BAT5403WE6327HTSA1

Single Diodes Overview

The BAT5403WE6327HTSA1 is a silicon Schottky diode manufactured by Infineon Technologies, housed in a PG-SOT323 surface-mount package. It features a dual common-cathode configuration with two independent diodes within a single compact footprint. The device supports a maximum repetitive peak reverse voltage of 4V and a continuous forward current of 110mA. Power dissipation is rated at 100mW, with a junction temperature range extending up to 150°C. Capacitance is specified at 0.35pF at 0V and 1MHz, ensuring minimal signal interference in high-frequency applications.

Single Diodes Feature Summary

• Dual common-cathode Schottky topology for efficient space-saving integration
• Ultra-low junction capacitance suitable for high-speed switching and RF environments
• Compact PG-SOT323 surface-mount packaging for automated assembly

Single Diodes Applications

• High-speed switching circuits
• RF signal processing
• Clamping and protection in low-voltage digital interfaces

Single Diodes Procurement Notes

Verify the specific suffix HTSA1 against official Infineon documentation to confirm tape-and-reel packaging specifications. Ensure compatibility with PG-SOT323 footprints during PCB layout. Confirm that the 4V reverse voltage rating aligns with circuit requirements, as this is a low-voltage component unsuitable for higher voltage blocking applications.

Single Diodes Selection Notes

Select this component when low forward voltage drop and minimal capacitance are critical for signal integrity. The dual common-cathode arrangement simplifies design compared to discrete single diodes. Verify thermal management capabilities, as the small SOT-323 package has limited power dissipation capacity relative to larger packages.

Single Diodes Part Context

This part belongs to Infineon's BAT54 series of small-signal Schottky diodes. The WE6327HTSA1 suffix indicates specific manufacturing and packaging details defined by Infineon. It is designed for consumer electronics and industrial applications requiring fast recovery times and low leakage currents in compact form factors.

Single Diodes Replacement Considerations

Check for direct pin-compatible alternatives such as BAT54S or BAT54A from other manufacturers, ensuring voltage and current ratings meet or exceed the original specifications. Verify package dimensions and electrical characteristics before substitution.
