BAT46GW

Single Diodes Overview

The BAT46GW is a single Schottky barrier diode manufactured by Taiwan Semiconductor Corporation. It features a maximum repetitive peak reverse voltage of 100 V and an average forward rectified current of 250 mA DC. The device utilizes the SOD-123 surface-mount package. Key electrical characteristics include a maximum forward voltage of 1 V at 250 mA and a low leakage current of 9 µA at 100 V. The junction temperature rating reaches a maximum of 150 °C, ensuring reliable operation in standard electronic circuits.

Single Diodes Feature Summary

• High breakdown voltage capability for robust reverse bias performance
• Low forward voltage drop to minimize power loss during conduction
• Surface-mounted design in a compact SOD-123 package for automated assembly

Single Diodes Applications

• General purpose rectification in consumer electronics
• Power supply input protection circuits
• Freewheeling diodes in low-current switching applications

Single Diodes Procurement Notes

Verify the manufacturer marking on the component body to confirm Taiwan Semiconductor origin, as identical part numbers exist from other vendors like Nexperia. Ensure the ordering suffix matches the specific tape-and-reel or cut-tape requirements for your production line. Cross-reference the datasheet revision date to ensure compatibility with your design specifications before finalizing procurement orders.

Single Diodes Selection Notes

Select this component when a small form factor Schottky diode is required for 100 V blocking applications. The SOD-123 package offers a balance between thermal performance and board space efficiency. Consider the 250 mA current limit when designing for continuous load conditions. Verify that the 1 V forward voltage meets the system's efficiency targets compared to lower-voltage alternatives.

Single Diodes Part Context

This component belongs to the family of planar Schottky barrier diodes designed for high-speed switching and low-loss rectification. The SOD-123 package is widely used in portable devices due to its small footprint. Similar parts in this category often feature integrated guard rings for stress protection, enhancing reliability under transient voltage conditions common in modern electronic systems.

Single Diodes Replacement Considerations

The BAT46WH,115 from Nexperia is a confirmed substitute with identical 100 V, 250 mA ratings and SOD-123 packaging. Verify pinout compatibility and thermal characteristics before substitution. Other generic equivalents may exist but require careful validation of reverse leakage and forward voltage parameters against the original specification.
