Optoisolators are electrical components used to isolate a circuit from a high voltage or hazardous environment. The H11C4W optoisolator series is a Triac, SCR Output type device, ideal for use in demanding applications such as industrial automation and control, communications, motor control and lighting.

A Triac, SCR Output, optoisolator is composed of a light-emitting diode (LED) coupled to a silicon photosensitive device such as a light activated or phototransistor. When an electric voltage is applied to the LED, it emits light that triggers a change in the resistance of the device, blocking or conducting current depending on its configuration.

The H11C4W series is based on the patented Triac, SCR Output structure, with an integrated phototransistor connected to a light-emitting diode. This gives the optoisolator a high level of noise isolation, which is essential in higher-voltage applications since it helps to prevent interference and enhances reliability. In addition, the H11C4W has two-way power commutation, meaning that it can work at zero crossing for input and output, enabling the power savings in motor control applications.

The H11C4W is also designed to withstand voltage transient spikes up to 8 kV and has a wide operating voltage range of up to 250 V. This makes it suitable for use in circuits that experience high voltage levels, such as in AC motor control applications. The H11C4W is also designed to be capable of operating in a wide temperature range, from -40°C to +105°C, making it suitable for use in harsh environments.

The H11C4W optoisolator series is available in a variety of packages and pin outs, making it easy to find the right device for the application. To provide the highest level of isolation, the H11C4W optoisolator series is manufactured on a special production line using a high-temperature encapsulation process.

In summary, the H11C4W optoisolator is a reliable, robust device even under high-voltage applications. Its integrated phototransistor and LED enable low power consumption, two-way power commutation and a wide operating temperature range. And, because it is available in a variety of packages and pinouts, it is easy to select the right device for the application.
