Optoisolators - Transistor, Photovoltaic Output, are optically isolated electrical components that use a signal source, such as light, to securely transfer an electrical signal from a sending device to a receiving device. The 4N46-500E is a 4-pin optoisolator designed to work in a wide variety of industrial, commercial and consumer applications, and is well suited for signal protection, interface isolation, and low-level signal switching applications.

A typical 4N46-500E working circuit includes a power source, an input signal, and an output load. The power source provides a voltage to the input signal, which triggers the LED. The LED drives the photocoupler, which controls the output transistor. When the input signal is activated, the LED is energized and current flows through the photocoupler. This in turn triggers the output transistor, which supplies enough current to the output load, turning it ON or OFF depending on the type of application.

The 4N46-500E is optimized for operation in both AC and DC environments. Its maximum load current is 100mA, with a minimum load voltage of 5V. It has a forward voltage of 2.2 - 2.8V, a maximum collector to emitter voltage of 60V, and a maximum collector current of 2A. Its capacitance and isolation voltage are rated at 3.3nF and 1500Vrms, respectively.

The 4N46-500E is a versatile and reliable optoisolator for many different applications. It is widely used in digital circuits, providing isolation between microprocessors and peripheral modules, protecting circuitry against short-circuit and overload damage. It is also used in motor control systems to protect against over-voltage and overload, and in inverter systems as a circuit breaker. Additionally, it is widely employed in applications involving switching signals, and in RS-232 and 422 communication systems, providing the necessary signal isolation.

When it comes to signal protection, the 4N46-500E is a reliable and cost-effective option. It has a wide operating temperature range from -40°C to +100°C, making it well suited for demanding industrial applications. Additionally, it is built with state-of-the-art optically isolated electronics, with superior noise immunity and a low power consumption of just 5mA. This makes it well suited for low-power applications, such as those in automotive and consumer electronics. These features make the 4N46-500E a great option for signal protection, interface isolation, and low-level signal switching applications.
