BAT42WS-HE3-18

Single Diodes Overview

The BAT42WS-HE3-18 is a single Schottky barrier rectifier manufactured by Vishay General Semiconductor - Diodes Division. It utilizes metal-to-silicon construction to provide low forward voltage drop and fast switching characteristics. The device is housed in the SOD-323 surface-mount package, designed for high-volume automated assembly. It features an integrated electrostatic discharge (ESD) protection mechanism to safeguard against excessive voltage events. The component operates within a junction temperature range of up to 150°C and complies with RoHS directives.

Single Diodes Feature Summary

• Low forward voltage drop for improved efficiency
• Fast switching capability for high-speed applications
• Integrated ESD protection circuitry
• Lead-free finish compliant with environmental standards

Single Diodes Applications

• DC-DC converter circuits
• Power supply rectification
• Protection diodes in electronic systems

Single Diodes Procurement Notes

Verify the specific suffix HE3-18 to confirm lead-free plating and tape-and-reel packaging configuration. Ensure the ordering part number matches the required SOD-323 footprint and electrical ratings for your design. Cross-reference the manufacturer datasheet for absolute maximum ratings before finalizing procurement specifications.

Single Diodes Selection Notes

Select this component when a small surface-mount Schottky diode with integrated ESD protection is required. The SOD-323 package offers space savings compared to axial leads. Verify that the 30V reverse voltage and 200mA average current ratings align with the circuit's peak operating conditions and thermal management capabilities.

Single Diodes Part Context

This part belongs to the BAT4x series of general-purpose Schottky diodes from Vishay. The series is characterized by its metal-to-silicon technology, which ensures low leakage current and high reliability. The WS variant indicates the specific SMD casing style, while the HE3 designation confirms the halogen-free and lead-free material composition.

Single Diodes Replacement Considerations

Direct substitutes include BAT42W-E3-18 or BAT42WS-G3-18 from Vishay, which share identical electrical parameters and mechanical dimensions. Other manufacturers offering SOD-323 Schottky diodes with similar 30V/200mA ratings may be considered if pin compatibility and thermal performance are verified.
