The EL817(D) optoisolator is a transistor, photovoltaic output optoisolator used to provide electrical isolation between inputs and outputs in a wide range of applications, from industrial motor controls to medical equipment. This optoisolator features an ultra-low input current, a 120V AC/DC rated voltage, and low VCE saturation voltage.

The EL817(D) optoisolator consists of an infrared emitting diode, optically coupled to a solid-state photosensitive device. The infrared diode emits light when an electric current is passed through it. This light is then detected by the photosensitive device, which is usually a transistor or FET. When the photosensitive device detects the light, it switches and allows current to flow through the output, thus providing electrical isolation between the input and output.

The EL817(D) optoisolator is commonly used in high-current, high-voltage applications, as it has a 120V AC/DC rated voltage. It is also suitable where the input signal must be isolated from the output circuit, since the input current is extremely low. The low input current allows for minimal power consumption and reliable operation. Additionally, the EL817(D) features a low VCE saturation voltage, which is important for applications where a low output voltage is required.

The EL817(D) optoisolator can be used in a variety of applications, ranging from motor controls to medical equipment. In motor control applications, the optoisolator is used to provide electrical isolation between the control circuitry and the motor, thus ensuring that the control circuitry is not affected by any power fluctuations or surges caused by the motor. In medical equipment, the optoisolator is used to provide isolation between the human body and the device. This ensures that the patient will not be exposed to any voltage potential when using the device.

In short, the EL817(D) optoisolator is a transistor, photovoltaic output optoisolator that is used to provide electrical isolation between inputs and outputs. It is suitable for high-current, high-voltage applications, as it has a 120V AC/DC rated voltage. It features an ultra-low input current, allowing for minimal power consumption, and a low VCE saturation voltage. This optoisolator can be used in a variety of applications, ranging from motor controls to medical equipment.
