Description and Introduction

LOW DROP POWER SCHOTTKY RECTIFIER The STPS10L40CF is a Schottky rectifier manufactured by STMicroelectronics.  

### **Specifications:**  
- **Voltage Rating (VRRM):** 40V  
- **Average Forward Current (IF(AV)):** 10A  
- **Forward Voltage Drop (VF):** 0.49V (typical) at 5A  
- **Reverse Leakage Current (IR):** 0.5mA (typical) at 25°C  
- **Operating Junction Temperature (Tj):** -65°C to +175°C  
- **Package:** TO-220AB (isolated)  

### **Descriptions and Features:**  
- **Schottky Technology:** Provides low forward voltage drop and fast switching.  
- **High Efficiency:** Optimized for power management applications.  
- **Low Power Loss:** Reduces thermal dissipation.  
- **AEC-Q101 Qualified:** Suitable for automotive applications.  
- **Isolated Package:** Ensures electrical isolation for improved thermal performance.  

This rectifier is commonly used in power supplies, DC-DC converters, and reverse polarity protection circuits.

Application Scenarios & Design Considerations

LOW DROP POWER SCHOTTKY RECTIFIER

Alternative Part Number

  • MBRD1045CT --: Dual common-cathode Schottky rectifier with 10A per leg and 45V rating, close electrical match to the 40V STPS10L40CF in a similar power package.
  • VS-10CTQ045 --: 10A dual Schottky rectifier rated 45V with low forward drop, suitable drop-in replacement for the STPS10L40CF in most rectification circuits.
  • SBR10U45CT --: 10A dual Schottky barrier rectifier at 45V with comparable forward voltage and thermal behavior, offering a slightly higher voltage margin.
