Optoisolators are electronic components used to electrically isolate two parts of a circuit. They do this by using a light source (usually an LED) to generate a current when an external input is applied. The current generated is then used to control a device within the circuit. An optoisolator like the SFH628A-2X016 is a type of Transistor-Photovoltaic Output optoisolator.

The SFH628A-2X016 has two inputs: an Anode and a Cathode. The Anode input is applied with an externally provided voltage, usually anywhere between 5 and 20 volts, and its corresponding output is a current ranging from 0 to 1 mA depending on the amount of input voltage. The Cathode is used to control the output current when external voltage is applied to the Anode. When no external voltage is applied, the Cathode output is negative.

The SFH628A-2X016 utilizes a Transistor-Photovoltaic Output circuit for its output current. This type of circuit makes use of a photodiode in order to convert the input voltage into a current. The photodiode consists of two parts: an input diode and a transistor. The input diode is the part of the circuit that converts the input voltage into light, and the transistor amplifies this light before it reaches the output. By exploiting the properties of light, the circuit is capable of providing a range of output currents with high accuracy.

The SFH628A-2X016, like most Transistor-Photovoltaic Output optoisolators, is primarily used in safety-critical applications where it is important to maintain a high level of electrical isolation. This optoisolator is commonly found in medical and industrial applications, such as in motor controllers, smoke detectors, and fire alarm systems. It is also used in automotive applications such as in airbag deployment systems and anti-lock braking systems.

The SFH628A-2X016 is versatile and can be used in a variety of applications. Its ability to provide a range of output currents with high accuracy makes it an ideal choice for applications where precision is essential. Additionally, it offers high levels of electrical isolation and can be used in safety-critical systems where preventing the spread of electricity between parts is a must. Additionally, because of its small size, it allows for easy integration into any circuit.
