Optoisolators, also known as optocouplers, are electrical components used to isolate two circuits electrically and optically while transferring a signal from one circuit to the other. The HCPL-073L-000E is a photovoltaic output transistor optoisolator which provides electrical isolation between two electronic devices while transfering a signal from one circuit to the other.

The HCPL-073L-000E features an optically coupled structure of an LED and a phototransistor mounted side-by-side in a compact 8-pin flat pack package. It is DC isolated and encapsulated in a thermally conductive plastic housing. This optoisolator is widely used in a variety of applications, as it has a high degree of circuit isolation and low leakage current.

The working principle of the HCPL-073L-000E is quite simple. It consists of an LED coupled to a phototransistor. When the LED is powered from an external source, it emits photons within its specified radiation spectrum. If these photons hit the base region of the phototransistor, they will be absorbed and cause the emitter-base junction to go into the conductive region. This will cause the collector current to flow, thereby providing a switch action between the two circuits.

The HCPL-073L-000E is mainly used for data transmission and communications. It can also be used in AC and DC motor control, solid-state relay applications, as well as medical, industrial, and automotive systems. It is also used in isolated control circuits and in noise-sensitive systems. It provides higher circuit isolation voltage and lower off-state output leakage current.

Overall, the HCPL-073L-000E is a versatile and reliable optoisolator which is ideal for a variety of applications. It is a compact, cost effective device that provides reliable electrical isolation between two circuits, while allowing for the transfer of signals. It is reliable, robust and provides superior circuit isolation, making it an ideal choice for both commercial and industrial applications.
