BAT42WS-G3-18

Single Diodes Overview

The BAT42WS-G3-18 is a Schottky barrier rectifier manufactured by Vishay General Semiconductor - Diodes Division. It features a maximum repetitive reverse voltage of 30 V and an average forward rectified current of 200 mA. The device utilizes the SOD-323 (SC-76) surface-mount package. Key electrical specifications include a maximum reverse leakage current of 500 nA at 25 V, a typical junction capacitance of 7 pF at 1 V and 1 MHz, and a fast reverse recovery time of 5 ns.

Single Diodes Feature Summary

• Schottky technology for low forward voltage drop and high switching efficiency
• Plastic encapsulation utilizing molded compound meeting UL flammability classification 94V-0
• Designed for surface-mount applications with a compact SOD-323 footprint

Single Diodes Applications

• High-frequency rectification in DC-DC converters
• Clamping and protection circuits in RF and IF stages
• Free-wheeling diodes in low-voltage power supply designs

Single Diodes Procurement Notes

Verify the complete part number including the suffix to confirm the specific tape-and-reel packaging configuration intended for automated assembly. Confirm RoHS compliance status through the official datasheet or manufacturer documentation prior to integration into environmentally regulated assemblies. Ensure the ordering quantity aligns with standard reel sizes to avoid cut-tape premiums if not required.

Single Diodes Selection Notes

Select this component when a low-profile surface-mount Schottky diode is required for 30 V reverse voltage applications. The SOD-323 package offers space savings compared to axial leads. Consider the 200 mA current rating and 5 ns recovery time for suitability in high-speed switching environments where minimal reverse recovery charge is critical for system performance.

Single Diodes Part Context

This device belongs to the BAT42WS series of small-signal Schottky diodes. The 'G3' suffix indicates lead-free construction and halogen-free molding compound. The '-18' suffix typically denotes the specific reel packaging format provided by the distributor. These components are part of Vishay's portfolio of general-purpose signal diodes designed for consumer electronics and telecommunications equipment.

Single Diodes Replacement Considerations

Direct pin-compatible replacements within the same family include BAT43WS-G3-18, which shares the SOD-323 package but may differ in specific thermal or mechanical tolerances. Verify that substitute parts maintain the 30 V reverse voltage and 200 mA forward current ratings to ensure circuit integrity without redesign.
