IL388DAA-00T

Optoisolators - Transistor, Photovoltaic Output

The IL388DAA-00T optoisolator is a photovoltaic transistor output device used for isolating differences in voltage levels between circuits. It is a versatile device used for a variety of applications. The device consists of a gallium arsenide infrared emitting diode (IRED) opposite a high-gain integrated collector silicon phototransistor.

Application Field

The IL388DAA-00T optoisolator is mainly used for digital IC switching control, signal processing, motor speed control, and semiconductor current limit protection systems. It can also be used in computer peripheral interfaces, electronic manufacturing equipment, navigation and factory automation systems, medical equipment, robotics, automotive applications, and audio-video equipment.

Working Principle

The IL388DAA-00T optoisolator contains a gallium arsenide infrared emitting diode (IRED) and a high-gain integrated collector silicon phototransistor. When voltage is applied to the input of the optoisolator, it causes current to flow through the IRED. This results in the production of photons, which are received by the phototransistor. This causes a voltage to be generated in the output circuit with the same polarity as the incoming voltage.

The IL388DAA-00T optoisolator offers superior performance and isolation. It has a very high insulation resistance, up to 500Vdc with a minimum 10mA of current, and excellent long-term stability with no deterioration of performance over years of operation. The optoisolator also has a very low current transfer ratio (CTR) and is suitable for applications requiring very high reliability.

Conclusion

The IL388DAA-00T optoisolator is a versatile, high-performance device that can be used for a variety of applications. It consists of an infrared emitting diode and a phototransistor and is capable of providing long-term stability and excellent isolation. With its low current transfer ratio, it is well-suited for applications requiring high reliability.
