Optoisolators are electronic components that provide electrical isolation between two circuits, the input and the output, and prevent the passage of power from one circuit to the other. This is useful when controlling sensitive electronic components or isolating different voltages. The HCNW135-300E is a type of optoisolator that uses a transistor and photovoltaic output to provide the isolation. In this article we will discuss the application field and working principle of the HCNW135-300E.

Applications

The HCNW135-300E is mainly used in industrial environments, such as for controlling motor drives, testing equipment, and robotics applications. It is also suitable for switching low voltage signals, such as RS-232 or I2C signals. Because it provides electrical isolation between the input and output, it is also suitable for use in medical and avionics systems that require isolation between different voltage levels.

The HCNW135-300E is also a good choice for automotive control applications. It is designed to meet the automotive EMI/RFI (electromagnetic interference/radio frequency interference) requirements, as well as temperature and humidity range requirements. As an optoisolator, it can provide electrical isolation between the input and output of a circuit, even in high current or high voltage applications.

Working Principle

The HCNW135-300E optoisolator consists of two parts, the input circuit and the output circuit. The input circuit is a LED (light-emitting diode) that is powered by the input voltage. When the LED is powered it emits light, which is then detected by the photovoltaic output on the other side of the optoisolator. This photovoltaic output then generates an output voltage that is used to control the transistor output.

The transistor output is controlled by a resistor network that is connected to the output of the optoisolator. When the input voltage is applied to the LED, the current passing through the resistor network is determined by the input voltage. The resistor network also limits the current flowing from the output circuit, thus stabilizing the output voltage, regardless of the input voltage.

The HCNW135-300E is designed to handle input voltages from 5V to 36V. It has a maximum output current of 500mA and an operating temperature range of -25°C to +85°C. It has a maximum switching frequency of 20KHz, making it suitable for use in high-speed control applications.

Conclusion

The HCNW135-300E is an optoisolator that utilizes a transistor and photovoltaic output, and is suitable for a range of industrial, automotive, and avionic applications. It offers electrical isolation between the input and output circuits, and can handle input voltages from 5V to 36V. It has a maximum output current of 500mA and an operating temperature range of -25°C to +85°C, making it ideal for use in high-speed control applications.
