SMB Ultrafast Recovery Diodes | 1A~3A | 50V~800V Fast Rectifier

SMB Series

SMB Package Ultrafast Recovery Diodes – High-Speed Switching, 50V~800V, 1A~3A

Product Description
Product Parameters

This series adopts SMB package. With voltage ratings from 50V to 800V and current capacities from 1A to 3A, they offer ultra-fast reverse recovery time (as low as 25ns), low forward voltage drop, and excellent surge current capability.

These diodes are ideal for high-frequency rectification, DC-DC/AC-DC power conversion, motor control, induction heating, and LED lighting systems. Their compact SMB surface-mount package meets the requirements for high-density PCB layout, energy efficiency, and high-speed switching applications.
