Description and Introduction

This application note introduces ambient light sensing on a general level. The different types of ambient light sensors are described and related to specific applications. The **SFH2430** is an infrared (IR) emitter manufactured by **OSRAM Opto Semiconductors**. Below are its key specifications, descriptions, and features based on factual information:

### **Specifications:**  
- **Wavelength:** 850 nm (typical)  
- **Radiant Intensity:** 40 mW/sr (minimum at 100 mA)  
- **Forward Current (If):** 100 mA (continuous)  
- **Forward Voltage (Vf):** 1.5 V (typical at 100 mA)  
- **Viewing Angle (2θ½):** ± 25°  
- **Operating Temperature Range:** -40°C to +110°C  
- **Package Type:** Surface-mount device (SMD) in a **PLCC-2** package  
- **Dimensions:** 3.2 mm x 2.8 mm x 2.35 mm  

### **Descriptions:**  
- The **SFH2430** is a high-power **infrared LED** designed for applications requiring strong IR illumination.  
- It is optimized for **high efficiency** and **long operational life**.  
- The **PLCC-2 package** ensures reliable performance in automated assembly processes.  

### **Features:**  
- **High radiant intensity** for improved IR illumination.  
- **Low forward voltage** for energy-efficient operation.  
- **Wide operating temperature range**, suitable for harsh environments.  
- **RoHS-compliant** and halogen-free.  

This IR emitter is commonly used in **surveillance cameras, night-vision systems, and industrial sensors**.
