4N25 Optocoupler IC – DIP Package

The 4N25 is a widely used optocoupler (optoisolator) that consists of a gallium arsenide infrared LED and a silicon NPN phototransistor. It is designed to provide electrical isolation between input and output signals, making it ideal for noise-sensitive and high-voltage applications.

🔧 Key Features

  • 💡 Input Type: Infrared LED
  • 📤 Output Type: Phototransistor
  • Isolation Voltage: 5000 Vrms
  • 🔌 Input Forward Current: 10mA (typical)
  • 📈 CTR (Current Transfer Ratio): 20% to 300%
  • 📦 Package: 6-pin DIP

🧰 Applications

  • Switching power supplies
  • Signal isolation
  • Microcontroller interfacing
  • Data communication
  • Motor control circuits

📦 Package Includes

  • 1 × 4N25 Optocoupler IC – 6-pin DIP

The 4N25 is ideal for isolating low-voltage control systems from high-voltage environments, ensuring safety and signal integrity.
