The MOC81073S optoisolator is a transistor, photovoltaic output opto-coupler designed for use in a variety of applications. This device features a fast photovoltaic transfer gain of up to 20 kHz and low input-capacitance of 1 pF. The device also features a low-bias voltage of 2.5V. The MOC81073S is suitable for use in several applications, including non-inverting logic applications, I/O protection, data isolation, microprocessor I/O isolation and switching applications.

The working principle behind the MOC81073S optoisolator is based on the process of photovoltaic transfer. Photovoltaic transfer (also known as photoconductive gain) occurs when light energy is absorbed by an opto-coupler’s photodiode. This light energy causes electrons to collect in the diode’s gap, creating a positive charge. This positive charge is then transferred to the phototransistor, which switches on and off based on the output current.

The MOC81073S optoisolator uses this photovoltaic transfer to provide electrical isolation between two circuits. This device is capable of isolating circuits with an input of up to 1 mA and an output current up to 50 mA. Additionally, the MOC81073S optoisolator is capable of withstanding transients of up to 15 kV/μs.

The MOC81073S optoisolator is used in a variety of applications. In logic applications, the device is used to provide input isolation from an external source. This allows the logic circuit to operate independently of the external signal, providing a higher level of safety. The MOC81073S optoisolator can also be used in I/O protection, as it is capable of isolating the input from the output and can withstand voltage spikes of up to 15 kV/μs.

The MOC81073S optoisolator is also suitable for use in data isolation applications. This device can be used to isolate a system from the rest of a network, preventing the network’s signals from corrupting the system’s data. The MOC81073S optoisolator is also used in microprocessor I/O isolation and switching applications. The device’s isolation capability and low-bias voltage allow it to be used to switch low-voltage logic signals.

In summary, the MOC81073S optoisolator is a transistor, photovoltaic output opto-coupler designed for use in a variety of applications.
