BAT54W

Single Diodes Overview

The BAT54W is a single-element silicon Schottky barrier signal diode manufactured by SMC Diode Solutions. It is housed in an ultra-small SOT-323 surface-mount package. The device supports a maximum average forward current of 0.2 A and a repetitive peak reverse voltage of 30 V. Key electrical characteristics include a low forward voltage drop, typically 0.5 V at 0.03 A, and a maximum non-repetitive peak forward surge current of 0.6 A. The component is designed for general-purpose applications requiring fast switching and low conduction losses.

Single Diodes Feature Summary

• Utilizes planar Schottky barrier technology for low forward voltage and negligible switching losses
• Encapsulated in a compact SOT-323 plastic surface-mount package for space-constrained designs
• Constructed with silicon material for reliable signal rectification

Single Diodes Applications

• General purpose signal rectification
• Clamping and protection circuits
• Low voltage power management

Single Diodes Procurement Notes

Verify the specific manufacturer designation when sourcing, as the BAT54W part number is utilized by multiple semiconductor producers including STMicroelectronics, Diodes Inc., and Nexperia. Confirm that the supplier is SMC Diode Solutions if that specific origin is required for your bill of materials. Ensure the datasheet matches the exact electrical parameters and package dimensions listed above before finalizing procurement.

Single Diodes Selection Notes

Select this component for applications requiring a single Schottky diode in a minimal footprint. It is suitable where low forward voltage and fast recovery are prioritized over high current handling. Compare against dual-diode variants like the BAT54C or BAT54S if circuit topology requires common cathode or common anode configurations instead of a single isolated element.

Single Diodes Part Context

This component belongs to the broader BAT54 family of small-signal Schottky diodes. While the base BAT54 designation often refers to dual-diode configurations (such as common cathode or common anode), the BAT54W specifically denotes a single-diode variant within the same series. It shares the same SOT-323 packaging and fundamental silicon Schottky technology as its multi-element counterparts.

Single Diodes Replacement Considerations

Direct functional substitutes include other single-element Schottky diodes in the SOT-323 package with similar 30V/0.2A ratings, such as the BAT54W from Diodes Inc. or Nexperia. Verify pinout compatibility and thermal characteristics when replacing with parts from different manufacturers.
