EL357N(C)(TA)-VG Working Principle

The EL357N(C)(TA)-VG optoisolator consists of a light-emitting diode, an integrated NPN transistor, and an integrated resistive collector load. The device operates in a voltage-mode configuration, with an input voltage of between 4.5V and 12V and a collector current of up to 20 mA maximum. The integrated NPN transistor is used to switch the output voltage, which is represented by the collector current.

When operating, the LED inside the device produces monochromatic light when a forward voltage is applied. This light generated from the LED is then detected by the optoisolator, which then results in a voltage drop of the collector current. By adjusting the input voltage, the output current of the optoisolator can be increased or decreased. As the voltage is increased, the output current also increases, which is known as Alpha value. Conversely, the voltage can be decreased, resulting in a decrease in output current.

The EL357N(C)(TA)-VG optoisolator is also an environmentally friendly device that is suitable for use in voltage mode applications that require up to IA maximum output current. The device can also provide fast switching speeds of up to 10 kHz, making it ideal for applications where switching speed is important such as those in motor control and lighting control.

Conclusion

The EL357N(C)(TA)-VG is an optoisolator providing high-speed isolation and signal conversion between two circuits. Its fast switching speeds of up to 10 kHz make it suitable for applications such as motor control, overvoltage protection, battery-powered systems and lighting control. Additionally, its welded construction ensures reliable and durable performance.
