Description and Introduction

N-channel With built-in flywheel diode The SMA5105 is a surface-mount Schottky barrier diode manufactured by SK (Sanken Electric Co., Ltd.). Below are its key specifications, descriptions, and features based on available knowledge:

### **Specifications:**  
- **Type:** Schottky Barrier Diode  
- **Package:** SMA (DO-214AC)  
- **Maximum Reverse Voltage (VR):** 100V  
- **Average Forward Current (IF):** 5A  
- **Peak Forward Surge Current (IFSM):** 150A (non-repetitive)  
- **Forward Voltage (VF):** 0.85V (typical at 5A)  
- **Reverse Leakage Current (IR):** 0.5mA (max at 100V)  
- **Junction Temperature (Tj):** -55°C to +150°C  
- **Storage Temperature (Tstg):** -55°C to +150°C  

### **Descriptions:**  
- Designed for high-efficiency rectification in switching power supplies, DC-DC converters, and reverse polarity protection.  
- Low forward voltage drop ensures minimal power loss.  
- Fast switching performance suitable for high-frequency applications.  

### **Features:**  
- **Low VF:** Optimized for energy efficiency.  
- **High Surge Current Capability:** Robust performance under transient conditions.  
- **Lead-Free & RoHS Compliant:** Environmentally friendly.  
- **High Reliability:** Suitable for industrial and automotive applications.
