Introduction

The EL816 Optoisolator, manufactured by ROHM Semiconductor, is a transistor output optoisolator. It includes an LED for light emission and a photovoltaic detector, both of which are encapsulated in a single four-pin package. It offers 1500 Vrms of insulation voltage and it is compliant with the safety regulations in various installation environments.

Application Field

The EL816 Optoisolator is specifically designed for electronic equipment which requires optical insulation between electrical wiring. It is intended for mixed signal, power signal circulation and even biasing applications, as well as for power-driving insulation applications. The EL816 is perfect for applications in industrial machinery, such as factory automation, control panels, medical equipment, elevator control systems, security systems, etc. Additionally, it can be used in any applications in which the input electrical signals are optically isolated from the output elements, providing maximum immunity to noise and leakage paths.

Working Principle

The EL816 Optoisolator consists of a photovoltaic detector and an LED in a single package. When a current flows through the LED, light is emitted. This optical signal is then received by the photovoltaic detector, which converts it into an electrical signal, providing isolation between the input circuitry and output circuitry of the device. The photovoltaic detector provides a transistor output that can be used to drive a load.The EL816 is designed with a high level of insulation resistance, providing 1500 Vrms of insulation voltage across the photo-sensitive parts. The switching speed is determined by the LED current and the collector current, however the typical rise and fall times are 10 μs and 5 μs respectively.In addition, this optoisolator can be used in low current drive applications as well, as it is able to support current leakage up to 5 μA. Moreover, it is designed with a maximum current consumption of 20 mA.

Conclusion

The EL816 Optoisolator by ROHM Semiconductor is a transistor output optoisolator that is designed for low-current, mixed signal, power signal circulation, and power-driving insulation applications. It provides 1500 Vrms across the photo-sensitive parts, while supporting current leakage of up to 5 μA. The typical rise and fall times are 10 μs and 5 μs respectively, while the maximum current consumption of the device is 20 mA. This device is perfect for applications in industrial machinery, such as factory automation, control panels, medical equipment, and more.
