Optoisolators are components capable of electrical isolation of two circuits, useful in cases when the output of one circuit must be connected to an input of another. An example of such an application is controlling a load from a logic circuit. The H11C3 is a 6-pin general-purpose optoisolator featuring a triac, SCR output.

The H11C3 Working Principle

The H11C3 optoisolator contains a LED which is optically coupled to a triac or SCR. The LED is used to provide an optical connection between the input and output circuits. When the input signal is applied to the LED’s anode and the LED’s cathode is held at ground, current will flow through the LED. This, in turn, will illuminate a photodiode in the output circuit and cause the triac or SCR to be activated.

The H11C3 has a wide input voltage range of 5V to 20V and is capable of providing up to 1000V of isolation between input and output. It has two different output configurations, a triac or an SCR. In the triac configuration, the output is a triac which is capable of driving up to 400VAC with a maximum current rating of 10A. The SCR configuration provides an SCR output for switching DC loads up to 400V with a maximum current rating of 2A.

H11C3 Application Fields

The H11C3 optoisolator is useful in a variety of applications. It can be used to isolate a logic circuit from a power circuit, or to provide isolation between two different sections of a circuit. Some of the applications where the H11C3 can be used include lighting control, temperature control, process control, motor control, power supply protection, and more.

In lighting control applications, the H11C3 can be used to control multiple lights from a single input signal. In temperature control applications, the H11C3 can be used to switch a heating or cooling device on and off depending on the temperature. In motor control, the H11C3 can be used to control the speed of a motor by using a variable voltage input signal.

In addition to these applications, the H11C3 optoisolator can also be used in a variety of other applications where electrical isolation is required. This includes power supply protection, noise immunity, and other applications where reliable electrical isolation is needed.

Conclusion

The H11C3 optoisolator is a versatile and reliable component that can be used in a variety of applications where electrical isolation is required. It is capable of providing up to 1000V of isolation between input and output, and has two different output configurations, a triac or an SCR. The H11C3 can be used in lighting control, temperature control, process control, motor control, power supply protection, and many other applications.
