BAT54LT3G

Single Diodes Overview

The BAT54LT3G is a dual Schottky barrier rectifier manufactured by onsemi, housed in a surface-mount SOT-23 package. It features a common cathode configuration with two independent diodes sharing a single cathode terminal. The device supports a maximum repetitive reverse voltage of 30 V and a continuous forward current of 200 mA. Key electrical characteristics include a low forward voltage drop of 800 mV at rated current, a peak non-repetitive forward surge current capability of 600 mA, and a maximum reverse leakage current of 2 µA. The component operates within a temperature range of -55 °C to +125 °C.

Single Diodes Procurement Notes

Verify the specific suffix 'T3G' against official onsemi documentation to confirm the tape-and-reel packaging format and lead-free status. Ensure the ordering part number matches the required automotive or industrial grade specifications if applicable. Cross-reference the datasheet revision date to validate the technical parameters provided in procurement catalogs.

Single Diodes Selection Notes

Select this component when a dual Schottky diode with a common cathode topology is required in a compact SOT-23 form factor. It is appropriate for designs prioritizing low forward voltage drop and fast switching speeds over high current handling capabilities. Consider thermal dissipation limits and ambient operating temperatures when integrating into dense PCB layouts.

Single Diodes Part Context

This component belongs to the BAT54 series of small-signal Schottky diodes from onsemi. The series offers various configurations including common anode and common cathode variants in SOT-23 packages. These devices are engineered for general-purpose rectification and switching applications where space constraints and low power consumption are critical design factors.

Single Diodes Replacement Considerations

Compatible substitutes include BAT54S, BAT54AW, and BAT54AL from onsemi, which share similar electrical ratings but may differ in forward voltage characteristics or pinout configurations. Verify pin compatibility and thermal performance before substituting.
