Manufacturer： ['fairchild', 'onsemi', 'rochester']
series introduction
The **FOD817CS Series** is a family of high-performance optocouplers designed to provide reliable electrical isolation and signal transmission in a wide range of applications. These optocouplers integrate a gallium arsenide (GaAs) infrared LED and a silicon phototransistor in a compact, industry-standard 4-pin DIP package, ensuring efficient optical coupling and robust performance. With a focus on durability and precision, the FOD817CS Series is widely recognized for its ability to deliver consistent signal integrity across diverse operating conditions.
One of the key features of the FOD817CS Series is its high isolation voltage, which ensures safe and reliable electrical separation between input and output circuits. This makes it an ideal choice for applications requiring protection against high-voltage transients or noise interference. The series also offers a high current transfer ratio (CTR), enabling efficient signal transmission even at low input currents. Additionally, the optocouplers in this series are designed to operate over a wide temperature range, ensuring stable performance in both industrial and automotive environments.
The compact design of the FOD817CS Series makes it suitable for space-constrained applications, while its robust construction ensures long-term reliability. These optocouplers are commonly used in power supply feedback circuits, where they provide precise voltage regulation and isolation. They are also widely employed in industrial control systems, such as PLCs (Programmable Logic Controllers) and motor drives, where electrical isolation is critical for safety and performance. Furthermore, the FOD817CS Series is a popular choice in telecommunications equipment, medical devices, and consumer electronics, where reliable signal isolation and noise immunity are essential.
In summary, the FOD817CS Series combines high isolation voltage, excellent current transfer efficiency, and a compact form factor to meet the demands of modern electronic systems. Its versatility and reliability make it a trusted solution for designers seeking to enhance system safety and performance across a broad spectrum of industries.
