The 6N137-V-H Optocoupler with Transistor Output is a device made by Lite-On that acts as a galvanic isolator between two separate electrical circuits. It is a through-hole mount component, using an 8 pin DIP package, and has a high insulation voltage of 5kV. The component has a single Channel with a logic output, a propagation delay of 10kV/µs, and a maximum current transfer value of 50mA. The device is used for applications requiring electrical isolation, such as motor and transformer control, power control, AC/DC output protection, and industrial automation.
