BAT54T-G

Overview

The BAT54T-G is a single Schottky barrier rectifier manufactured by Taiwan Semiconductor Corporation. It utilizes silicon technology and is housed in an SOT-23 surface-mount package with three terminals. The device supports a maximum continuous forward current of 200 mA and withstands a peak reverse repetitive voltage of 30 V. Key electrical characteristics include a maximum non-repetitive peak forward surge current of 600 mA, a maximum forward voltage of 1 V, and a maximum reverse current of 2 µA. It operates within a temperature range from -65 °C to +125 °C.

Feature Summary

• Utilizes silicon-based Schottky barrier technology for efficient rectification.
• Designed for surface-mount assembly using the compact SOT-23 package.
• Capable of handling high-frequency switching applications due to low capacitance.

Applications

• General-purpose rectification in consumer electronics
• Power supply input protection circuits
• Signal demodulation in RF applications

Procurement Notes

Verify the manufacturer marking on the component body to confirm it reads 'BAT54T' or similar identifiers associated with Taiwan Semiconductor. Ensure the package matches the standard SOT-23 footprint dimensions. Cross-reference the part number suffix '-G' with official distributor catalogs to confirm RoHS compliance status and specific tape-and-reel specifications before finalizing procurement orders.

Selection Notes

Select this component when a single-diode configuration is required rather than dual-series or common-cathode arrangements found in other BAT54 variants. It is suitable for designs needing a balance between low forward voltage drop and robust surge current handling up to 600 mA. Consider the thermal management requirements given the small SOT-23 package size for continuous 200 mA operation.

Part Context

This component belongs to the broader BAT54 family of Schottky diodes produced by various semiconductor manufacturers. While sharing similar electrical ratings such as 30 V reverse voltage and 200 mA forward current, the BAT54T-G specifically denotes the single-diode topology. It differs from configurations like the BAT54S (common cathode) or BAT54AW (dual series), offering a distinct pinout for circuit designers requiring isolated rectification paths.

Replacement Considerations

Compatible substitutes include the BAT54T-TP from Micro Commercial Components and the BAT54T/R from NXP. These alternatives share identical electrical parameters and the SOT-23 package, allowing for direct pin-to-pin replacement in existing designs without circuit modification.

FAQ

What is the difference between the BAT54T-G and the BAT54S?

The BAT54T-G is a single Schottky diode with three pins where two serve as anodes and one as a cathode. In contrast, the BAT54S contains two diodes connected in series with a common cathode, offering different internal connectivity despite similar external packaging.

Is the BAT54T-G suitable for high-frequency switching?

Yes, as a Schottky barrier rectifier, it features fast switching speeds and low reverse recovery time, making it appropriate for high-frequency signal processing and rectification tasks.
