Description and Introduction

SCHOTTKY BARRIER RECTIFIERS The SB4050PT is a Schottky Barrier Rectifier manufactured by PEC (Power Electronics Corporation).  

### **Specifications:**  
- **Voltage Rating (VRRM):** 45V  
- **Average Forward Current (IO):** 40A  
- **Peak Forward Surge Current (IFSM):** 300A  
- **Forward Voltage Drop (VF):** 0.55V (typical at 20A)  
- **Reverse Leakage Current (IR):** 0.5mA (typical at 25°C)  
- **Operating Junction Temperature (TJ):** -65°C to +150°C  

### **Descriptions and Features:**  
- **Package:** TO-247 (3-pin)  
- **Technology:** Schottky Barrier Diode  
- **Low Power Loss:** Due to low forward voltage drop.  
- **High Efficiency:** Suitable for switching power supplies and DC-DC converters.  
- **Fast Switching:** Minimizes switching losses in high-frequency applications.  
- **High Surge Current Capability:** Ensures reliability under transient conditions.  
- **Lead-Free and RoHS Compliant.**  

This diode is commonly used in power supply circuits, inverters, and other high-current applications.

Application Scenarios & Design Considerations

SCHOTTKY BARRIER RECTIFIERS

Alternative Part Number

  • MBR4050PT --: Same 40A 50V Schottky dual-diode in TO-247/TO-3P package with comparable forward voltage and current rating, widely available and pin-compatible.
  • STPS4045CW --: 40A 45V dual Schottky rectifier in TO-247, close electrical equivalent with slightly lower voltage rating that is acceptable in most 50V-rated designs.
  • VS-40CPQ050 --: 40A 50V common-cathode Schottky in TO-247, matches voltage and current class and serves as a direct functional substitute.
