Optoisolators - Transistor, Photovoltaic Output,may be compared to an optical switch, using a phototransistor as the active component for switching output - with the option of photovoltaic operation. The H11A817C3SD optoisolator is specifically designed for reliable operation in optically isolated applications from both logic and power circuits.

The working principle of this optoisolator is based on an LED driving a phototransistor through a transparent shield. The basic operational concept of this optoisolator is the transfer of energy through an optical link. When a control signal, such as voltage or current, is applied to the LED, it emits light in the visible wavelength which is then absorbed by the phototransistor. The phototransistor is then activated, creating a current that is outputted from the other side of the optoisolator.

The H11A817C3SD offers photovoltaic operation, which is the generation of an electrical output in response to the optical energy received. This offers an alternative to logic operation, which is the control of digital outputs. Photovoltaic operation requires no external power source, while logic operation requires an external power source, such as a battery, in order to power the LED in the optoisolator. In this way, the H11A817C3SDcan serve as a standalone device, providing both optical isolation and digital switching capability.

The H11A817C3SD is designed specifically for industrial and automotive applications where its reliability and longevity are of utmost importance. It’s built with a microcontroller, an 8-bitprocessor and an LED wit h a peak current rating of 30mA. The optoisolator also features a light-sensitive package, with a maximum operating temperature of -55°C to120°C for reliable performance in extreme temperatures. The package provides efficient thermal conductivity, allowing the optoisolator to dissipate heat while still providing optical isolation.

The H11A817C3SD optoisolator offers a wide range of features that make it an ideal choice for industrial applications. Its wide operating temperature range makes it suitable for use in harsh industrial environments, while its compact size and low power consumption make it ideal for automotive applications. It also offers high accuracy performance and fast switching times, making it an ideal choice for logic control applications. With its small package size, it can be easily integrated into existing circuits and systems. Last but not least, its optoisolation reduces the risk of electrical noise and interference, making it an excellent choice for sensitive electronic circuitry.

In summary, the H11A817C3SD optoisolator is an excellent choice for a wide range of industrial and automotive applications. It offers both optical isolation and digital switching capability, in a small, efficient package. With a wide operating temperature range, high accuracy performance, and fast switching times, the H11A817C3SD is an invaluable addition to any circuit.
