Optoisolators are components used to electrically separate circuits while allowing them to communicate. Isolation can help protect a circuit from electrostatic discharge (ESD), noise, and other transients. This type of component prevents power supply problems, and this can help reduce system downtime. The 6N137SMT/R is an application-specific optoisolator, part of the family of logic outputs optoisolators. It was designed for the purpose of switching low-level signal applications.

The 6N137SMT/R is particularly suited for signal transmitting and control applications in which electrical isolation between two parts of a circuit is necessary. It is also particularly useful when managing the high-speeds of logic signals. This optoisolator is in the form of a chip with a 6-pin dual in-line (DIP) package, allowing excellent performance in tight spaces.

The most essential feature of the 6N137SMT/R is its ability to electrically isolate a circuit from input signals, allowing communication between two parts of a circuit while providing total galvanic isolation. Its maximum output current is 100 mA, providing the ability to operate low-level signal lines while maintaining very high isolation levels. The 6N137SMT/R is rated for an isolation voltage of 1 kV and an operating temperature range of - 40 to 85 degrees Celsius.

The 6N137SMT/R optoisolator operates with an integrated logic voltage, typically within ranges of 4.5 to 12 volts, that can be 110mV with a low input-logic current. The 6N137SMT/R optoisolator has a fast bit-rate of 1 Mbps and a low propagation delay, making it suitable for high-speed logic applications. The optoisolator has a very high output CTR (current transfer ratio), with a minimum threshold input current of about 0.2mA. This allows the optoisolator to increase the output current with the input current.

Apart from these general characteristics, there are two important working principles that make the 6N137SMT/R particularly suitable for logical output applications. The first is the presence of an LED inside this optoisolator, which transmits the input signal to the phototransistor. An input current is passed through the LED, which leads to the emission of light. This light is intercepted by a phototransistor, which then sends an amplified version of the original input signal to the output.

The other working principle is the fact that the LED is illuminated when the logic voltage level is at or below the predetermined threshold. The phototransistor acts as a switch, allowing current to flow through it when the LED is illuminated. When the LED turns off, the current will no longer flow through the phototransistor, allowing the circuit’s electrical isolation to remain intact.

The 6N137SMT/R optoisolator is an ideal choice for applications that require electrical isolation, particularly those which involve low-level signal transmission and control. Its high output CTR and low power consumption make it perfect for high-speed logical output applications, and its LED-phototransistor design makes it a great choice for electrical isolation. With its small 6-pin DIP package, the 6N137SMT/R optoisolator can provide excellent performance even in the most compact designs.
