Optoisolators are a type of electrical isolation device that transfers electronic signals between two otherwise electrically separated circuits. They work by using an optical component to electrically isolate two electrically isolated networks. The 6N137SM is a type of optoisolator from Vishay that is used in logic output applications. In this article, we will be discussing the application area and working principle of the 6N137SM.

The 6N137SM is an optoisolator that is designed to provide high-speed data transmission between two electrically isolated networks. It has an isolation voltage rating of 5 KVrms, which makes it suitable for industrial applications such as motor controllers, diagnostic systems, and distributed temperature sensors. It is also widely used in low-speed data transmission applications, such as remote control systems, security systems, and I/O boards. The 6N137SM is available as an 6-pin DIP package and is designed to operate over a wide temperature range.

The 6N137SM is available with either a logic ‘0’ or logic ‘1’ output. The device has a dual photocoupler consisting of a gallium arsenide infrared LED and a silicon NPN phototransistor. The LED is designed to be driven by a logic signal, which will cause the phototransistor to switch between its two states. This logic signal can be used to control a variety of electrical devices such as relays, switches, and motors. The 6N137SM also has an enable function, which allows the user to switch the device on and off.

The working principle of the 6N137SM is based on the fact that light signals can be used to electronically isolate two isolated networks. When a logic signal is applied to the LED, it emits an infrared beam of light, which is then detected by the phototransistor. The phototransistor then switches between its two states, which is then transmitted to the other side of the circuit. This allows for the data to be transferred between two electrically isolated networks without any electrical connection.

The 6N137SM is a highly reliable optoisolator that offers several advantages over other isolation devices. It provides excellent speed with its wide range of logic inputs, and it has a high isolation voltage rating of 5KVrms, making it suitable for a variety of industrial applications. The device is also available in a 6-pin DIP package and can operate over a wide temperature range. This makes it a great choice for those looking for a reliable means of communication between two isolated networks.
