Optoisolators are electrical components that provide a reliable electrical isolation between two circuits while allowing signals to pass between them. They are designed to ensure that the voltage from one circuit does not get transmitted into the other, preventing any potential short circuits or overloads from occurring. The PC81713NSZ1H optoisolator belongs to a class called transistor, photovoltaic output (TPO), and it has several uses in the power electronics industry. This article will look at the applications and working principles of this type of optoisolator.

The PC81713NSZ1H Optoisolator

The PC81713NSZ1H optoisolator is a component developed by Mitsubishi Electric Corporation™. It consists of a gallium arsenide infrared-emitting diode (IRED) and a phototransistor, joined together in a compact four-pin package. The photoelectric device is designed to ensure complete galvanic isolation between circuits, allowing signals to pass between them while blocking any power flow. The unit is also protected from dust, dirt, and other external factors due to its robust epoxy resin construction.

Applications

The PC81713NSZ1H optoisolator is designed for use in power converters, relays, light dimmers, and other circuits requiring light detection. It can be used in any application which requires the safe transmission of data from one circuit to another. The optoisolator also provides superior noise suppression and electrical insulation, making it an ideal choice for electrical insulation. It is also suitable for use in safety and medical equipment, due to its high level of isolation and electromagnetic noise protection.

Working Principle

The PC81713NSZ1H works on a simple principle. The IRED component emits a signal of infrared light, which is then received by the phototransistor. This causes the phototransistor to conduct, creating a circuit and allowing electric current to flow from the input to the output. In this way, the optoisolator creates electrical isolation between the two circuits, while transmitting data signals between them. The resulting circuit is protected from dust, dirt, and other external factors due to its robust epoxy resin construction.

Conclusion

The PC81713NSZ1H optoisolator is ideal for use in power electronics applications which require reliable electrical isolation between two circuits. It is designed to protect from dust, dirt, electromagnetic noise, and other external factors, making it an excellent choice for safety and medical equipment. Its simple working principles also make it easy to understand and use, and its robust construction ensures long-term reliability.
