Optoisolators can be classified as Transistor, Photovoltaic Output based on their application fields and working principles. The PS2501-1XSM is one of these. It features an Isolation Voltage rating of up to 6.9 kV, and a Maximum Peak Non-repetitive Forward Surge Current of up to 200 mA. It is composed of an infrared emitting diode, an optically coupled silicon NPN transistor, and a collector-current detector circuit.

The PS2501-1XSM is designed to isolate low-level signals and provide protection for both the devices that generate the signals and those that receive them. The optocoupler works by using light to transfer signals between two insulated circuits. The infrared LED in the optoisolator emits light toward the code coupler portion, which contains the photoreceptive transistor. By controlling the amount of light, the transistor is able to switch between on and off states, allowing it to open and close specific electrical contacts. This allows it to provide electrical isolation while also amplifying the LED\'s current by up to 1000 times.

Due to the optocoupler\'s ability to reduce interference, it is frequently used in signal transmission and communication lines, and has a wide range of applications in industrial and security systems. It is especially useful in cases where synchronizing signals between two sites with different ground potentials is necessary. The optocoupler is also designed to help reduce electromagnetic interference (EMI). This noise can often interfere with signal transmission, resulting in slow communication or data loss.

The PS2501-1XSM is composed of an infrared emitting diode, an optically coupled silicon NPN transistor, and a collector-current detector circuit. The collector-current detector circuit is designed to protect the optoisolator from high-frequency noise and over-current conditions. It is also equipped with a built-in photo-coupler with an insulation voltage of up to 6.9 kV, and a maximum peak non-repetitive forward surge current rating of up to 200 mA. The PS2501-1XSM also features a wide inner insulation distance of 15 mm, and operates at temperatures ranging from -40°C to +105°C.

The PS2501-1XSM is an ideal choice for a wide variety of electronic systems, since it offers high performance and reliability and satisfactory electrical noise immunity. It is a cost-effective and reliable solution for applications that require optocoupled isolation. Due to its low power requirements and wide operating temperature range, it is an excellent option for industrial and security systems where electrical insulation and noise reduction is a priority.
