BAT42WS-E3-18

Single Diodes Overview

The BAT42WS-E3-18 is a silicon Schottky barrier rectifier manufactured by Vishay General Semiconductor - Diodes Division. It features a maximum repetitive peak reverse voltage of 30 V and an average forward rectified current of 200 mA. The device utilizes a surface-mount SOD-323 package, ensuring low thermal resistance and efficient heat dissipation. Key electrical characteristics include a maximum DC reverse voltage of 30 V, a forward voltage of 1 V at 200 mA, and a reverse leakage current of 500 nA at 25 V. The component operates within a junction temperature range up to 125°C and complies with RoHS standards.

• Free-wheeling diodes in low-voltage DC-DC converter topologies
• OR-ing applications in battery-powered portable devices

Single Diodes Procurement Notes

Verify the specific suffix E3-18 corresponds to the required reel packaging configuration, as suffixes often dictate tape-and-reel quantities rather than functional changes. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the sourcing channel provides traceable lot codes to maintain quality control standards during production. Cross-reference the datasheet revision date to guarantee alignment with current manufacturing specifications.

Single Diodes Selection Notes

Select this component when a low-profile surface-mount Schottky diode is required for 30 V applications. The SOD-323 package offers a smaller footprint compared to axial leads, suitable for dense PCB layouts. Consider the 200 mA current rating against peak load requirements to prevent thermal overload. Evaluate the 500 nA reverse leakage specification for sensitivity in low-current signal paths. Compare thermal resistance values if operating near the maximum junction temperature limit.

Single Diodes Part Context

This part belongs to the BAT42WS series of Schottky barrier rectifiers from Vishay. The series is characterized by silicon construction and optimized for high-speed switching applications. The WS designation typically indicates a specific surface-mount variant within the broader BAT42 family. These components are widely used in modern electronics requiring reliable rectification with minimal voltage drop.

Single Diodes Replacement Considerations

Publicly confirmed parameter-equivalent substitutes include BAT43WS-E3-08 and BAT43WS-E3-18 from Vishay General Semiconductor. Verify pinout compatibility and thermal performance before substitution. Ensure the alternative part meets the same 30 V reverse voltage and 200 mA current ratings.
