Description and Introduction

Optocoupler, Phototransistor Output, SOP-4, Mini-Flat Package The SFH690AT is an optocoupler manufactured by Vishay. Below are its key specifications, descriptions, and features:

### **Specifications:**  
- **Isolation Voltage:** 5.3 kV (RMS)  
- **Current Transfer Ratio (CTR):** 50% to 600% (at IF = 5 mA, VCE = 5 V)  
- **Input Forward Current (IF):** 60 mA (max)  
- **Reverse Voltage (VR):** 6 V  
- **Collector-Emitter Voltage (VCEO):** 70 V  
- **Collector Current (IC):** 50 mA  
- **Operating Temperature Range:** -55°C to +110°C  
- **Switching Time (tON/tOFF):** 4 µs / 3 µs (typical)  

### **Descriptions:**  
- The SFH690AT is a high-speed optocoupler with a GaAs infrared LED optically coupled to a phototransistor.  
- It is designed for high-voltage isolation and fast signal transmission in applications requiring electrical isolation.  

### **Features:**  
- High isolation voltage (5.3 kV RMS)  
- High current transfer ratio (CTR)  
- Fast switching times  
- Compact 4-pin DIP package  
- Wide operating temperature range  
- Suitable for digital and analog signal isolation  

This optocoupler is commonly used in power supplies, industrial controls, and communication systems where electrical isolation is required.
