Description and Introduction

6-Pin DIP High BVceo Phototransistor Output Optocoupler The CNY172 is an optocoupler manufactured by **Fairchild Semiconductor** (now part of ON Semiconductor). Here are its key specifications:  

- **Isolation Voltage**: 5000 Vrms  
- **Current Transfer Ratio (CTR)**: 50% (minimum at 10 mA input current)  
- **Input Forward Current (IF)**: 60 mA (maximum)  
- **Reverse Voltage (VR)**: 6 V  
- **Output Collector-Emitter Voltage (VCEO)**: 70 V  
- **Operating Temperature Range**: -55°C to +110°C  
- **Package**: DIP-6 (6-pin dual in-line package)  
- **Turn-On / Turn-Off Time**: 3 μs (typical)  

The device consists of a **GaAs infrared LED** optically coupled to a **silicon phototransistor**, providing electrical isolation between input and output.  

(Note: Fairchild Semiconductor was acquired by ON Semiconductor in 2016, but legacy datasheets may still reference Fairchild.)
