ISOCOM, Inc. Transistor, Photovoltaic Output Optoisolators IS4N46X

The IS4N46 optocoupler is a low input current device featuring a Darlington output configuration, housed in a standard 6-pin dual in-line plastic package. It is designed to provide high voltage and current capabilities, with a collector-emitter breakdown voltage of 55V and a maximum collector current of 150mA. The device offers a high isolation voltage of 5.3kV RMS and a typical current transfer ratio (CTR) of 1500%, making it suitable for applications requiring robust isolation and signal transfer. This optocoupler operates with a low input current of 0.5mA, which minimizes power dissipation, and includes an internal base-emitter resistor to optimize switching speed and performance at elevated temperatures. It is suitable for various applications, including telephone ring detection, digital logic ground isolation, and interfacing between different logic families. The IS4N46 is UL recognized and compliant with CECC standards, ensuring reliability in critical applications.
