Optoisolators - Transistor, Photovoltaic Output are electronic devices that use a photovoltaic (PV) cell to transfer electrical signals between two isolated circuits. They are used in a variety of applications, such as isolating signals in medical equipment, reducing Cross Talk in telecommunications, and providing over-voltage protection in power divisions. PS2802-1-A is one such device.

The PS2802-1-A is a 4-pin pluggable transistor optoisolator. It consists of a high-intensity LED, which is connected between the emitter and collector pins of a bipolar transistor. The collector current activates the transistor, which switches the device ON or OFF. In turn, this activiates the LED at the base, which is connected to the anode pin, generating an output current at the cathode pin.

The PS2802-1-A provides a high degree of electrical insulation between the input and output sides, due to the use of its opto-isolator technology. This technology provides up to 1000 V rms of isolation between the two halves, preventing the input signal from being affected by any noise on the isolated side. Additionally, the PS2802-1-A is designed to be reverse biased, so that when the base voltage exceeds the supply voltage, the transistor turns off, disabling the LED.

The PS2802-1-A is commonly used in various industrial and medical applications, such as alarm systems, power supplies, AC motor control, and patient monitoring. It is also used in automotive applications, such as airbags and seatbelts for safety. Furthermore, it is widely used to isolate signals in telecommunications, allowing them to travel free of interference.

The PS2802-1-A is a versatile and reliable optoisolator, designed to meet the requirements of various industries. It has a wide operating range of -40° to 105°C and high direct current gain of 100. Furthermore, its low operating voltage and power consumption make it suitable for use in battery powered applications. In addition, it has a maximum discharge current of 6mA, ensuring reliable operation.

The PS2802-1-A is an easy to use device, requiring only a few external components to get up and running. It typically operates from a DC supply voltage of 3.3 to 5.5V, depending on the specific application. The LED requires a DC current of 10mA to 50mA, and the collector current ranges from a few milliamps up to 10mA depending on the voltage applied to the base pin.

Overall, the PS2802-1-A is an excellent choice for signal isolation and switching applications. It provides a high level of electrical insulation between the input and output sides, allowing signals to travel between the two without interference or noise. Furthermore, its wide operating range, low power consumption, and low-noise performance make it suitable for a wide range of applications. In conclusion, the PS2802-1-A is an ideal optoisolator for a variety of applications in the industrial, medical, and automotive industries.
