BAT54H RFG

Single Diodes Overview

The BAT54H RFG is a single Schottky barrier diode manufactured by Taiwan Semiconductor. It features a silicon construction housed in an SOT-23-3 surface-mount package. The device supports a maximum repetitive reverse voltage of 30 V and an average forward current of 200 mA. Key electrical parameters include a maximum forward voltage of 800 mV, a peak reverse current of 2 uA, and a power dissipation rating of 200 mW. It operates within a temperature range of -55 C to +125 C and holds AEC-Q101 qualification.

Single Diodes Feature Summary

• Utilizes Schottky barrier technology for low conduction losses and fast switching characteristics.
• Designed for surface-mount applications using the compact SOT-23-3 package.
• Qualified for automotive electronics under the AEC-Q101 standard.

Single Diodes Applications

• Automotive electronic circuits requiring AEC-Q101 compliance
• General-purpose signal rectification in surface-mount designs
• Low-voltage DC-DC converter output stages

Single Diodes Procurement Notes

Verify the specific ordering suffix 'RFG' against the manufacturer's official datasheet to confirm packaging details such as reel size or tape specifications. Ensure the component meets the required AEC-Q101 automotive qualification standards for the intended application environment. Cross-reference the part number with the latest Taiwan Semiconductor documentation to confirm current production status and RoHS compliance before finalizing procurement.

Single Diodes Selection Notes

Select this component when a single Schottky diode configuration is required rather than dual or quad arrangements found in other BAT54 variants. The 30 V reverse voltage rating suits low-voltage systems, while the 200 mA current capacity supports moderate load requirements. Consider the SOT-23-3 footprint constraints and the specific thermal management needs associated with the 200 mW power dissipation limit during circuit design.

Single Diodes Part Context

This component belongs to the BAT54 series of Schottky barrier diodes, which are widely used for their low forward voltage drop and high-speed switching capabilities. The BAT54H variant specifically denotes a single-diode configuration, distinguishing it from dual (BAT54S) or quad (BAT54) versions within the same family. Manufactured by Taiwan Semiconductor, it targets applications demanding reliable performance in compact surface-mount layouts.

Single Diodes Replacement Considerations

Publicly confirmed substitute part numbers for this specific component were not identified in the provided source material. Verify compatibility with alternative single Schottky diodes by matching the SOT-23-3 package, 30 V reverse voltage, and 200 mA forward current ratings.
