6N137-360E

Optoisolators are designed to electrically insulate one circuit from another, usually by using a light-emitting diode (LED) to drive an optically coupled semiconductor. The 6N137-360E is a popular optoisolator that belongs to the Logic Output family, meaning it is designed to provide isolation between two circuits and to transfer a digital logic signal from one side to the other. Its application field and working principle are deals discussed in this article.

The 6N137-360E is designed for applications where electrical isolation is desirable, such as switch-mode power supplies, digital isolators, and other monitoring and control systems. It is especially suited for isolating low-level logic signals in environments with high transient voltages or noise. The data sheet of the 6N137-360E states that it provides a high-degree of buffering so that the logic output signal from the source circuit is precisely passed through to the subsequent circuit.

The 6N137-360E consists of two main components: a LED and an optically coupled NPN transistor. The LED is used as the light source for the opto-coupler and is internally connected to the NPN transistor, which is used as the output element. When a logic signal is sent to the LED from the source circuit, the light emitted from the LED is directed to and detected by the transistor, which then amplifies and sends the logic signal to the subsequent circuit.

The 6N137-360E also features high input-to-output isolation voltage, which is key for minimizing the effect of noise or other interference on the logic signal. It also has a wide operating temperature range, so it can be used in systems that are exposed to extreme temperature conditions. The device also provides excellent temperature stability, which helps maintain the accuracy of the logic signal.

In addition, the 6N137-360E has low input-capacitance, so that even low-level signals can be accurately transmitted from the input circuit to the output circuit. This is important for applications that require sensitivity to even the slightest change in signal levels, such as motor controls and smart sensors. Finally, the device has low power consumption, allowing it to be used in battery-powered applications without draining the battery too quickly.

The 6N137-360E is a popular opto-isolator because of its application flexibility, robust features, and low power consumption. It is well-suited for a variety of applications, including switch-mode power supplies, digital isolators, DC-DC converters, motor controls, and smart sensors. Its wide operating temperature range and excellent temperature stability make it suitable for a range of environmental conditions, and its high input-to-output isolation voltage helps ensure accurate data transmission. The device also features low input-capacitance, providing a low, non-attenuating logic signal transmission.
