Optoisolators, also known as optocouplers or photocouplers, are electronic components used to isolate electrical circuits from each other. Typically, isolated electronic components are used in a variety of applications from medical and safety-related systems to industrial automation and power supplies. The JAN4N22U, in particular, is a optoisolator that uses a transistor, photovoltaic output.

JAN4N22U Application Field

The JAN4N22U Optoisolator offers a robust, low-cost solution for isolating up to two circuits. It is characterized by a Transfer Ratio (TR) of up to 200%. This means that the device efficiently transfers electrical signals from one circuit to another, while providing up to 200% isolation. This isolation prevents electrical energy from one circuit from interfering with signals from the other circuit.

The JAN4N22U is designed to handle both DC and AC signals, making it ideal for a wide range of applications. It is well-suited for use in power supplies, motor control systems, and industrial process and automation systems, as well as in audio, video, and data processing systems. In addition, the device can be used in safety-related systems, such as those used in medical equipment.

JAN4N22U Working Principle

The working principle of the JAN4N22U is based on a photovoltaic (PV) output. This type of optoisolator uses an infrared light-emitting diode (LED) to transmit an electrical signal across a gap in two circuits. The signal is converted into an output signal in the form of a photovoltaic current in the photovoltaic receptor on the other side of the gap that is connected to the output circuit. This photovoltaic current is then used to switch the output transistor, which in turn switches the output circuit.

The JAN4N22U optoisolator is designed to operate over a wide voltage and current range. The device is capable of switching loads up to 500mA with up to 10V of voltage. It is also designed to operate over a temperature range of -40°C to 85°C with no breakage. The device can switch speed is also very fast, with typical rise and fall times of 8 microseconds.

The optoisolator also boasts a high level of isolation. It is designed to have an isolation voltage of up to 5kV, which means that unwanted electrical signals cannot cross the gap between the two circuits. This ensures that the signal from one circuit is not affected by the signal from the other. In addition, the device has a high level of noise protection, allowing it to operate even in harsh environments.

Conclusion

The JAN4N22U Optoisolator offers an efficient, affordable solution for isolating two electrical circuits. It is designed to handle DC and AC signals, making it suitable for a wide range of applications. In addition, the device has a high level of isolation and noise protection, allowing it to work in harsh environments. These features, combined with its fast switching speeds and wide temperature range, make the JAN4N22U an ideal choice for isolated electronic components.
