BAT54

Single Diodes Overview

The BAT54 is a silicon Schottky barrier signal diode manufactured by Taiwan Semiconductor Corporation. It features a single diode element housed in a surface-mount SOT-23 package with three terminals. The device is rated for a maximum repetitive peak reverse voltage of 30 V and an average forward rectified current of 0.2 A. Key electrical characteristics include a maximum non-repetitive peak forward surge current of 0.6 A and a maximum power dissipation of 0.225 W. The component operates within a storage temperature range typically spanning from -55 °C to +150 °C, ensuring reliability in standard electronic applications.

Single Diodes Feature Summary

• Utilizes Schottky barrier technology for extremely fast switching speeds

Single Diodes Procurement Notes

Verify the specific manufacturer datasheet for the Taiwan Semiconductor variant, as pinout configurations and exact thermal ratings may differ between suppliers. Confirm RoHS compliance status and ensure the ordering part number matches the required tape-and-reel or cut-tape packaging format for your assembly line.

Single Diodes Selection Notes

Select this component when a low-capacitance, high-speed switching diode is required in a small form factor. Ensure the circuit design accounts for the 30 V reverse voltage limit and 0.2 A continuous current rating. Verify that the SOT-23 footprint aligns with the PCB layout constraints and that the operating temperature range meets environmental requirements.

Single Diodes Part Context

This component belongs to the broader BAT54 family of Schottky diodes, which includes various configurations such as common cathode pairs and arrays. While the core technology remains consistent across manufacturers, physical dimensions and specific electrical tolerances can vary. This specific entry refers to the single-diode version provided by Taiwan Semiconductor Corporation.

Single Diodes Replacement Considerations

Compatible substitutes include BAT54 variants from other manufacturers like Nexperia or Diodes Incorporated, provided they share the same SOT-23 package and electrical specifications. Always verify pin compatibility and thermal performance before substitution.
