Optoisolators - Transistor, Photovoltaic Output

VO618A-4X016 is an optoisolator transistor type photovoltaic output component. It is designed to provide electrical isolation between an output and an input circuit, while maintaining compatibility between the two circuits. The component is extremely helpful in cases where the output and input circuits require different levels of electrical safety and/or need to be separated due to environmental conditions. In such cases, the optoisolator provides a galvanic isolation barrier between the two, while still allowing for a certain level of signal transmission.

The VO618A-4X016 is composed of both an infrared emitters and an NPN phototransistor. It features a non-polar output current of 4 mA and an optically isolated voltage of up to 5.5V. The device is designed to be electrically isolated, but still provide good electrical contact between the output and input. It also has a maximum operating temperature of 85°C.

The device has three main applications. First, it can be used as a level translator between two circuits. This enables the input and output circuits to communicate without interference from other sources. Second, it can be used to detect an external power source, enabling it to automatically switch its circuits from one operating state to another. Third, it can be used to provide over voltage and over current protection in high power applications. This prevents possible damage to connected components due to excessive voltage or current.

The working principle of the VO618A-4X016 is based on its two main components, the infrared emitter and the phototransistor. When an electrical current is applied to the emitter, it emits infrared light. This light is received by the phototransistor, which then converts it to an electrical signal. This signal can then be fed into an input circuit, providing electrical isolation between the two. The components of the optoisolator are arranged so that the output is isolated from the input even if there are wide variations in the input voltage.

In conclusion, the VO618A-4X016 is an optoisolator transistor type photovoltaic output component that is designed to provide electrical isolation between an input and output circuit. It has a maximum operating temperature of 85°C and an optically isolated voltage of up to 5.5V. The device has three main applications, namely level translation, detection of an external power source, and over voltage and over current protection. The optoisolator works by converting infrared light to an electrical signal which can then be fed into an input circuit. This allows it to provide both electrical isolation and a signal transmission between the two circuits.
