Description and Introduction

Power Schottky Rectifier The **STPS40120CT** is a Schottky rectifier manufactured by **STMicroelectronics (STM)**. Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:

### **Specifications:**
- **Type:** Dual Schottky Rectifier (Common Cathode)  
- **Voltage Rating (VRRM):** 120 V  
- **Average Forward Current (IF(AV)):** 40 A (per diode)  
- **Peak Forward Surge Current (IFSM):** 300 A  
- **Forward Voltage Drop (VF):** 0.85 V (typical at 20 A)  
- **Reverse Leakage Current (IR):** 1 mA (max at 120 V, 25°C)  
- **Junction Temperature Range (Tj):** -65°C to +175°C  
- **Package:** TO-220AB (isolated tab)  

### **Descriptions:**
- Designed for high-efficiency power conversion applications.  
- Low forward voltage drop reduces power losses.  
- High surge current capability.  
- Suitable for switch-mode power supplies (SMPS), freewheeling diodes, and reverse polarity protection.  

### **Features:**
- **Schottky Technology:** Ensures fast switching and low switching losses.  
- **High Current Capability:** Supports high-power applications.  
- **Isolated Package:** TO-220AB with an isolated tab for better thermal management.  
- **Low Thermal Resistance:** Enhances heat dissipation.  
- **AEC-Q101 Qualified:** Suitable for automotive applications.  

This information is based on the manufacturer's datasheet and technical documentation. For detailed performance curves and application notes, refer to the official STMicroelectronics datasheet.
