BAT54AWFILMY

Overview

The BAT54AWFILMY is a dual Schottky barrier diode array manufactured by STMicroelectronics, housed in an SOT-323 surface-mount package. It features a common anode configuration with two independent elements. The device supports a maximum repetitive reverse voltage of 40 V and a continuous forward current of 300 mA per diode. Key electrical characteristics include a low forward voltage of 900 mV at 100 mA, a peak reverse recovery time of 5 ns, and a reverse leakage current of 1 µA at 30 V. It operates within a junction temperature range of -40 °C to +150 °C.

Feature Summary

• Dual Schottky barrier diodes integrated into a single compact surface-mount package
• Common anode configuration for efficient circuit design
• Extremely fast switching speeds with negligible reverse recovery time
• Low forward voltage drop to minimize conduction losses

Applications

• High-speed signal rectification in consumer electronics
• Clamping and protection circuits for sensitive inputs
• DC-DC converter freewheeling applications
• Logic level translation and OR-ing functions

Procurement Notes

Verify the specific suffix 'Y' against official manufacturer documentation to confirm tape-and-reel packaging specifications or any minor parameter deviations from the standard BAT54AWFILM variant. Ensure compliance with RoHS directives and check for end-of-life notices or production change notifications prior to finalizing procurement plans.

Selection Notes

Select this component when a common anode dual Schottky configuration is required in space-constrained designs. The SOT-323 package offers a smaller footprint compared to SOT-23 alternatives. Consider the 40 V rating and 300 mA current capacity to ensure adequate headroom for the target application's voltage and current requirements.

Part Context

This part belongs to the BAT54 series of general-purpose small-signal Schottky diodes from STMicroelectronics. The series utilizes silicon technology to provide low conduction and reverse losses. It is designed for high-efficiency applications requiring fast switching capabilities in a miniature surface-mount form factor suitable for automated assembly processes.

Replacement Considerations

BAT54AWFILM is the base equivalent without the reel suffix. BAT54CFILM provides a common cathode configuration instead of common anode.
