The IS357 is an optically coupled isolator with an infrared LED and NPN silicon phototransistor in a dual in-line plastic package, designed for signal transmission between systems of different potentials. It has a current transfer ratio of at least 50% at 5 mA input and 5 V collector-emitter voltage. The device supports an isolation voltage of 3.75 kV RMS and 5.3 kV peak, with a collector-emitter breakdown voltage of 80 V and a maximum collector current of 50 mA. It operates from -55°C to +100°C and is a drop-in replacement for the Sharp PC357.
