Description and Introduction

3A 400V Ultrafast Rectifier The **MURS340T3** is a high-performance, ultra-fast recovery rectifier diode designed for applications requiring efficient power conversion and fast switching. This electronic component is part of the MURS series, known for its low forward voltage drop and minimal reverse recovery time, making it ideal for use in power supplies, inverters, and freewheeling circuits.  

With a maximum repetitive reverse voltage of **400V** and an average forward current rating of **3A**, the MURS340T3 ensures reliable operation in demanding environments. Its ultra-fast recovery characteristics help reduce switching losses, improving overall system efficiency. The diode is housed in a **DO-214AA (SMB)** surface-mount package, offering compactness and ease of integration into modern PCB designs.  

Key features include a **low leakage current** and high surge capability, enhancing durability in high-stress conditions. The MURS340T3 is commonly used in switch-mode power supplies (SMPS), automotive electronics, and industrial equipment where fast switching and energy efficiency are critical.  

Engineers and designers favor this component for its balance of performance, reliability, and cost-effectiveness, making it a practical choice for both commercial and industrial applications. Its robust construction ensures compliance with industry standards, providing long-term stability in diverse operating conditions.

Application Scenarios & Design Considerations

3A 400V Ultrafast Rectifier

Alternative Part Number

  • S3M-E3/57T --: 3 A 1000 V standard recovery SMC rectifier with similar current/voltage class and low-cost availability; verify reverse recovery time if fast switching is required.
  • ES3M --: 3 A 1000 V super-fast recovery SMC rectifier, close electrical match to MURS340T3 with fast trr suitable for high-frequency rectification.
  • BYG23M-E3/TR --: 3 A 1000 V ultrafast avalanche SMC diode offering comparable forward current and fast recovery for similar power supply applications.
