Introduction

SFH6702-X006 belongs to the family of Optoisolators - Logic Output. They are used to achieve a physical isolation between the input and the output of a circuit. They usually comprise an optocoupler, a phototransistor, and a logic output to provide electrical isolation.

Application Field

The SFH6702-X006 requires a DC supply voltage of 6.2V to 15V. When it operates with an input current of 100mA, its maximum output current is 10mA. The SFH6702-X006\'s phototransistor output supports a current range of 1.5mA to 2.7mA, and its maximum collector-emitter voltage is 80V. It offers fast switching speed of 3 microseconds and wide collector-emitter voltage range of up to 80V. The SFH6702-X006 is suitable for relay control, pulse transformer, inductive load application, THT application as well as general industrial applications like current measurements, small signal reverse isolation and drive circuits.

Working Principle

The SFH6702-X006 consists of an LED and a phototransistor placed in a transparent housing. The LED emits light when a voltage signal is applied across it. The light signal is then captured by the phototransistor, which amplifies the voltage signal before forwarding it to the output. In this way the component provides electrical isolation between the input and the output components.

The LED is typically used to provide an optical link between the input and the output. The phototransistor then acts as a photodetector, converting the light signal into a logic signal. This is then forwarded to the output, where it is converted back to an electrical signal for further use.

Conclusion

SFH6702-X006 belongs to the family of Optoisolators – Logic Output, and they offer fast switching speed and wide collector-emitter voltage range. The component is suitable for relay control, pulse transformer, THT application as well as general industrial applications like current measurements, small signal reverse isolation and drive circuits.
