• Medical

Working Principle

The SFH601-2 optoisolator consists of a high-efficiency GaAlAs LED and a NPN phototransistor. The LED is optically coupled to the phototransistor to form an on/off control device, allowing electrical isolation between the input and output circuits.

When input power is applied, the LED is energized and emits light which is received and detected by the phototransistor, turning it “ON” and allowing the output collector current to flow, providing an output signal. When the input power is turned “OFF”, the LED turns “OFF” and the phototransistor turns “OFF”, stopping the collector current flow and producing an output signal.

The SFH601-2 optoisolator is designed using optimized LED and phototransistor technologies to provide the highest degree of optical isolation. The electrical isolation of 5 kVrms isolation provides a high degree of protection for any input or output circuit, helping to prevent electrical noise or other system interference.

Conclusion

The SFH601-2 optoisolator is an ideal device for applications requiring optical isolation, high peak current load-driving capability, and low forward voltage drop. Its ease of use and economical design features make it a popular choice for a wide variety of applications, including instrumentation, consumer and industrial control, communication, data processing, computer peripherals, and medical.
