Description and Introduction

Power Schottky Rectifier The STPS20SM100SR is a power Schottky rectifier manufactured by STMicroelectronics (ST).  

### **Specifications:**  
- **Voltage Rating (VRRM):** 100V  
- **Average Forward Current (IF(AV)):** 20A  
- **Peak Forward Surge Current (IFSM):** 200A (8.3ms single half-sine wave)  
- **Forward Voltage Drop (VF):** 0.85V (typical at 10A, 25°C)  
- **Reverse Leakage Current (IR):** 1mA (maximum at 100V, 125°C)  
- **Junction Temperature Range (Tj):** -65°C to +175°C  
- **Package:** TO-247  

### **Descriptions:**  
- Designed for high-efficiency power applications.  
- Low forward voltage drop reduces power losses.  
- High surge current capability for rugged performance.  

### **Features:**  
- **Schottky Technology:** Ensures low switching losses.  
- **Guard Ring Protection:** Enhances ruggedness and reliability.  
- **High Junction Temperature:** Supports operation in harsh environments.  
- **RoHS Compliant:** Meets environmental standards.  

This rectifier is commonly used in power supplies, DC-DC converters, and freewheeling diodes.

Application Scenarios & Design Considerations
