Optoisolators - Transistor, Photovoltaic Output

An optoisolator, sometimes called an optocoupler, photocoupler or optical isolator, is an isolating device that employs a short optical transmission path to provide electrical isolation. It operates using the principle of electromagnetism, where electrical signals cause optical changes that produce electric signals on the other side of the device. FODB101 is one type of optoisolator.

Working Principle of FODB101

FODB101 optoisolators use a standard NPN transistor output and internal photodiode with current transfer ratio (CTR) of up to 70%. This isolator uses a special “nearly zero bias” configuration to ensure isolation at all times. When the light emitted by the LED is blocked, a transistor is off and can\'t be activated. The photodiode requires no biasing, and since its response range is relatively narrow, it increases noise immunity.

FODB101 Applications

FODB101 optoisolators are used to provide electrical isolation between circuits in a variety of applications. Some common examples are as follows:

  • Switching circuits – This is a basic application that requires light to turn on a circuit, such as in a switch. Optocouplers are the preferred component due to their high electrical isolation.
  • Industrial control systems – For controlling motor speed or any other type of machine, optocouplers are used to isolate the control electronics from the motor drive.
  • Logic gate driver – Optocouplers provide a high voltage control circuit, isolated from the logic circuit.
  • Communication systems – For transmitters and receivers in telecommunications systems, optocouplers are used to isolate the transmitter circuit from the receiver circuit.
  • Medical devices – Optocouplers can be found in medical equipment, such as monitors, and for isolating sensitive signals from bio-compatible circuits.
  • Analog and digital isolation – Digital isolators are used to isolate digital signals from analog signals. Analog isolators are also available for isolating analog signals from the rest of the system.

FODB101 optoisolators are an ideal solution for applications requiring electrical isolation or noise immunity, due to their high CTR, low on-state current, and nearly zero-bias design. Unlike ordinary optoisolators, FODB101 optoisolators are able to provide higher isolation voltage and power across a wide range of temperatures.

Conclusion

FODB101 optoisolators are an excellent choice for applications that require electrical isolation, noise immunity, and high performance. They provide up to 70% current transfer ratio, low on-state current, and nearly zero-bias design, making them the go-to choice for sensitive circuits. From industrial control systems to medical devices, FODB101 optoisolators are a reliable and versatile solution.
