Optoisolators, sometimes also known as opto-isolators or opto-couplers, are devices which transfer data and signals between two circuits without allowing the two circuits to be electrically connected to each other. The EL3H4(TA)-VG is an optoisolator with transistor, photovoltaic output. This article will provide a comprehensive overview of the EL3H4(TA)-VG application field and working principle.

Application field of EL3H4(TA)-VG

The EL3H4(TA)-VG optoisolator is designed for high performance applications such as audio, automotive, industrial, and consumer products. It offers high isolation voltage (up to 3.5 kVrms) and surge protection (up to 10000 V peak). It also features fast response times (up to 50 ms), low power consumption (down to 4.3 mW) and small package size (down to 3.3 mm x 2.3 mm). The EL3H4(TA)-VG also has a wide operating temperature range (-40°C to +105°C).

The EL3H4(TA)-VG is suitable for a variety of applications, including: automotive systems, medical equipment, consumer appliances, industrial control systems, power supplies, and more. In addition, the optoisolator is also suitable for use in a variety of environments, including high temperature and moisture applications.

Working Principle of EL3H4(TA)-VG

The EL3H4(TA)-VG optoisolator functions by using a transmitter and a receiver. The transmitter is a photodiode (light source), which converts electrical energy into light energy. The light output of the transmitter is then collected by a receiver, which is a phototransistor. The output from the receiver is then converted back into electrical energy.

When the input voltage to the transmitter is increased, the light output will also increase. This light is then collected by the receiver, which in turn creates an output voltage. The magnitude of this output voltage is dependent on the amount of light that is collected by the receiver.

In addition to the transmitter and the receiver, the EL3H4(TA)-VG also contains a LED monitor, which monitors the LED output voltage. This allows the optoisolator to be monitored for any potential failures or malfunctions.

Conclusion

In conclusion, the EL3H4(TA)-VG optoisolator is an effective solution for data and signal transfer between two circuits. It offers a wide range of features, such as high isolation voltage, fast response times, low power consumption, and a wide operating temperature range. The optoisolator also works by using a transmitter and receiver, as well as a LED monitor, which monitors the LED output voltage. Therefore, the EL3H4(TA)-VG is a great choice for those looking for a reliable optoisolator.
