SFH6326-X017

The SFH6326-X017 is a type of opto-isolator in the Transistor, Photovoltaic Output family. This device combines an infrared emitting diode and a phototransistor to create a reliable visual exchange between two circuits to limit electrical input/output leakage caused by line noise or inductive loading. The opto-isolator is designed with a wide power supply range, which makes it suitable for a wide range of applications.

Functionality

The SFH6326-X017 opto-isolator transfers electrical signals over a gap between input and output terminals. This gap isolates the input and output terminals from one another to prevent electrical input/output leakage caused by external line noise or inductive loading. This prevents the loss of data and improves overall signal quality. Due to the dual-channel nature of the SFH6326-X017 opto-isolator, the device can also transfer signals between circuits with different ground potentials.

Properties

The SFH6326-X017 opto-isolator features a wide power supply range of 4.5V to 18V and can be operated at temperatures from -40°C to +105°C. The device also offers an impressive current transfer ratio of 350 percent, with a low signal transfer time of 1µs. The isolation voltage of the SFH6326-X017 opto-isolator is rated at 5.2kV.

Applications

The SFH6326-X017 opto-isolator is suitable for many different applications including automotive, industrial, security, medical and telecoms. Typical application areas include motor control, power management, data communications and test & measurement. The dual-channel design of the SFH6326-X017 opto-isolator also makes it ideal for applications like active grounding, ground loop isolation and analog signal transfer.

Working Principle

The SFH6326-X017 opto-isolator functions by using an infrared emitting diode and a phototransistor to recognize and transfer electric signals across a gap between two different circuits. When an electrical signal is presented across the emitter, the infrared diode will emit a beam of light which is then detected by the photo-sensitive transistor. This will create a current through the transistor which can be felt across the output circuit. By using this setup, signals can be transferred across long distances without any electrical input/output leakage.

Conclusion

The SFH6326-X017 opto-isolator is an invaluable component for many different applications. Its wide power supply range, impressive current transfer ratio, and low signal transfer time make it suitable for many different uses. This opto-isolator is especially useful in applications like motor control, power management, data communications and test & measurement.
