Optoisolators, or optical couplers, provide electrical isolation between digital and analog circuits while allowing them to communicate with each other. The H11AA814300W is a transistor, photovoltaic output optoisolator from the Optokon family. It consists of a light emitting diode (LED) coupled with a photovoltaic detector through an optically opaque shield.

The H11AA814300W contains a 14-pin dual-in-line package (DIP), two leads of which control the LED current and the four other leads control the photodetector current and the output voltage. The electronic input circuit is typically applied with inputs of 0-10V, 0-5V or 0-2.5V. The output circuit is a single-pole, single-throw (SPST) type with an open-collector NPN transistor.

The H11AA814300W provides electrical isolation up to 2500 volts peak and has a typical response time of 3.5 μs. The operational temperature range of the device is from –25 to 85°C. The optoisolator also has a storage temperature range of –40 to 105°C.

The optical coupling of the H11AA814300W offers a first line of defense against noise interference and prevents accidental conduction of high current and voltages. This optoisolator provides reliable electrical isolation, protects expensive equipment from damage and allows for galvanic separation in control circuits. It is often used in applications where there are electrically noisy environments or high-voltage circuit configurations.

The H11AA814300W optoisolator works by using current transferred through the LED to activate a photovoltaic detector. When the LED is energized, it sends a current across the LED. This current interacts with the photodetector, which faces the LED across the optically opaque shield. When the photodetector receives the light, it produces an electrical current that operates the output transistor switch.

The H11AA814300W optoisolator is capable of providing isolation, noise rejection, and support for a variety of applications. It is often utilized in applications such as industrial controllers, temperature control systems, HVAC systems, lighting controls, electronic instruments, automotive systems, and medical equipment.
