Description and Introduction

45V 40A Schottky Discrete Diode in a TO-247AC package The **STPS40L45CW** is a Schottky rectifier manufactured by **STMicroelectronics (ST)**. Below are its specifications, descriptions, and features:

### **Specifications:**
- **Type:** Schottky Rectifier Diode  
- **Voltage Rating (VRRM):** 45 V  
- **Average Forward Current (IF(AV)):** 40 A  
- **Peak Forward Surge Current (IFSM):** 300 A (non-repetitive)  
- **Forward Voltage Drop (VF):** 0.57 V (typical at 20 A)  
- **Reverse Leakage Current (IR):** 1.5 mA (maximum at 45 V)  
- **Operating Junction Temperature (TJ):** -65°C to +175°C  
- **Package:** TO-247  

### **Description:**
The **STPS40L45CW** is a high-efficiency Schottky rectifier designed for low-voltage, high-frequency applications such as power supplies, DC-DC converters, and reverse polarity protection. It features a low forward voltage drop and fast switching characteristics, reducing power losses and improving efficiency.

### **Features:**
- **Low Forward Voltage Drop:** Minimizes conduction losses.  
- **High Current Capability:** Supports up to 40 A average forward current.  
- **High Surge Current Performance:** Withstands 300 A peak surge current.  
- **Fast Switching:** Enhances efficiency in high-frequency applications.  
- **High Temperature Operation:** Reliable performance up to 175°C.  
- **AEC-Q101 Qualified:** Suitable for automotive applications.  

This diode is commonly used in **switching power supplies, inverters, and motor control circuits** due to its robust performance and efficiency.
