Optoisolators are widely used in many industries and applications, and offer protection from electric shock, noise, or voltage spikes. They are most commonly used in applications where one system needs to communicate electrically with another, while isolated from each other. Among the types of optoisolators available, a transistor, photovoltaic output, optoisolator can be used for switching and amplifying signals or applications, like a typical transistor.

H11D13SD Application Fields and Working Principle

H11D13SD optoisolators are primarily used in applications requiring high input to output isolation, as the isolation voltage between the two sides can reach between 2,500 and 5,000 volts. The H11D13SD device is a Transistor Output Photovoltaic Optoisolator, employing a monolithic optocoupler which combines both an LED light source and a silicon photodetector in a single package. This technology allows for very high isolation and voltage control.

The working principle of H11D13SD optoisolators is based on the photovoltaic effect, which is a phenomenon in which light generates an electric current in a material that is exposed to it. In the device, the LED light source ensures both high input-to-output isolation and an improved response time. When the LED is turned on, a detector converts the light into a voltage, which is then amplified by the transistor output amplifier to provide the desired voltage output.

The isolation voltage of H11D13SD optoisolators is determined by the value of the LED’s reverse operating voltage. The optoisolator provides a guaranteed minimum isolation voltage which is designated as the minimum isolation voltage (VIs), and is typically set at 5,000 volts.

H11D13SD optoisolators have a number of other desirable features, such as a small form factor, an operating temperature range from -40°C to +85°C, and a wide range of output currents. These optoisolators can also be used in a wide variety of applications, including audio visual equipment, waveform generators, communications equipment, robotics controllers, and industrial automation systems.
