BAT54SWF

Overview

The BAT54SWF is a dual Schottky barrier rectifier manufactured by Nexperia USA Inc. It utilizes silicon technology and is housed in an SOT-323 (SC-70) surface-mount package with three terminals. The device features a common cathode configuration, integrating two independent diodes within a single compact footprint. Key electrical specifications include a maximum repetitive peak reverse voltage of 30 V and a continuous forward current rating of 200 mA. The component supports a maximum forward voltage of 800 mV at the rated current and exhibits a low reverse leakage current of 2 µA. It operates reliably across a temperature range from -65 °C to +125 °C.

Feature Summary

• Dual Schottky barrier rectifier design for efficient signal detection and power management
• Common cathode configuration allowing flexible circuit integration
• Ultra-small SOT-323 surface-mount package for space-constrained applications

Applications

• Signal detection in communication equipment
• Power management circuits in portable devices
• Clamping and protection in high-speed data lines

Procurement Notes

Verify the specific suffix 'F' against official Nexperia documentation to confirm tape-and-reel packaging details, as standard listings may default to cut-tape or reel formats without explicit confirmation. Ensure the ordering code matches the exact pinout and marking requirements for your assembly process. Cross-reference the datasheet revision date to guarantee compliance with current RoHS directives and material declarations before finalizing procurement orders.

Selection Notes

Select this component when a dual Schottky diode with a common cathode topology is required in a minimal footprint. The SOT-323 package offers a balance between thermal performance and board space efficiency compared to larger through-hole alternatives. Consider the 30 V reverse voltage rating and 200 mA current capacity to ensure adequate headroom for the intended application's peak operating conditions and transient loads.

Part Context

This part belongs to the Nexperia BAT54 series of small-signal Schottky diodes. The series is widely recognized for its fast switching characteristics and low forward voltage drop. The BAT54SW variant specifically denotes the dual common cathode configuration in the SOT-323 package, distinguishing it from other configurations like the BAT54S (dual common anode) or BAT54A (single diode).

Replacement Considerations

Compatible substitutes include the BAT54S,115 for dual common cathode applications in similar packages, and the BAT54A,115 for single diode needs. Verify pin compatibility and electrical ratings against the original specification sheet before substitution.
