B0530WS

Overview

The EVVO B0530WS is a Schottky barrier rectifier in the B0520WS through B0540WS series, housed in an SOD-323 surface-mount package. It features a maximum average forward current of 0.5 A and a peak repetitive reverse voltage of 30 V. The device exhibits a low instantaneous forward voltage drop of 0.33 V at 0.1 A and supports a peak forward surge current of 500 A for an 8.3 ms half-sine wave. Operating junction temperatures range from -55 °C to +150 °C with a thermal resistance of 22 °C/W.

Feature Summary

• Guard ring construction provides transient protection capabilities
• Low forward voltage drop ensures high conductance efficiency
• SOD-323 plastic surface mount package design

Applications

• General purpose rectification in consumer electronics
• Power supply input stages
• DC-DC converter freewheeling diodes

Procurement Notes

Verify the specific part number suffix against manufacturer documentation to confirm lead-free status and marking codes. Ensure component authenticity by checking for official distributor authorization. Confirm that the SOD-323 footprint matches your PCB layout requirements before finalizing procurement orders.

Selection Notes

Select this component when a compact surface-mount Schottky rectifier is required for low-voltage applications. The 30 V rating suits 5 V or 12 V systems. Consider the 0.5 A continuous current limit and thermal derating curves for ambient temperature conditions above 25 °C during circuit design.

Part Context

This device belongs to the B05xxWS series of Schottky barrier rectifiers manufactured by EVVO. The series includes variants with different reverse voltage ratings, such as the B0520WS (20 V) and B0540WS (40 V), all sharing the same SOD-323 package and 0.5 A forward current capability.

Replacement Considerations

Direct substitutes must match the SOD-323 package, 30 V reverse voltage, and 0.5 A forward current specifications. Verify pinout compatibility and thermal characteristics before implementation.
