B0520WS-7

Overview

The B0520WS-7 is a Schottky barrier diode manufactured by Diodes Incorporated, housed in an SOD-323 surface-mount package. It features a peak repetitive reverse voltage (Vrrm) of 20 V and a maximum continuous forward current (If) of 500 mA. The device exhibits a low forward voltage drop of 430 mV at rated current and a peak non-repetitive forward surge current (Ifsm) of 2 A. Reverse leakage current is limited to 250 μA. Operating temperatures range from -55°C to +125°C junction temperature.

Feature Summary

• Schottky barrier construction for high switching efficiency
• Guard ring design provides transient protection
• Low forward voltage drop minimizes power loss

Applications

• DC-DC converter rectification
• Power supply freewheeling diodes
• Reverse polarity protection circuits

Procurement Notes

Verify the specific ordering suffix against manufacturer documentation to confirm exact electrical tolerances and packaging specifications. Ensure the component meets required RoHS compliance standards for the target application environment. Cross-reference datasheet revisions to validate parameter consistency before finalizing procurement orders.

Selection Notes

Select this component when a compact SOD-323 footprint is required for low-voltage rectification applications. The 20 V rating suits systems with moderate voltage spikes. Evaluate thermal management requirements based on the 500 mA continuous current capability and specified junction temperature limits during circuit design.

Part Context

This part belongs to the B0520WS series of Schottky diodes from Diodes Incorporated. It shares the same electrical characteristics as the B0520WS variant but includes specific manufacturing or packaging identifiers defined by the -7 suffix. The series is designed for general-purpose rectification in space-constrained electronic devices.
