BAT54KFILM

Single Diodes Overview

The BAT54KFILM is a surface-mount Schottky barrier diode from STMicroelectronics, housed in a compact SOD-523 package. It features a peak reverse repetitive voltage (Vrrm) of 40 V and a maximum continuous forward current (If) of 300 mA. The device exhibits a low forward voltage (Vf) of 900 mV at rated current and a peak reverse recovery time (trr) of 5 ns. Operating temperature ranges from -40°C to +150°C junction temperature, with a non-repetitive peak forward surge current (Ifsm) of 1 A and a reverse leakage current (Ir) of 1 μA.

Single Diodes Feature Summary

• Utilizes Schottky barrier technology for negligible switching losses and extremely fast switching speeds.
• Designed as a low capacitance diode suitable for high-frequency signal applications.
• Compliant with ECOPACK 2 environmental standards.

Single Diodes Applications

• General purpose signal rectification
• High-speed switching circuits
• Low voltage power management

Single Diodes Procurement Notes

Verify the specific suffix 'K' against the official STMicroelectronics datasheet to confirm exact binning or tape-and-reel specifications. Ensure the ordering part number matches the required packaging format. Cross-reference the component marking code on the physical device with manufacturer documentation to prevent counterfeit substitution.

Single Diodes Selection Notes

Select this component when a single Schottky diode with 40 V reverse voltage capability is required in an SOD-523 footprint. It is appropriate for designs prioritizing low forward voltage drop and minimal reverse recovery charge over higher current handling capacities found in larger packages.

Single Diodes Part Context

This component belongs to the BAT54 series of general-purpose signal Schottky diodes. The series offers various package options including SO123, SOD323, SOD523, SOT-23, and SOT-323. The BAT54KFILM specifically utilizes the SOD-523 surface mount package, providing a small form factor for space-constrained PCB layouts.

Single Diodes Replacement Considerations

Direct replacements within the same family include BAT54FILM and BAT54JFILM. Verify pinout compatibility and electrical parameter tolerances before substituting.
