The working principle of the ACPL-302J-500E isolator is based on a LED array and photo diode array. When the input of the transistor is driven by an input circuit, the LED will be illuminated and the output current is regulated by varying the illumination intensity. The output current will be regulated to the desired value and is then passed to the load through an optocoupler to realize isolation. This way, isolation is achieved between input and output, and the current is closely regulated, making it suitable for most high power output applications.

The ACPL-302J-500E can be used in a variety of applications ranging from power supplies, telecommunication systems, automation and control, industrial gate drive applications, and medical equipment. It is an excellent choice for applications that need high voltage and current isolation, wide voltage and temperature ranges, as well as input and output protections. This device is capable of providing high performance, reliability, and robustness over a wide range of operating conditions, while consuming minimal power.
