Optoisolators - Transistor, Photovoltaic Output

The PC357M4J000F is a low-power optoisolator that uses a 4 pin DIP packaged transistor to provide electrical isolation between two circuits while maintaining signal transmission. It is a type of optoelectronic isolator, or optocoupler, which conversions electrical inputs into light signals which are then used to control the output of the transistor.

Application Field

The main applications of the PC357M4J000F optoisolator include instrumentation, industrial automation systems, timing and signal processing circuits, automotive electronics, machinery control systems and audio/video devices. These optoisolators are commonly used in industrial settings for a variety of tasks including protecting sensitive electronic components from high voltage transients, providing electrical isolation for motors and other loads from controllers and indexing systems, and providing zero-current turn-on/turn-off control.

The optoisolator can also be used in medical equipment such as medical imaging systems and patient monitoring systems where electrical isolation is required to prevent shock or other hazards. The optoisolator is also suitable for controlling the electrical outputs of a power inverter, allowing the user to safely switch on/off devices that are likely to be in a noisy environment.

Working Principle

The PC357M4J000F has an LED light source inside the package, and an integrated detector. Light from the LED is directed onto an integrated photodetector which generates a current output. This output is then amplified by an internal transistor, which provides isolation between the input and output circuits.

The LED light source is driven by a current of 0.2mA that ranges from 5V to 24V. The output transistor is also driven with a rated current of 20mA over a variation of the same voltage range. The optoisolator has a low propagation delay of only 10µs and a response time of less than a millisecond, allowing it to be used in applications where fast response is required.

The PC357M4J000F optoisolator is designed to provide electrical isolation between two circuits while maintaining a connection between them. It offers excellent noise protection to prevent interference from high frequencies, as well as protection against electrical surges and overvoltage. It is also highly reliable and resistant to aging and environmental changes.
