, vibration, and electromagnetic radiation, making it an ideal choice for many applications. Also, as it is non-contact, it does not require physical connection, reducing the risk of short-circuits and humidity-related damage. The MOC207M_F132 resistor has a schottky diode at the input end in order to prevent reverse operation of the circuit. This increases the overall stability of the optoisolator, providing reliable and secure performance.

Conclusion

The MOC207M_F132 optoisolator provides isolated signal transmission and electrical isolation between two circuits, while providing reliable performance and low power consumption. Its low input voltage, wide dynamic range, and the ability to withstand environmental parameters make the MOC207M_F132 an ideal solution for many applications where electrical isolation is needed.
