Description and Introduction

Power Schottky rectifier The STPS40M80CT is a power Schottky rectifier manufactured by STMicroelectronics. Here are its key specifications, descriptions, and features:

### **Specifications:**  
- **Voltage Rating (V_RRM):** 80V  
- **Average Forward Current (I_F(AV)):** 20A per diode (40A for common cathode configuration)  
- **Peak Forward Surge Current (I_FSM):** 300A  
- **Forward Voltage Drop (V_F):** 0.55V (typical) at 20A  
- **Reverse Leakage Current (I_R):** 1mA (typical) at 80V  
- **Operating Junction Temperature (T_J):** -65°C to +175°C  
- **Package:** TO-220AB (isolated tab)  

### **Descriptions:**  
- Dual center-tapped Schottky rectifier in a common cathode configuration.  
- Designed for high-efficiency power applications.  
- Low switching losses and high thermal performance.  

### **Features:**  
- **Schottky Technology:** Ensures low forward voltage drop and high efficiency.  
- **High Surge Current Capability:** Suitable for demanding applications.  
- **Isolated Package:** TO-220AB with an electrically isolated tab for easier mounting.  
- **AEC-Q101 Qualified:** Meets automotive industry standards for reliability.  

This rectifier is commonly used in power supplies, DC-DC converters, and automotive applications.

Application Scenarios & Design Considerations

Power Schottky rectifier

Alternative Part Number
