- **Operating Temperature Range (Top):** -40 °C to +85 °C  

### **Description:**  
The **SFH 3211** is a high-speed silicon PIN photodiode optimized for applications in the **near-infrared (NIR) spectrum**, particularly around **850 nm**. It is designed for fast response times, making it suitable for **optical data transmission, light barriers, and industrial sensing applications**.  

### **Features:**  
- **High-speed response** (5 ns rise/fall time)  
- **Low dark current** for improved signal-to-noise ratio  
- **Small package size** (2.4 mm x 2.4 mm x 0.9 mm)  
- **RoHS compliant**  
- **Suitable for industrial and consumer applications**  

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