B5819WS

Overview

The EVVO B5819WS is a Schottky barrier rectifier housed in an SOD-323 surface-mount package. It features a maximum repetitive peak reverse voltage of 40 V and supports an average forward rectified current of 1 A. The device exhibits a typical junction capacitance of 10 pF and operates within a storage and junction temperature range of -55 °C to +150 °C.

Feature Summary

• Metal silicon junction with majority carrier conduction for high efficiency
• Guarding functionality designed for overvoltage protection
• Low forward voltage drop to minimize power loss
• High surge current capability for robust performance

Applications

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

Procurement Notes

Verify the specific part number suffix against official manufacturer documentation to confirm mechanical compatibility and electrical ratings. Ensure the sourcing channel provides valid traceability for the SOD-323 package. Confirm that the component meets required environmental standards before integration into final assemblies.

Selection Notes

Select this component when a low-profile surface-mount Schottky diode is required for 40 V reverse blocking applications. The SOD-323 case size suits space-constrained designs. Evaluate thermal derating curves if operating near the upper temperature limits to ensure reliable forward current handling under load conditions.

Part Context

This component belongs to the B5817WS through B5819WS series of Schottky barrier rectifiers. The series shares identical physical dimensions and general electrical characteristics, differentiated primarily by their maximum repetitive peak reverse voltage ratings. The B5819WS represents the highest voltage variant within this specific lineup.

Replacement Considerations

Compatible substitutes include the B5817WS and B5818WS from the same series, provided the circuit design accommodates their lower reverse voltage ratings of 20 V and 30 V respectively.
