Optoisolators are light-electricity conversion devices that are often used in modern electronic circuits. One of the most commonly used optoisolators is the TIL113M. This article will discuss the application field and working principle of the TIL113M, a photovoltaic output transistor optoisolator.

Application

The TIL113M optoisolator is a small, compact device that is used to provide electrical isolation between two circuits. It is a highly reliable device due to its low power consumption and its ability to provide up to 3000V of electrical isolation. It has many practical applications including:

• Isolating power rails in industrial electronics
• Operating logic circuits or TV receivers in high-voltage environments
• Electronic switching and feedback systems
• Protecting microcontroller input pins from overvoltage
• Instrumentation
• Motor control systems

Working Principle

The TIL113M optoisolator consists of two parts, an LED and a phototransistor. The LED is the light emitting diode that emits light when a voltage is supplied to it. The phototransistor is the photo-sensitive device that detects the light emitted by the LED and converts it into an electrical signal. The output signal of the phototransistor is then used to control other electronic devices.

The LED and phototransistor of the TIL113M are connected by a transparent plastic case. The plastic case is designed to allow light from the LED to pass through to the phototransistor while also blocking stray radiation from other sources.

When a voltage is applied to the LED, it emits light which is then detected by the phototransistor. The phototransistor then generates a current which is then used to control other electronic devices. The current generated by the phototransistor is proportional to the intensity of the light emitted by the LED.

The TIL113M optoisolator is designed to be highly efficient and reliable. The device has a low power consumption and is able to provide up to 3000V of electrical isolation. The device is also able to provide a high switching speed, allowing it to be used in fast switching applications.

Conclusion

The TIL113M is a reliable optoisolator used in many practical applications. The device is able to provide electrical isolation while also providing a high switching speed. Additionally, the device offers a low power consumption and a high voltage isolation up to 3000V. The device is highly reliable and efficient and is used in many electronic circuits.
