BAT54 RFG

Single Diodes Overview

The BAT54SH RFG is a dual Schottky barrier diode manufactured by Taiwan Semiconductor Corporation, housed in an SOT-23-3 surface-mount package. It features a silicon construction with a maximum repetitive reverse voltage of 30 V and an average forward current of 200 mA per diode. The device exhibits a low forward voltage drop of 800 mV at 100 mA and a maximum reverse leakage current of 2 µA. Designed for high-speed switching applications, it operates within a junction temperature range of -55 °C to +125 °C and holds AEC-Q101 automotive qualification.

Single Diodes Feature Summary

• Dual common cathode configuration for efficient signal clamping and protection
• Low forward voltage drop minimizes power loss in high-speed switching circuits
• Automotive-grade reliability certified under AEC-Q101 standards
• Compact SOT-23-3 footprint suitable for dense surface-mount layouts

Single Diodes Applications

• JTAG interface protection against electrostatic discharge and surge events
• High-frequency rectification in consumer electronics
• Signal clamping in portable devices and communication equipment

Single Diodes Procurement Notes

Verify the specific suffix 'RFG' corresponds to the required tape-and-reel packaging format during sourcing. Confirm that the component meets RoHS directives if environmental compliance is mandatory for the assembly process. Ensure the supplier provides traceability documentation consistent with automotive quality requirements given the AEC-Q101 certification status of this series.

Single Diodes Selection Notes

Select this component when a dual Schottky diode with low capacitance and fast recovery characteristics is required for signal integrity preservation. The 30 V rating suits low-voltage logic interfaces, while the 200 mA current capability supports moderate load conditions. Consider the thermal dissipation limits of the SOT-23 package for high-density PCB designs where heat accumulation may affect performance.

Single Diodes Part Context

This part belongs to the BAT54 family of Schottky barrier diodes from Taiwan Semiconductor, which includes variants like BAT54S, BAT54AW, and BAT54CW. These components share similar electrical profiles but differ in forward voltage specifications and packaging options. The BAT54SH variant specifically denotes the dual common cathode configuration optimized for bidirectional protection schemes.

Single Diodes Replacement Considerations

Direct substitutes include BAT54S RFG and BAT54SW RFG from the same manufacturer, provided pin compatibility and electrical ratings align with the design requirements.
