Optoisolators - Logic Output

The PC900V0YSZXF Optoisolator is an advanced logic output optoisolator with photo MOSFET output transistor and TTL compatible logic input. An optoisolator is a device comprising a low current-carrying light source which is optically coupled to one or more detector circuits. It provides electrical isolation between the two circuits, allowing circuits to operate at different voltages and with different common mode levels, while providing protection against both overvoltage transients and EMI/RFI noise. The PC900V0YSZXF is suitable for applications requiring fast response, low power consumption, and a wide operating temperature range.

Application Fields

The PC900V0YSZXF Optoisolator is typically used in digital and logic systems, such as embedded microcontrollers, programmable logic controllers (PLCs), and microprocessors, to transfer logic signals across isolation barriers. Its dual-channel configuration allows multiple functions to be performed, including output transistor activation, input signal detection, and open/short LED circuit detection. Applications include industrial automation, medical equipment, aerospace systems, and any other applications in which isolated logic signals are necessary.

Working Principle

The PC900V0YSZXF Optoisolator operates on the principle of transfer of an electrical signal from the input side to the output side through light. A current carrying LED on the input side is illuminated when a logic signal is applied, which causes an optical flux across the gap between the two sides. The photodetector components on the output side convert the optical flux to an electrical current, providing current or voltage output. The electrical isolation between the input and output sides is provided by the light-based transfer mechanism, preventing any direct electrical connection between the two sides. The optoisolator also features a photo MOSFET output transistor, which is able to switch rapidly and draws significantly less power than a regular MOSFET.

Advantages

The PC900V0YSZXF Optoisolator provides many advantages over traditional methods of transmitting logic signals, such as the use of direct electrical connections and voltage level shifters. It offers excellent noise robustness and low-power operation, with a maximum power requirement of only 0.2 W. The transfer of signals across the PC900V0YSZXF is isolated from direct electrical connection, eliminating the need for additional components such as transformers, opto-isolators, and current limiting resistors. The dual-channel configuration has the advantage of reducing the level of wiring complexity, as a single device can achieve the same function as several discrete components.

Conclusion

The PC900V0YSZXF Optoisolator is a versatile logic output optoisolator with a TTL compatible logic input and photo MOSFET output transistor. It is designed for fast response and low power consumption, with a wide operating temperature range. The device provides excellent noise robustness and electrical isolation between the input and output sides, allowing safe and reliable signal transfer. Its dual-channel configuration reduces wiring complexity and eliminates the need for transformer or opto-isolator components, making it ideal for applications requiring isolation and reliable logic signal transfer.
