BAT54SW

Overview

The BAT54SW is a dual Schottky barrier diode array manufactured by SMC Diode Solutions, housed in an SOT-523 surface-mount package. It features a common cathode configuration with two independent silicon elements. The device supports a maximum repetitive reverse voltage of 30 V and an average forward rectified current of 100 mA per diode. Key electrical characteristics include a low forward voltage drop of 1 V at 100 mA and a rapid reverse recovery time of 5 ns. Operating junction temperatures range up to 125°C, ensuring reliability in compact electronic designs requiring fast switching and low conduction losses.

Feature Summary

• Dual Schottky barrier diodes integrated into a single compact surface-mount package
• Common cathode configuration for efficient circuit layout
• Ultra-fast switching performance with minimal reverse recovery time
• Low forward voltage drop to reduce power dissipation

Applications

• High-speed signal switching and logic level shifting
• DC-DC converter freewheeling and clamping circuits
• RF mixer and detector applications
• Automotive electronics protection circuits

Procurement Notes

Verify the specific manufacturer designation on the component marking, as the BAT54SW part number may be utilized by multiple semiconductor producers including SMC Diode Solutions and others. Confirm that the received components match the exact SOT-523 package dimensions and pinout configuration required by your design. Ensure compliance with relevant environmental standards such as RoHS if specified for your project requirements before final integration.

Selection Notes

Select this component when a small form factor is critical due to its SOT-523 packaging. It is suitable for applications demanding fast switching speeds and low forward voltage drops. Consider the 100 mA current rating per diode when designing power paths. Verify thermal management needs based on the 125°C maximum junction temperature limit and ensure the reverse voltage rating of 30 V exceeds the peak inverse voltage in the target circuit.

Part Context

This component belongs to the broader BAT54 series of dual Schottky diodes, which are widely used in consumer electronics and automotive systems. The series typically includes variants like BAT54A, BAT54C, and BAT54S, differing primarily in internal configurations or slight parameter variations. The BAT54SW specifically denotes the SMC Diode Solutions version in the SOT-523 package, distinguishing it from other manufacturers' offerings or alternative package types like SOT-23.

Replacement Considerations

Direct substitutes include BAT54A, BAT54C, and BAT54S from various manufacturers, provided they share the same SOT-523 package and common cathode configuration. Verify that replacement parts meet the 30 V reverse voltage and 100 mA current specifications. Cross-reference datasheets to ensure compatibility in switching speed and forward voltage characteristics for seamless integration.
