Description and Introduction

POWER SCHOTTKY RECTIFIER The STPS140A is a Schottky diode manufactured by STMicroelectronics. Below are the specifications, descriptions, and features based on factual information from Ic-phoenix technical data files:

### **Specifications:**  
- **Type:** Schottky Rectifier Diode  
- **Voltage Rating (VRRM):** 40 V  
- **Average Forward Current (IF(AV)):** 1 A  
- **Peak Forward Surge Current (IFSM):** 30 A (non-repetitive)  
- **Forward Voltage Drop (VF):** 0.49 V (typical at 1 A)  
- **Reverse Leakage Current (IR):** 0.5 mA (maximum at 40 V)  
- **Operating Junction Temperature (Tj):** -65°C to +150°C  
- **Package:** SMA (DO-214AC)  

### **Descriptions:**  
- The STPS140A is a high-efficiency Schottky diode designed for low-voltage, high-frequency rectification.  
- It is optimized for applications requiring low forward voltage drop and minimal switching losses.  
- Suitable for power supplies, DC-DC converters, and reverse polarity protection circuits.  

### **Features:**  
- **Low Forward Voltage Drop:** Enhances efficiency in power applications.  
- **High Surge Current Capability:** Withstands short-duration overloads.  
- **Fast Switching:** Ideal for high-frequency operations.  
- **Low Thermal Resistance:** Improves heat dissipation.  
- **AEC-Q101 Qualified:** Suitable for automotive applications.  

This information is based on STMicroelectronics' official documentation. For detailed application notes or reliability data, refer to the manufacturer's datasheet.
