H11D2300 Optoisolators are a type of optically-activated, solid-state electrical switching device. They are typically used to transfer an electrical signal from one area of a circuit to another, while isolating the two parts of the circuit from one another. This isolates the two sections of the circuit, providing electrical noise and surges protection, and can also provide an effective and reliable safety feature in many circuit designs.

H11D2300 Optoisolators use a combination of a light-emitting diode (LED) and a phototransistor to detect the electrical signal. The LED is activated by an external electrical signal, which in turn emits light that is detected by the phototransistor. The phototransistor then converts the light into an electrical signal, which can then be used to control other components in the circuit. As the LED and phototransistor are optically isolated from each other, there is no direct electrical connection between the two components, providing maximum levels of protection.

The H11D2300 Optoisolator is ideally suited to industrial control applications, thanks to its excellent noise isolation, as well as its ability to detect and respond to fluctuations in applied voltage quickly and accurately. The device typically comes in a 4-pin package, with the first two pins acting as the input pins, while the third and fourth pins act as the output pins. The applied voltage range for the H11D2300 is typically between 10 and 30 volts, although other voltage ranges are available depending on the particular application.

H11D2300 Optoisolators are designed to operate over a wide range of temperatures and have a good noise immunity, enabling them to operate reliably in harsh industrial environments. The device also offers an excellent thermal resistance, so that it can be effectively used when the surrounding environment is subject to drastic temperature changes. One of the key advantages of H11D2300 devices is their low current consumption, typically around 5mA, meaning that their operating power is minimal.

The working principle of the H11D2300 Optoisolator is based on the light-emitting diode emitting light when an electrical signal is applied to its anode, and the phototransistor detecting the light and generating a corresponding electrical signal. When the LED is lit, the current flowing through the phototransistor increases, indicating that the electrical signal has been detected. When the LED is not lit, the current flowing through the phototransistor decreases, thus stopping the electrical signal. This basic principle is utilised by all optoisolator devices in applications such as logic switching, temperature and voltage sensing, and level detection.

The H11D2300 Optoisolator is suitable for a wide range of industrial control applications, such as power management, current detection, level detection, and switching systems. Due to its low current consumption, it is also a popular choice for applications requiring low-power solutions. Its excellent noise isolation allows it to be used in applications where the circuit must be kept isolated from external electrical noise. Furthermore, thanks to its wide operating temperature range, it can be reliably used even in harsh industrial environments.
