Product Description
Vishay MUR440-E3/54 is a high-performance switching diode featuring a single silicon junction configuration. It supports a maximum forward current of 4 A and can handle peak repetitive reverse voltages up to 400 V. Packaged in a DO-201AD through-hole case, the diode offers robust construction with a moulding compound meeting UL 94 V-0 flammability requirements.
The diode's ultrafast recovery time of 75 ns makes it highly efficient for switching mode power supplies, inverters, and other electronic circuits requiring rapid switching. With a low forward voltage of 1.28 V, it minimizes conduction losses, improving overall electrical efficiency.
Its terminals are matte tin-plated leads, solderable per J-STD-002 and JESD 22-B102 standards, ensuring reliable mechanical and electrical connection. The E3 suffix indicates compliance with whisker test standards (JESD 201 class 1A), supporting long-term reliability in demanding environments.
Typical applications include high frequency rectification and freewheeling in switching mode converters and inverters used in consumer electronics, telecommunications, and computer systems.
Features a glass passivated chip junction for durability. Ultrafast reverse recovery reduces power losses and heat generation. Low forward voltage drop enhances energy efficiency in circuits. High forward surge capability supports transient currents without damage.
Compliant with RoHS and industrial flammability standards ensures environmental and safety compliance. Colour band marking clearly identifies cathode end for correct orientation. Suitable for industrial, laboratory, consumer electronics, and telecommunication applications.
This Vishay switching diode is an essential component for engineers designing power management and high-speed switching circuits, providing reliable performance and robust construction. Explore more semiconductors and Switching Diode options in the Vishay category at EnvMart.
