Optoisolators are devices that use optical signals to transmit signals between circuits. They can isolate the input from the output, preventing interference from one circuit to another. EL354N(A)(TA)-VG is a transistor, photovoltaic output optoisolator. It is specifically designed for isolated interface circuits between logic and power control in a variety of types of equipment. This article will discuss the application field and working principle of the EL354N(A)(TA)-VG optoisolator.

Application Field

The EL354N(A)(TA)-VG can be used in high-voltage and high-current systems, such as industrial automation, security, medical devices, and telecommunications. It is also suitable for use in safety applications and harsh environments where visual isolation needs to be maintained and it also provides high optical isolation to prevent ground loops. The EL354N(A)(TA)-VG is designed to be used for driving triac AC switches with logic signals or in other power control applications.

Working Principle

The EL354N(A)(TA)-VG optoisolator consists of a LED emitter and an integrated photovoltaic transistor output which is a Darlington configuration of two NPN transistors. The LED emits light of predetermined wavelength when a DC current is applied to it. The light is then converted to a current by the photovoltaic transistor which triggers the optoisolator. The optoisolator input circuitry is similar to a sense amplifier, which constantly monitors the movement of the LED diode.

When the input signal is applied, the LED emits light which is converted to an electrical current by the photovoltaic transistor and flows through the transistor output to provide the desired switching action. The EL354N(A)(TA)-VG has a high sensitivity of 0.8mA, which ensures enough light is emitted to activate the optoisolator output for a signal range from 0 mA to 5 mA.The EL354N(A)(TA)-VG also provides a wide operating temperature range from –40°C to +100°C, making it suitable for applications in extreme temperature environments. It is also compatible with 10 to 30V AC or DC signals and has an isolation voltage of 5000Vrms.

Conclusion

The EL354N(A)(TA)-VG optoisolator is an ideal solution for isolated interface circuits between logic and power control. It is designed to be used for driving triac AC switches with logic signals or other high-voltage and high-current applications. The optoisolator uses an LED emitter, which is converted to an electrical current by the photovoltaic transistor for signal range from 0 mA to 5 mA. The high sensitivity of 0.8mA, wide operating temperature range, and high isolation voltage make the EL354N(A)(TA)-VG a reliable and reliable optoisolator ideal for a variety of applications.
