Optoisolators – Transistor, Photovoltaic Output

Optoisolators, also known as optocouplers, opto-isolators, or optoelectronic couplers, are devices that allow communication between two otherwise electromagnetically isolated circuits. They are widely used in industrial and military applications, as well as consumer electronics applications.

FOD817BSD Application Field and Working Principle

The FOD817BSD optoisolator is an isolated 10-pin DIP package. It has a low-level digital output, typically 1/2 watt, transistor output, and photovoltaic output. FOD817BSD is used in various applications including industrial machine controls, power supply control, HVAC systems, and in motion control systems.

The working principle of the FOD817BSD is simple: when the LED internal to the package is energized, it emits light on the photovoltaic cell, which generates a current, thus completing the circuit. The current then flows to the transistor output where it activates a load, producing a signal that is sent to the device or system. A good understanding of the operating voltage and current is critical when working with optoisolators. The voltage and current required will vary depending on the load, as well as the environment.

FOD817BSD Fidelity and Performance

The FOD817BSD provides high electrical fidelity, allowing for reliable operation in a controlled environment. Its insulation over a wide temperature range makes it suitable for many applications including military, aerospace, medical, automotive and consumer electronics. The FOD817BSD also features a small form factor, making it ideal for applications with space constraints.

When functional parameters are approached from an angle, the FOD817BSD optoisolator offers excellent performance. Its maximum operating voltage of 1.0VDD and its maximum operating current of 100mA allows for reliable operation in extreme operating conditions. The isolated voltage rating of 1.25kV, combined with its low capacitance allows for higher than expected data transmission speeds. With a temperature range of -40°C to +85°C it can deliver both robust reliability and efficient operation in the most demanding environments.

Typical Applications

FOD817BSD optoisolators are used in a variety of applications where reliable isolation of digital input signals is required. These applications can be found in industrial and domestic automation systems, HVAC and motor controls, consumer electronics, and security systems. It is also ideal for applications where space is an issue but reliable operation is desired.

The FOD817BSD is a versatile optoisolator with a good combination of features for applications requiring digital isolated input. It provides excellent operation for voltage and current ranges, and offers superior fidelity for assured signal transmission. With its range of temperature stability, low leakage and small size, the FOD817BSD is a versatile and reliable choice.
