Description and Introduction

40V 3A Schottky Discrete Diode in a DO-204AL package The MBR340 is a Schottky barrier rectifier diode manufactured by ON Semiconductor. Here are its key specifications, descriptions, and features:  

### **Specifications:**  
- **Voltage Rating (V_RRM):** 40V  
- **Average Forward Current (I_F(AV)):** 3A  
- **Peak Forward Surge Current (I_FSM):** 80A (non-repetitive)  
- **Forward Voltage Drop (V_F):** 0.55V (typical at 3A)  
- **Reverse Leakage Current (I_R):** 0.5mA (max at 40V)  
- **Operating Junction Temperature (T_J):** -65°C to +150°C  
- **Storage Temperature Range (T_STG):** -65°C to +150°C  

### **Description:**  
The MBR340 is a high-efficiency Schottky rectifier designed for low-voltage, high-frequency applications such as switching power supplies, DC-DC converters, and reverse polarity protection.  

### **Features:**  
- **Low Forward Voltage Drop:** Enhances efficiency.  
- **High Current Capability:** Supports up to 3A continuous current.  
- **Fast Switching:** Minimizes switching losses in high-frequency circuits.  
- **High Surge Current Capability:** Withstands up to 80A non-repetitive surge.  
- **Pb-Free Packaging:** Compliant with RoHS standards.  

The MBR340 is available in industry-standard packages such as **DO-201AD** (axial-leaded) and **SMC** (surface-mount).
