Optoisolators - Transistor, Photovoltaic Output are quickly becoming an indispensable part of many industries, from medical and automotive to aerospace and consumer electronics. Although this type of component does not output electricity itself, it provides important isolation protection and digital control capabilities that simplify the design and operation of many systems.

The PS2706-1-A is an optoisolator primarily designed for digital on/off signal applications, and it is built with an infrared photo-IC (photo-coupler) and a built-in monolithic DC-DC converter. It helps protect the control and logic circuits from EMI/ESD while also providing high-frequency noise rejection and excellent isolation protection.

The application field of the PS2706-1-A is wide, and it can be employed in any circuit that requires a signal transfer between two or more isolated circuits, such as between the switching power supply circuit and the control circuit in PC power supplies, or between the control circuit and a remote control circuit in other systems.

The working principle behind the optoisolator’s use is based on optocoupling, which involves the use of two different semiconductor components—a light emitting diode (LED) and a photosensitive device. When an electrical current is applied to the LED, it emits light that activates the photosensitive device. The switching mechanism of the two components is what allows the electric current to pass from one side of the circuit to the other without completing a full circuit, resulting in complete electrical isolation between the two sides.

The PS2706-1-A’s built-in DC-DC converter takes the high voltage system output signal and reduces it to a level compatible with the input requirements of the photo-coupler, providing isolation between the two, protecting them from EMI/ESD and providing the highest level of noise immunity.

The PS2706-1-A also features excellent signal integrity, excellent thermal design, and high speed switching, allowing it to perform in a wide temperature range, from -40°C to +85°C. This makes it an ideal choice for use in automotive and electronic devices as well as medical and darkroom imaging equipment.

The PS2706-1-A’s performance and features make it the ideal optoisolator for many applications in a variety of industries. It offers high-speed switching and excellent isolation protection, while also providing the highest level of noise immunity and ensuring signal integrity.
