Optoisolators - Transistor, Photovoltaic Output

Optoisolators are types of isolators commonly used in electronic circuits which separate high-voltage current from low-voltage signals. The H11A817W is an optoisolator of the Transistor form and Photovoltaic Output. This type of optoisolator utilizes a photovoltaic (PV) output and a transistor driver to separate high-voltage circuits from low-voltage circuits. When a digital input voltage signal is applied to the input side, the optoisolator produces a digital output voltage signal on the output side.

The H11A817W optoisolator is typically used in applications that require fast, low-cost isolation of a low-voltage signal from the electrical noise generated by a high-voltage circuit. Examples of such applications include high-power motor controllers, power supply systems, switching power supply systems, data acquisition systems, motor speed compensators, and closed-loop temperature controllers. The H11A817W is also often used in industrial automation and embedded applications such as factory controllers, motor controllers, and I/O systems.

The H11A817W optoisolator works by transferring electrical energy from one location to another without a physical connection between the two sides. It achieves this by pairing a light emitting diode (LED) and a phototransistor (PT) in its internal structure. When a voltage is applied to the PV input side of the optoisolator, the LED illuminates. This causes the phototransistor to switch on, thereby allowing current to flow in the output side. The output side then produces a voltage and current signal that is proportional to the voltage of the input signal.

The H11A817W optoisolator features a wide range of operating conditions with a low power consumption requirement. Its supply voltage ranges from 5V to 25V,while its supply current requirements range from 0 to 1.2mA. It can also withstand up to 5000V rms of surge voltage. Furthermore, the optoisolator has a built-in voltage output buffer and temperature range of -40 to 85°C – permitting it for use in extreme temperatures and harsh environment. It also exhibits high data rate transfer efficiency.

In conclusion, the H11A817W optoisolator is an advantageous type of isolator that enables efficient communication between circuits of varying voltages. Its fast response, low power consumption and wide operating conditions allow it to be applicable in a wide variety of industrial and embedded electronics applications. Its built-in voltage output buffer, high data rate transfer efficiency and temperature range allows it to operate in extreme environments, making it an ideal for many applications.
