BAT54DF

Overview

The BAT54DF is a surface mount Schottky barrier diode array manufactured by SMC Diode Solutions. It features two independent diodes housed in a compact 6-UDFN package, specifically the DFN2015-6L configuration. The device is rated for a maximum reverse voltage of 30 V and an average forward current of 100 mA. Designed for high-speed applications, it offers low conduction losses and negligible switching losses due to its Schottky barrier construction. The component complies with ECOPACK 2 environmental standards, ensuring lead-free assembly and halogen-free materials suitable for modern electronics manufacturing requirements.

Feature Summary

• Dual independent Schottky barrier diode configuration within a single surface mount package
• Extremely fast switching characteristics with low forward and reverse recovery times
• Low capacitance design minimizing signal distortion in high-frequency circuits
• ECOPACK 2 compliant construction supporting environmentally friendly assembly processes

Applications

• High-speed switching power supply rectification
• Signal detection and demodulation circuits
• Protection against reverse polarity in portable devices
• Clamping applications in RF and microwave systems

Procurement Notes

Verify the specific package marking and tape & reel specifications when sourcing from distributors. Confirm that the received components match the DFN2015-6L footprint dimensions. Ensure compliance with RoHS and REACH directives as indicated by the ECOPACK 2 designation. Cross-reference the manufacturer part number BAT54DF with authorized SMC Diode Solutions channels to avoid counterfeit products. Check datasheet revisions for any updates to thermal or electrical ratings prior to final procurement.

Selection Notes

Select this component when space constraints require a dual-diode solution in a small outline package. The 30 V rating suits low-voltage logic and battery-powered applications. Consider the 100 mA current limit for load requirements. The independent configuration allows flexible circuit topologies compared to common cathode variants. Evaluate thermal dissipation capabilities based on the PCB copper area available for heat spreading.

Part Context

This part belongs to the broader BAT54 series of general-purpose signal Schottky diodes. While the standard BAT54 is often found in SOT-23 or SOD packages, the BAT54DF variant specifically utilizes the 6-UDFN form factor. This distinction is critical for PCB layout compatibility. The series is characterized by low forward voltage drop and fast recovery times, making it suitable for replacing older PIN diode technologies in efficiency-critical designs.

Replacement Considerations

Direct substitutes include other manufacturers' BAT54DF equivalents in the 6-UDFN package. Verify pinout compatibility and electrical parameters such as reverse voltage and forward current before substitution. Generic BAT54 replacements may differ in package type and must be evaluated for mechanical fit.
