The 6N139-L is a high-speed photocoupler with a light-emitting diode and integrated high-gain photodetector, designed for digital logic ground isolation and high common mode noise immunity. It comes in an 8-pin DIP package. The device has a typical current transfer ratio of 2000%, a low input current requirement of 0.5 mA, and a TTL-compatible logic low output voltage of 0.4 V. It supports an output collector current of up to 50 mA and a supply voltage up to 18 V, with an operating temperature range of -40 °C to +85 °C. The part provides an isolation voltage of 5000 V rms and meets UL and CSA safety certifications. A 0.1 μF bypass capacitor is required between pins 8 and 5, and base access enables gain bandwidth adjustment.
