- **Collector Current (IC):** 50 mA  
- **Current Transfer Ratio (CTR):** 20% to 40% (at IF = 10 mA, VCE = 5 V)  
- **Input Forward Current (IF):** 60 mA (max)  
- **Forward Voltage (VF):** 1.65 V (typical at IF = 10 mA)  
- **Response Time (tON / tOFF):** 3 μs / 4 μs (typical)  
- **Operating Temperature Range:** -55°C to +100°C  

### **Descriptions:**  
- The **SFH600-3** is a high-reliability optocoupler designed for signal isolation in industrial and automotive applications.  
- It consists of a **GaAs infrared LED** coupled with a **silicon NPN phototransistor**.  
- Provides **electrical isolation** between input and output circuits.  
- Suitable for **digital and analog signal transmission** in harsh environments.  

### **Features:**  
- **High isolation voltage (5300 Vrms)**  
- **Fast switching speed** (microsecond response time)  
- **Wide operating temperature range**  
- **Compact DIP-6 package**  
- **Compliant with industrial and automotive standards**  

This information is based solely on the manufacturer's datasheet and technical documentation.
