Optoisolators, sometimes referred to as opto-couplers or opto-isolators, offer very effective means of isolating an electronic control system from an external source of electrical noise. They are widely used in industrial systems to protect sensitive electronic components and prevent data corruption. The H11AG2300 is an optoisolator specifically designed to provide galvanic isolation between high voltage power supplies and control circuitry. In this article, we will take a look at the application field and working principle of the H11AG2300.

Application Field

The H11AG2300 is an optoisolator used primarily in industrial applications that require high voltage isolation. It is capable of providing isolation from 24 to 140 Volts, making it suitable for use in medium voltage control circuits. It is also resistant to short-term voltage transients up to 300 Volts. The device is designed with an smd package, making it easy to incorporate in to control circuit layouts, as well as making it suited for use in various environments that require increasing levels of vibration and shock resistance.

The H11AG2300 is capable of providing up to 1A of output current, which makes it suitable for controlling motors or other loads. Its small package size also makes it suitable for use in tight spaces. Furthermore, the device is able to detect input voltages up to 140VACRMS with an isolation voltage of 5,300V RMS, making it suitable for use in high-voltage control applications.

Working Principle

At the heart of the H11AG2300 is a light-activated switch, called a photo-coupler, comprised of an infrared LED and a phototransistor. The LED is used to emit a stream of infrared radiation which is then picked up by the phototransistor. The phototransistor changes its resistance based on the amount of light it is exposed to, which is then used to control current flow in the circuit.

The H11AG2300 consists of four main components - an optically isolated input, an integrated magnetic driver, an output transistor, and a phototransistor. The input is isolated from the rest of the circuit by the built-in magnetic driver. When an input signal is applied, the magnetic driver is activated and the phototransistor changes its resistance according to the amount of light it is exposed to. This change in resistance is then detected by the output transistor, which then controls the current flow in the circuit.

The H11AG2300 is a versatile optoisolator that can be used in a wide range of applications. It is capable of providing up to 1A of output current and is resistant to short-term voltage transients. Furthermore, its small size and smd package make it easy to incorporate into circuit layouts and suitable for use in tight spaces. The device is also able to detect input voltages up to 140VACRMS with an isolation voltage of 5,300V RMS, making it suitable for use in high-voltage control applications.
