Optoisolators are electrical components that are used to isolate signals from a power source. H11C33SD Optoisolators are a type of optoisolator specifically designed to provide electrical isolation between two circuits using an optoelectronic device to convert the electrical signals from the input side to light signals, driving the output side device. It is a triac, SCR output optoisolator.

Overview of H11C33SD

The H11C33SD optoisolator is an isolated triac output type device designed for use with AC or DC signals. It has a built-in single-channel Hi SMT (Surface Mount) Triac, allowing for easy installation while providing reliable performance. The device can withstand up to 8 amps of current and voltage up to 600V. Additionally, it provides excellent isolation from the input side, with a CMRR at least 2000V RMS and a dielectric strength of 3250VAC for one minute. The device is also RoHS compliant.

Application Field and Working Principle

The H11C33SD optoisolator is most commonly used in industrial applications such as motor control, temperature control, lighting, and other control systems. It is also suitable for use in both AC and DC applications. The device works by transferring electrical signals from the input side to light signals that are then received by the output side device, thus providing electrical and optical isolation.

The H11C33SD works by converting the input voltage to light signals which are then received and amplified by the output side device. The output side device then produces a voltage which is applied to the triac, fires it, and the output is then sent back to the input side. The process is then repeated as long as the input signal remains. The device can control a wide range of power signals, from 0V to 600V per channel. In addition, it has a low trigger current, making it ideal for low power applications.

Advantages of H11C33SD

The H11C33SD optoisolator offers several advantages over competing products. Firstly, the device is extremely reliable, with a data retention period of up to 24 hours. Secondly, it is UL recognized, ensuring that the device meets safety standards. Thirdly, it offers excellent isolation with a CMRR of up to 2000V RMS and dielectric strength of up to 3250VAC for one minute. Lastly, it is very small and lightweight, making it ideal for applications where space is limited.

The H11C33SD optoisolator is a highly reliable and versatile component that offers excellent electrical and optical isolation between two circuits. Its small size and low trigger current make it ideal for applications where space is limited and low power signals must be controlled. In addition, its UL recognition ensures that the device meets safety standards. As such, it is perfect for a number of industrial applications, such as motor control, temperature control, lighting, and other control systems.
