Description and Introduction

LOW DROP POWER SCHOTTKY RECTIFIER The STPS2L40U is a Schottky diode manufactured by STMicroelectronics. Here are its specifications, descriptions, and features:

### **Specifications:**  
- **Voltage Rating (V_RRM):** 40 V  
- **Average Forward Current (I_F(AV)):** 2 A  
- **Peak Forward Surge Current (I_FSM):** 50 A (non-repetitive)  
- **Forward Voltage Drop (V_F):** 0.38 V (typical) at 1 A  
- **Reverse Leakage Current (I_R):** 0.5 mA (maximum) at 40 V  
- **Operating Junction Temperature (T_J):** -65°C to +150°C  
- **Storage Temperature (T_STG):** -65°C to +150°C  

### **Descriptions:**  
- **Type:** Schottky rectifier diode  
- **Package:** SMA (DO-214AC)  
- **Configuration:** Single diode  
- **Technology:** ST's advanced Schottky process  

### **Features:**  
- **Low forward voltage drop** for high efficiency  
- **High current capability** in a compact package  
- **Guard ring for enhanced ruggedness** against reverse voltage  
- **Low thermal resistance** for improved thermal performance  
- **Pb-free and RoHS compliant**  

This diode is commonly used in power supply applications, reverse polarity protection, and DC-DC converters.

Application Scenarios & Design Considerations

LOW DROP POWER SCHOTTKY RECTIFIER

Alternative Part Number

  • SS24 --: Schottky diode rated 40V/2A in SMA package, direct electrical and footprint equivalent to STPS2L40U.
  • MBRA240 --: 2A 40V Schottky rectifier in SMA case with similar forward voltage and low leakage, suitable drop-in replacement.
  • B240 --: 40V 2A Schottky diode in SMA package, widely available and functionally interchangeable with the original part.
  • MBR240 --: 2A 40V Schottky barrier rectifier with similar forward voltage and current rating, suitable drop-in replacement.
