6N137

In the world of semiconductor technology, the 6N137 optocoupler stands out as an essential component for various digital applications. Designed for top performance and reliability, this optocoupler is ideal for providing electrical isolation between different sections of electronic circuits while ensuring high-speed data transmission.

What is an Optocoupler?

Optocouplers, also known as opto-isolators, are devices that transfer electrical signals using light waves to ensure electromagnetic isolation. They play a vital role in protecting sensitive components from high voltages or noisy environments while allowing data to pass from one part of a circuit to another. The 6N137 optocoupler is a Through-Hole (THT) component, designed for easy integration into printed circuit boards (PCBs). You can find more options on our Optocouplers Category Page.

Key Features of the 6N137 Optocoupler

• Channel Configuration: Single Channel (Ch: 1)
• Output Type: Logic Output
• Current Transfer Ratio (CTR): 19-50% at If: 16 mA
• Pin Configuration: DIP8 package for simple PCB integration
• High-Speed Operation: Capable of transmitting signals at data rates of up to 10 Mbps

Understanding the Current Transfer Ratio (CTR)

The Current Transfer Ratio (CTR) is a crucial parameter for optocouplers as it defines the relationship between the input current (If) and the output current (Iout). For the 6N137, this ratio ranges from 19-50% at an input current of 16 mA. This means that if you pass 16 mA through the input LED of the optocoupler, the output will provide 19-50% of that current, allowing for efficient signal transmission while maintaining electrical isolation.
