The 6N137-X009T can operate over a temperature range of -40°C to 100°C.
To ensure reliable operation, it's recommended to derate the device's current transfer ratio (CTR) by 0.5% per °C above 25°C. Additionally, ensure proper heat sinking and thermal management.
The recommended LED forward current for the 6N137-X009T is 10 mA to 20 mA. Exceeding this current may reduce the device's lifespan.
Choose a resistor value that limits the LED current to the recommended range (10 mA to 20 mA) based on the supply voltage and LED forward voltage drop (typically 1.2 V to 1.4 V).
The minimum CTR for the 6N137-X009T is 50% at an LED current of 10 mA and a detector current of 1 mA.
