Description and Introduction

6-Pin DIP Photodarlington Output Optocoupler The 4N29SD is an optocoupler manufactured by Fairchild Semiconductor (now part of ON Semiconductor). It is a 6-pin optocoupler that consists of a gallium arsenide infrared LED and a silicon phototransistor. The device is designed to provide electrical isolation between input and output circuits, making it suitable for applications such as signal isolation, switching power supplies, and logic ground isolation.

Key specifications of the 4N29SD include:
- **Isolation Voltage**: 5,300 Vrms
- **Collector-Emitter Voltage (VCEO)**: 30 V
- **Collector Current (IC)**: 50 mA
- **Current Transfer Ratio (CTR)**: 20% minimum at 10 mA input current
- **LED Forward Current (IF)**: 60 mA
- **LED Reverse Voltage (VR)**: 6 V
- **Operating Temperature Range**: -55°C to +100°C
- **Package**: DIP-6

The 4N29SD is commonly used in applications requiring high voltage isolation and reliable signal transmission.
