MURD320T4

MURD320T4 Description

The MURD320T4 is a high-performance ultra-fast recovery diode from onsemi's SWITCHMODE™ series, designed for demanding power electronics applications. With a 200V reverse voltage (Vr) and 3A average rectified current (Io), it offers robust performance in compact DPAK (TO-252) surface-mount packaging. This diode is optimized for fast switching with a reverse recovery time (trr) of just 35ns, minimizing power losses in high-frequency circuits. Its low forward voltage drop (950mV @ 3A) and leakage current of 5µA @ 200V ensure high efficiency and thermal stability.

MURD320T4 Features

• Ultra-Fast Recovery: 35ns trr ensures minimal switching losses, ideal for high-frequency applications.
• High Current Handling: 3A continuous current with 200V blocking voltage for robust power management.
• Low Power Dissipation: 950mV max Vf @ 3A reduces conduction losses, improving system efficiency.
• Surface-Mount DPAK Package: Compact and suitable for automated assembly, complying with MSL 1 (unlimited) moisture sensitivity.
• Reliable Performance: REACH unaffected and EAR99 ECCN compliant, ensuring global usability.
• Optimized for SMPS: Part of the SWITCHMODE™ series, tailored for switch-mode power supplies (SMPS) and DC-DC converters.

MURD320T4 Applications
