The PS2502-4 is a photovoltaic optoisolator that has been specifically designed to meet the need for high isolation in a variety of applications. It is a transistor output type optoisolator that can be used in a wide range of applications requiring very high insulation and high current carrying capability. The device is composed of an LED input and a photovoltaic cell output, isolated by a thin dielectric layer. The output of the PS2502-4 can be used to drive a transistor switch that will either open or close the circuit.

The LED input of the PS2502-4 optoisolator is driven by an external power source. When the LED input is ON, the photovoltaic cell output will be switched ON, activating the transistor switch. The transistor switch will then either open the circuit when turned ON, or close the circuit when turned OFF. This makes the PS2502-4 a highly efficient and reliable optoisolator for medium to high voltage applications.

The output current of the PS2502-4 is determined by the operating voltage of the LED input and the response time of the photovoltaic cell output. The PS2502-4 is capable of delivering up to 25mA of output current, making it suitable for a wide range of applications. In addition, the PS2502-4 also has excellent temperature stability, with a temperature coefficient of 0.05%/°C.

The wide common mode transient immunity of the PS2502-4 makes it ideal for use in industrial and automotive applications. It is also suitable for switching applications that require high noise immunity and noise suppression features. The PS2502-4 optoisolator is also UL recognized for up to 6.7KVrms and is designed to meet the requirements of international safety standards such as IEC 60664.

In summary, the PS2502-4 optoisolator is a highly efficient and reliable transistor output type optoisolator with excellent temperature stability. It is capable of delivering up to 25mA of output current and is suitable for a wide range of applications requiring high noise immunity, high isolation, and high current carrying capability. The device is UL recognized for up to 6.7KVrms and meets the requirements of international safety standards such as IEC 60664.
