Optoisolators are electronic isolation components designed to transfer electrical signals from one circuit to another while isolating the controlling circuit from the controlled circuit. The PS2801C-1-V-F3-L-A is a high voltage optoisolator with a transistor and photovoltaic output. It has a bidirectional optocoupler and operates on continuous input current of 90mA and switching voltage from 5V to 100V. Additionally, it offers a high insulation voltage of 3.75- 27kVrms and a temperature range of -55C to +125C. As it is UL recognized and VDE approved, the PS2801C-1-V-F3-L-A is ideal for applications such as input isolators, power supply isolators, motor controls, automotive hysteresis, voltage monitors, power line monitors, digital communication buses and interface isolation.

The PS2801C-1-V-F3-L-A has a two-channel optoisolator with a PNP Darlington output and a photovoltaic output transistor. The optocoupler can be used for a wide range of input frequencies from 2MHz to 1MHz. When voltage is applied to the emitter of the Darlington, current flow is increased through the collector emitter junction and the photovoltaic output transistor turns on. It is designed to be used in applications that require electrical isolation and the switching voltage between these two circuits can range from 5V to 100V. Additionally, it offers high isolation voltage up to 27kVrms for long-term operation.

The working principle of the PS2801C-1-V-F3-L-A is simple. It consists of an infra-red emitting diode and a photovoltaic output transistor. When the input voltage is applied, the IR emitting diode emits energy in the form of light. This light is then detected by the photovoltaic output transistor and generates a current, which controls the switching of the output from on to off. The device also provides good input-output isolation up to 27kVrms, which helps to reduce EMI (electromagnetic interference). This feature is ideal for applications that require noise reduction, such as automotive engine control and devices where electrical isolation is necessary.

The PS2801C-1-V-F3-L-A is an ideal device for data and signal interfaces, power line monitors, voltage monitors, and other applications that require electrical isolation and excellent noise immunity. It is a reliable and cost-effective way to provide optically coupled isolation, making it an excellent choice for optoisolator applications. Furthermore, its wide operating temperature range, high isolation voltage, fast switching speed, and low input power make it the perfect component for industrial control systems and other applications.
