Opto-isolators - Transistor, Photovoltaic Output

Opto-isolators, also known as optocouplers, are electronic components that transfer energy and signals between two isolated circuits. Examples of isolators include the LTV-0701, a photovoltaic output opto-isolator with a voltage input. This isolator provides superior isolation protection and performance, eliminating electrical noise and possible arcing, therefore making it suitable for applications that require higher voltages.

LTV-0701 Application Field

Opto-isolators such as the LTV-0701 are commonly used in applications with a wide range of input and output characteristics, such as temperature, pressure, and flow sensitive applications. The opto-isolator offers protection in instances where data communication, industrial, military, medical, and other sensitive electrical equipment is exposed to electrical shock, electrical noise, and power-line transients. Other application fields for the LTV-0701 are in telecommunications, automotive, industrial, and consumer electronic manufacturing. This opto-isolator can also be used in the communication of signals or data between two devices whose output characteristics are isolated from each other, such as between microcontroller boards and relay control devices, or to provide isolation between a signal and a power source.

LTV-0701 Working Principle

The LTV-0701 opto-isolator contains a light-emitting diode (LED) and a phototransistor, each with integral optical windows. The LED emits an infrared light, which is focused through the phototransistor’s optical window. The infrared light is then converted into a current, and this electrical current is amplified by the opto-isolator\'s amplifier stage. This signal is then sent to the base of the phototransistor, where it is amplified and sent to the output of the opto-isolator. The LED will only draw current from the external power source when it is illuminated, making it an economical and efficient device, consuming less power. The LTV-0701 opto-isolator is capable of providing input-to-output isolation up to 5000 volts (V). It also has very low power consumption and a high response time. This ensures that the opto-isolator is able to provide a reliable solution for applications requiring isolation at the highest voltages. The LTV-0701 opto-isolator is lightweight and compact, making it an ideal choice for applications that require a small form factor. Its wide operating temperature range of -55°C to 125°C ensures that it is suitable for use in most environments.

Conclusion

The LTV-0701 opto-isolator is a reliable and efficient solution for applications that require electrical isolation at high voltage levels. It offers protection from electrical noise and power-line transients, and is suitable for a wide range of input and output characteristics. Furthermore, its low power consumption and small size makes it ideal for applications that require a small form factor.
