Optoisolators are devices used for electrical isolation, which consists of a high impedance beam-splitting optical interface separating the two electrically isolated parts of a circuit. The IL300-E-X006 is an optoisolator from Renesas which features a transistor, photovoltaic output. In this article we will discuss its application field and working principle.

Application Field

The IL300-E-X006 is designed for use in applications that require electrical isolation between two parts of a circuit. The device can isolate signals with low speeds, AC/DC voltage inputs and switches, IoT sensors, automotive power/gate drives, and industrial pumps and motors. With an isolation voltage of up to 5000Vrms, it is suitable for use in high voltage applications. The device features a low power consumption and a wide operating temperature range of -40°C to 125°C, making it ideal for use in harsh environments. Furthermore, it has a solderability of 260°C making it easy to integrate with other components in a circuit.

Working Principle

The IL300-E-X006 consists of an opto-isolator and a transistor output stage. It works by using an infrared LED and a photovoltaic cell as the two electrically isolated parts of the circuit. The LED transmits light from the input side of the circuit, which is then detected by the photovoltaic cell on the output side. When the photovoltaic cell detects the light, it produces a voltage that switches the transistor in the opto-isolator on. This allows current to flow to the output, powering the load connected to it. When the light is removed, the transistor is switched off, disconnecting the load from the power source.

Conclusion

The IL300-E-X006 from Renesas is an opto-isolator featuring a transistor, photovoltaic output. It is designed for use in applications that require electrical isolation between parts of a circuit, with an isolation voltage up to 5000Vrms. The device features low power consumption and a wide operating temperature range, making it ideal for use in harsh environments. Its working principle relies on an infrared LED and a photovoltaic cell that are electrically isolated, which allows current to flow to the output when light is detected.
