Description and Introduction

NPN-Silizium-Fototransistor im SMT TOPLEDa-Gehause Silicon NPN Phototransistor in SMT TOPLEDa-Package The SFH320-4 is a high-speed silicon PIN photodiode manufactured by SIEMENS (now part of Osram Opto Semiconductors).  

### **Specifications:**  
- **Type:** Silicon PIN Photodiode  
- **Wavelength Range:** 400 nm to 1100 nm  
- **Peak Sensitivity Wavelength:** 850 nm  
- **Responsivity:** 0.55 A/W (typical at 850 nm)  
- **Dark Current:** 1 nA (max at VR = 5 V)  
- **Reverse Voltage (VR):** 60 V  
- **Capacitance:** 4 pF (typical at VR = 5 V, f = 1 MHz)  
- **Rise Time:** 1 ns (typical at VR = 5 V, RL = 50 Ω)  
- **Fall Time:** 1 ns (typical at VR = 5 V, RL = 50 Ω)  
- **Operating Temperature Range:** -40°C to +85°C  

### **Descriptions & Features:**  
- Designed for high-speed optical communication and sensing applications.  
- Suitable for visible and near-infrared (NIR) light detection.  
- Low capacitance and fast response time make it ideal for high-frequency applications.  
- Hermetically sealed in a metal case for reliability.  
- Commonly used in fiber optic receivers, industrial sensors, and medical equipment.  

For exact datasheet details, refer to the official SIEMENS/Osram documentation.
