Optoisolators are components that use optoelectrical components to provide electrical isolation between two circuits. One of the most common types of optoisolators is the Transistor, Photovoltaic Output (EL815(S)(TD)) device. This device is widely used in a variety of applications ranging from industrial control systems to consumer electronics.

The EL815(S)(TD) optoisolator consists of an infra-red LED and a photovoltaic cell in a separate, hermetically sealed package. The LED is driven by the input voltage, which can vary from 3 Vdc to 15 Vdc. As the LED is energized, photons are generated and some of these photons are absorbed by the photovoltaic cell. This causes an electrical current to flow through the photovoltaic cell, thus providing electrical isolation between the input and the output circuits.

The EL815(S)(TD) device can be used in a variety of applications where optical isolation is desirable. For example, it can be used to isolate sensitive control circuits from harsh or noisy environments. Additionally, it can be used to isolate data lines in multi-point systems. By using an optoisolator, it is possible to minimize interference and ensure data integrity.

In addition to providing electrical isolation, the EL815(S)(TD) device can also provide voltage level shifting, ripple filtering, and circuit protection. The photovoltaic cell used in the device can operate over a wide voltage range, from 1.2 Vdc to 30 Vdc. This allows for level shifting between different voltage sources and enables the device to act as a buffer to suppress voltage spikes.

The EL815(S)(TD) device is also very reliable. The hermetic seal protects the components from environmental influences, and the voltage ratings make it highly resistant to electrical damage. In addition, the device has very low power consumption, making it ideal for use in low-power applications.

In summary, the EL815(S)(TD) optoisolator is a versatile device with a variety of applications. It provides electrical isolation between circuits, as well as protection from voltage spikes and interference. Furthermore, it operates over a wide voltage range, is highly reliable, and consumes very little power. For these reasons, the EL815(S)(TD) optoisolator is widely used in a variety of applications, including industrial control systems, data transmission, and consumer electronics.
