B0540WS-7 Description

Short technical summary and product information.

The B0540WS-7 is a Schottky Barrier Rectifier from Diodes Incorporated designed for low forward voltage drop and high efficiency in power rectification applications. It features a peak repetitive reverse voltage of 40V and an average rectified output current of 0.5A. The forward voltage is typically 550mV at 500mA, enabling low power dissipation.

 

This device includes guard ring construction for transient protection and is rated for a non-repetitive peak forward surge current of 3A. It operates over a junction temperature range of -40°C to +125°C and has a thermal resistance of 426°C/W junction-to-ambient.

 

The B0540WS-7 is supplied in a surface-mount SOD-323 package with matte tin plated leads and is available in tape and reel packaging with 3000 pieces per reel. It is RoHS3 compliant, lead-free, and halogen- and antimony-free.
