B0520WS-7-F

Overview

The B0520WS-7-F is a surface mount Schottky barrier rectifier manufactured by Diodes Incorporated. It features a peak repetitive reverse voltage of 20 V and an average rectified output current of 0.5 A. The device operates within a temperature range of -55°C to +125°C. Electrical characteristics include a maximum forward voltage drop of 0.430 V at 0.5 A and a maximum leakage current of 250 μA at 20 V reverse bias. The component utilizes a SOD323 package with matte tin plated leads.

Feature Summary

• Guard ring die construction provides transient protection capabilities
• Totally lead-free, fully RoHS compliant, and halogen/antimony free green device
• Qualified to JEDEC standards for high reliability applications

Applications

• General purpose rectification in consumer electronics
• Power supply circuits requiring low forward voltage drop
• DC-DC converter input or output stages

Procurement Notes

Verify the specific ordering suffix '-7-F' corresponds to the tape and reel packaging configuration containing 3000 units per carrier. Confirm that the procurement channel is authorized to ensure compliance with standard terms and conditions. Check for any recent product change notices regarding manufacturing facilities or material composition updates prior to finalizing orders.

Selection Notes

Select this component when a low forward voltage drop is required to minimize power loss in rectification paths. Ensure the application voltage does not exceed the 20 V peak repetitive reverse rating. Consider the thermal resistance of 426 °C/W and derating curves if operating near the maximum junction temperature limit of 125°C.

Part Context

This part belongs to the B0520WS series of surface mount Schottky barrier rectifiers from Diodes Incorporated. It is designed as a high conductance alternative to standard silicon rectifiers, offering faster switching speeds and lower power dissipation. The SOD323 package allows for compact PCB layouts in space-constrained electronic designs.

Replacement Considerations

For automotive applications requiring specific change control, refer to the related automotive grade (Q-suffix) parts listed on the manufacturer's website. Verify pinout compatibility and electrical ratings against existing designs before substituting.
