IL4117-X001

The IL4117-X001 is an optoisolator from Harris’ Semiconductor\'s IL4000 series. It is a Triac Output optoisolator, meaning it is ideal for switching higher DC and AC loads. This device is usually used when there are voltage level differences in the input and output, or for optical coupling between two circuits.

The working principle of this device is based on the well-known concept of a triac optoisolator. When the LED within the device is on, a current flows through the triac and the load can be switched on or off. The current is conducted through the optical isolator, which is a photodetector and a transistor that convert the electrical input signal to light. The light is seen by the phototransistor, and a current is returned through the material. This current will switch the load that is connected to the triac.

The main application field for the IL4117-X001 optoisolator is switching higher DC and AC loads like fluorescent ballasts and impeding voltage level differences between two circuits. It is also used in communications systems to insulate the transmitting and receiving side of the circuit. It is ideal for using in motor control applications because of its high coupling capacity. In addition, it can be used as a gate interface to dimmer systems, switching power transformers, over-current protections, solar inverters, and many other applications.

This optoisolator has a very low operating current of 18mA and a very low power consumption of 2.7W. Its peak blocking voltage is 1000Vrms and its quiescent current is 1mA. In addition, it has an extremely low turn-on and off-delay time, and a good noise immunity.

Harris Semiconductor’s IL4117-X001 optoisolator is a popular choice for many applications. It provides good isolation and is very reliable. Its low power consumption and high coupling capacity make it suitable for switching higher DC and AC loads. It is also widely used in communication systems, motor control applications, and more.
