Description and Introduction

40V 3A Schottky Discrete Diode in a D-Pak package The MBRD340 is a Schottky rectifier diode manufactured by Diodes Incorporated.  

### **Specifications:**  
- **Voltage Rating (Vrrm):** 40V  
- **Average Forward Current (Io):** 3A  
- **Peak Forward Surge Current (Ifsm):** 80A  
- **Forward Voltage Drop (Vf):** 0.55V (typical at 3A)  
- **Reverse Leakage Current (Ir):** 0.5mA (typical at 40V)  
- **Operating Junction Temperature (Tj):** -65°C to +125°C  
- **Package Type:** DPAK (TO-252)  

### **Descriptions and Features:**  
- **Schottky Barrier Diode:** Provides low forward voltage drop and fast switching.  
- **High Efficiency:** Suitable for high-frequency applications.  
- **Low Power Loss:** Reduces heat generation in circuits.  
- **Surface Mount Package:** DPAK (TO-252) for easy PCB mounting.  
- **Applications:** Used in power supplies, DC-DC converters, reverse polarity protection, and freewheeling diodes.

Application Scenarios & Design Considerations

40V 3A Schottky Discrete Diode in a D-Pak package

Alternative Part Number

  • STPS340U --: Same 3A 40V Schottky diode in DPAK package with comparable forward voltage and switching characteristics, widely available and pin-compatible.
  • VS-30BQ040 --: 40V Schottky rectifier in DPAK with similar current rating and low forward drop, suitable drop-in replacement for most MBRD340 applications.
  • SS34 --: Common 3A 40V Schottky diode available in DPAK/SMC variants, low cost and broadly stocked, adequate for general rectification where exact package match is confirmed.
