Description:

The PS2701 is a high-reliability optocoupler designed for signal isolation in various electronic circuits. It consists of an infrared LED optically coupled to a phototransistor, providing electrical isolation between input and output.

Features:

• High Isolation Voltage (5,000 Vrms) for safety and noise immunity
• Compact 4-pin DIP package for easy PCB mounting
• Fast switching speed (3 μs typical) for signal transmission
• Wide operating temperature range (-55°C to +100°C)
• High current transfer ratio (CTR) for efficient signal coupling
• Reliable performance in industrial and consumer applications

This optocoupler is commonly used in power supply feedback circuits, microcontroller interfacing, and noise-sensitive applications requiring electrical isolation.
