Optoisolators are devices used to provide electrical isolation between two circuits or components, and they are available in a variety of types such as, transistor-output, photovoltaic-output, photointerrupters, and analog optoisolators. Among them, the HCPL-073L-060 is a very powerful photovoltaic-output optoisolator devices that can provide electrical isolation between two circuits at high voltages, with very high insulation resistance and minimum leakage current.

The HCPL-073L-060 devices are manufactured by Hewlett-Packard, and they are designed for a variety of different application fields. These devices have either an AC or DC input voltage range, and they can be used for direct or switching application. The HCPL-073L-060 is particularly useful in applications where safety is a concern, and when controlling devices with voltages beyond the capability of digital logic devices. The HCPL-073L-060 are also widely used in microprocessor systems, motor control circuits, high voltage circuits, and industrial automation systems.

The HCPL-073L-060 devices are designed to provide high levels of electrical insulation, with a working voltage of 20 kVrms, and a maximum insulation resistance of up to 1000 GΩ. Moreover, they have very low noise levels and negligible leakage current (less than 0.1 µA). The packages of the HCPL-073L-060 are also designed to be very narrow, so they can be used in very tight spaces.

The working principle of the HCPL-073L-060 devices is based on the concept of photoconductive isolation. The package contains an LED (light-emitting diode) and a photodiode that are mounted on the same substrate, separated by a very thin dielectric layer. When electrical current is applied to the LED, a high-intensity light is emitted, which is absorbed by the photodiode and converted into electrical current. This electrical current is then electronically amplified, providing the required isolation between two circuits. The HCPL-073L-060 is also available with a shielding option, which ensures that the LED and photodiode are kept at the same potential, further enhancing the level of electrical isolation.

The HCPL-073L-060 devices offer not only electrical insulation but also fast response times and low power consumption. They have an on-state response time of less than 10ns, and their typical operating current is around 5 mA. Another advantage of this type of optoisolator is that it can be used to drive high-current loads, with a maximum drive current of up to 300 mA.

In conclusion, the HCPL-073L-060 devices are very versatile and powerful photovoltaic-output optoisolator devices, which can be used in a variety of applications for reliable electrical insulation and fast response times. They are also suitable for use in microprocessor systems, motor control circuits, high voltage circuits, and industrial automation systems. They offer very high isolation resistance and low leakage current, as well as fast response times and low power consumption.
