BAT54CWF

Overview

The BAT54CWF is a silicon Schottky barrier diode manufactured by Nexperia, housed in an SOT-323 (SC-70) surface-mount package. It features a dual anode common cathode configuration with three terminals. Key electrical parameters include a maximum repetitive reverse voltage of 25 V and a continuous forward current rating of 100 mA. The device exhibits a typical forward voltage of 800 mV at 100 mA and a maximum reverse leakage current of 2 µA. It supports a non-repetitive peak forward surge current of 600 mA and operates within a junction temperature range of -65 °C to +150 °C.

Feature Summary

• Dual anode common cathode configuration for flexible circuit integration
• Ultra-fast switching characteristics suitable for high-frequency applications
• Guard ring protected structure for enhanced stress resilience
• Low forward voltage drop and minimal power switching losses

Applications

• Voltage clamping in signal processing circuits
• Protection against reverse polarity in portable devices
• Blocking diodes in low-voltage power paths
• Line termination in high-speed digital interfaces

Procurement Notes

Verify the specific suffix 'WF' corresponds to the SOT-323 tape-and-reel packaging format required for your assembly line. Confirm RoHS compliance status through the official datasheet before finalizing procurement. Ensure design-in approval accounts for the component's thermal dissipation limits within the small outline package constraints.

Selection Notes

Select this component when a compact dual-anode Schottky solution is needed with a 25 V reverse voltage rating. The SOT-323 package offers space efficiency compared to larger footprints. Consider the 100 mA current limit for load requirements. Verify that the 800 mV forward voltage aligns with system efficiency targets compared to lower-drop alternatives.

Part Context

This part belongs to the BAT54 series of Schottky diodes from Nexperia, designed for general-purpose switching and protection. The series includes variants with different packages and configurations, such as the BAT54C in SOT-23 or BAT54CV in SOT-666. The BAT54CWF specifically utilizes the SC-70 form factor, distinguishing it from other series members by its physical dimensions and pinout compatibility.

Replacement Considerations

Direct substitutes include BAT54CW from NXP Semiconductors, which shares identical electrical specifications and the SOT-323 package. Other compatible options within the same family may require verification of pinout compatibility and exact forward voltage tolerances to ensure seamless integration without circuit redesign.
