B140WS-7

Overview

The B140WS-7 is a surface-mount Schottky barrier rectifier manufactured by Diodes Incorporated. It features a single silicon element with a peak repetitive reverse voltage of 40 V and an average rectified output current of 1 A. The device exhibits a maximum forward voltage of 0.62 V at 1 A and a maximum reverse current of 50 μA at 40 V. It operates within a junction temperature range of -55 to +150 °C and utilizes an SOD323 package.

Feature Summary

• Low-forward voltage drop for high efficiency
• Guard ring construction for transient protection
• High conductance capability

Applications

• Low voltage, high frequency inverters
• Free wheeling applications
• Polarity protection circuits

Procurement Notes

Verify the specific ordering suffix '-7' corresponds to the 3000-unit tape and reel carrier configuration as documented in the official datasheet. Confirm that the component meets RoHS compliance standards and halogen-free requirements before finalizing procurement specifications.

Selection Notes

Select this component for designs requiring a compact SOD323 footprint with 1 A continuous current handling. Ensure the application voltage does not exceed the 40 V rating and consider the thermal resistance characteristics when designing heat dissipation strategies for the circuit board layout.

Part Context

This part belongs to the B140WS series of surface-mount Schottky barrier rectifiers from Diodes Incorporated. It is designed for general-purpose rectification in space-constrained electronic assemblies. An automotive-compliant variant, designated B140WSQ, is available under a separate datasheet for specialized reliability requirements.

Replacement Considerations

Direct substitutes include other 40V 1A Schottky diodes in the SOD323 package. Verify pinout compatibility and ensure equivalent electrical ratings for forward voltage and reverse leakage current before implementing any cross-brand replacements.
