Overview
The B0540WS-7 is a surface-mount Schottky barrier rectifier manufactured by Diodes Incorporated. It features a single diode configuration in an SOD323 package. The device supports a peak repetitive reverse voltage of 40 V and an average rectified output current of 0.5 A. Electrical characteristics include a forward voltage of 285 mV at 10 mA and 480 mV at 500 mA, with a maximum reverse current of 5 µA at 30 V. It operates within a temperature range of -40°C to +150°C.
Feature Summary
- Low-forward voltage drop for high conductance
- Guard ring construction for transient protection
- Totally lead-free and fully RoHS compliant
Applications
- Surface mount Schottky barrier rectification
- High frequency DC to DC converters
- Polarity protection circuits
Procurement Notes
Verify the specific ordering suffix '-7' corresponds to the tape and reel packaging format containing 3000 units per carrier. Confirm that the component meets the required environmental standards, specifically the halogen and antimony-free 'Green' device definition provided by the manufacturer. Ensure compatibility with the specified SOD323 footprint during procurement planning.
Selection Notes
Select this component for applications requiring low forward voltage drop and high reliability in surface mount designs. Consider the thermal resistance values when designing for power dissipation limits. Verify that the 40 V reverse voltage rating provides sufficient margin for the intended circuit operating conditions. Check if automotive qualification is required, as a separate datasheet exists for the qualified variant.
Part Context
This part belongs to the B0540WS series of surface-mount Schottky barrier rectifiers from Diodes Incorporated. It is designed for general-purpose rectification in compact electronic assemblies. The series utilizes a molded plastic package with UL flammability rating classification 94V-0. The product line emphasizes compliance with international environmental directives.
Replacement Considerations
An automotive-compliant version is available under the separate part number B0540WSQ. Verify if the specific automotive qualification is necessary for the target application before selecting the standard or qualified variant.
