PS2535L-1-F3-A

The PS2535L-1-F3-A optocoupler is classified as a transistor, photovoltaic output optoisolator, which means that it is used to electrically isolate, or couple, two independent circuits. This device also provides a low-cost, high speed solution for electronic noise immunity, safety barrier and noise suppression applications. The PS2535L-1-F3-A mainly consists of an LED and an integrated FET (field effect transistor) housed within a single plastic case, making it a compact package.

Application Field: The PS2535L-1-F3-A optocoupler is ideal for use in industrial applications such as in factory automation, machine tools, robotics and process control. It is used to isolate power supplies, reduce ground loop problems and protect digital and analogue circuits from transient spikes. It can also be used to provide isolated I/O control between two units.

Working Principle: The optocoupler functions by the LED emitting light when the input voltage is applied. This causes the FET to turn on and off in response. The LED is designed to be optically coupled with the transistor, meaning that the LED emits light and this light is detected by the phototransistor. This adjusts the output of the FET accordingly. At the output side, the transistor will be activated or deactivated depending on the intensity of the light from the LED.

The optocoupler has a low capacitance phototransistor and an avalanche rugged output FET, meaning that the device is able to withstand a wide variety of operating conditions. This makes it suitable for applications that require high switching speed and low off-state leakage current. In addition, the device can be used in a variety of temperature ranges due to the far Infrared process which provides superior reliability.

The optocoupler is also available in various forms including relay drivers, analog control, silent switch control and single channel output. It is rated for an input voltage of 3.3~18V and an output voltage of 0.6~30V, making it suitable for a variety of applications. The optocoupler has a wide range of safety ratings including UL, CSA, EN, VDE and IEC standards.

In summary, the PS2535L-1-F3-A optocoupler is a transistor, photovoltaic output optoisolator that is suitable for use in industrial applications due to its ability to provide high speed switching and low off-state leakage current. It has a wide range of safety ratings and is available in various forms including relay drivers, analog control, silent switch control and single channel output.
