PS2702-1-L-A

Optoisolators are components used in electronics to isolate one side of an electrical circuit from another. They typically comprise an infrared LED which is light-coupled with a phototransistor. When a voltage is applied across the LED, the light passes through and is absorbed by the phototransistor, thus allowing current to flow. The PS2702-1-L-A is one such device.

The PS2702-1-L-A is a transistor photovoltaic optoisolator, with a CTR rating of 500%. It is suitable for a wide range of applications, including signal level conversion, data transmission, safety system control, and motor control. The device is packaged in a dual in-line package with pins of 0.1 inch pitch. It is available in both 3v and 5V versions.

The working principle of the PS2702-1-L-A is quite simple. When a voltage is applied across the LED, the light passes through the LED and is absorbed by a photodiode inside the optoisolator. This causes the phototransistor to turn on, allowing current to flow from the collector to the emitter. The phototransistor can be controlled by varying the voltage applied across the LED, thus providing a level of control over the current flowing through the circuit.

The PS2702-1-L-A has a number of features which make it ideal for many applications. The high CTR rating of 500% ensures accurate signal transfer, while the low current consumption and low power dissipation increase efficiency. The wide operating temperature range of -40°C to 85°C make it suitable for use in a variety of environments. In addition, the device is RoHS compliant and can be used in lead-free soldering systems.

The PS2702-1-L-A is a versatile and reliable optoisolator for many applications. It is well suited for use in a wide range of data transmission, safety system control, motor control and signal level conversion. The wide temperature range, high CTR rating and low power consumption make it an excellent choice for many different applications.
