Additional Details

The TLP131G operates with a specified forward current for the input LED. The collector-emitter voltage (VCEO) and isolation voltage are key parameters. The current transfer ratio (CTR) indicates the efficiency of signal transfer from input to output. The device is commonly used in industrial control systems and power supplies where isolation and reliable signal transfer are required.
