Optoisolators are a type of optoelectronic device for isolating electrical signals from one circuit to another. The PS8602 Transistor Photovoltaic Output is an optoisolator primarily used for protecting a system from damage caused by dangerous voltages, currents, or capacitive loads. This type of optoisolator is made up of a phototransistor, which is a combination of a light-sensitive transistor and a photodiode. The photodiode converts light energy into electrical energy, while the phototransistor amplifies the current. By using a phototransistor, any interruption in the external power-line due to a sudden overload or high-tension line can be detected immediately without any damage to the optoisolator.

The PS8602 optoisolator features a wide operating temperature range of -40 to +105℃. It is also suitable for use in low-voltage applications with 12V, supplied voltage with the capacity of 35V. This optoisolator has a low profile of 2.5mm, which makes the lightweight design appropriate for portable and embedded sensor applications. It is also designed with low power consumption, typically only 31mW. This optoisolator also features resistance to radiation, which ensures reliable operation in extreme environmental conditions from SMD applications.

The working principle of the PS8602 is quite simple. An incident light source causes the photodiode in the optoisolator to conduct current, which in turn causes a voltage drop across the phototransistor, leading to a change in the transistor’s current conduction. The amount of change in the phototransistor’s current conduction is proportional to the amount of incident light. This change in the current conduction is what ultimately controls the output of the optoisolator.

The PS8602 optoisolator is primarily used in various industrial applications such as protection from over-voltage and over-current in common power supplies, dimming of AC-DC and AC mains lighting, reverse polarity device protection, and supply phase correction. It is also used in telecom equipment and AC line monitoring and controlling in various systems.

The PS8602 optoisolator has proven to be a highly reliable and efficient solution for several applications, making it a popular choice for various applications. Its simple working principle and wide operating temperature range make it the perfect choice for various applications. Additionally, the fact that it is radiation resistant, has low power consumption, and is lightweight, makes it suitable for portable sensors and embedded applications.
