The SFH6136 optoisolator is a widely used optocoupler which consists of an infrared light-emitting diode and a phototransistor. This combination of components creates an electrical isolation which offers effective protection from electrical noise and unpredictable transients. Optoisolators play an important role in electrical design projects in the industrial and automotive industries as well as in medical, commercial, and consumer applications.

Application Field

The SFH6136 optoisolator is widely used in applications that require electrical isolation or noise protection. In the automotive and industrial sectors, the optoisolator is employed to provide input protection in electronics systems like relays, thermocouples, and drum switches. With an impressive common mode current specification of 250mA, the SFH6136 is also popular in the medical sector for applications such as inverter-sourced lighting systems and motion control.

SFH6136 optoisolators are also popular in communication applications, including devices such as modems, ISDN, DSL, and DSL filters, as well as other applications such as digital TV systems, HDD write/read control, and PCMCIA applications.

Working Principle

The SFH6136 optoisolator consists of two components: an infrared light-emitting diode (LED) and a phototransistor. The operation of the SFH6136 is based on the principle of photoconductive coupling. When voltage is applied to the LEDs, it emits infrared light which is detected by the phototransistor which has been configured to change its conductivity with the incidence of light.

This change in conductivity of the phototransistor causes a small current to flow on the output, which is an effectively insulated voltage from the input. The strength of this voltage is determined by the intensity of the light emitted from the LED, which in turn is proportional to the amount of electrical current that is being applied to the LED. This makes the SFH6136 useful in applications that require electrical isolation and protection against unexpected and unpredictable transients.

Summary

The SFH6136 optoisolator is a widely used optocoupler that offers high common mode current specification of 250mA. It is used in various industrial and automotive applications such as relays, thermocouples, drum switches, modems, ISDN, DSL, digital TV systems, HDD write/read control, and PCMCIA applications. Its operation relies on the principle of photoconductive coupling where an LED emits infrared light which is detected by the phototransistor. The change in the phototransistor’s conductivity creates a small current that is effectively insulated from the input, thus providing effective electrical isolation and protection from electrical noise and unpredictable transients.
