LSM545JE3

Single Diodes Overview

The LSM545JE3 is a Schottky barrier rectifier manufactured by Microsemi Corporation, housed in the DO-214AB (SMC) surface-mount package. It features a maximum DC reverse voltage of 45 V and an average forward rectified current rating of 5 A. The device exhibits a low forward voltage drop of 600 mV at 5 A and a maximum reverse leakage current of 1.5 mA at 45 V. Operating within a junction temperature range of -55°C to 150°C, it is designed for high-efficiency power conversion applications requiring fast switching characteristics.

Single Diodes Feature Summary

• Schottky barrier technology ensures low forward voltage drop and minimal power loss for high efficiency.
• Guard ring structure provides enhanced reverse protection and robustness against transient conditions.
• Surface-mount DO-214AB packaging facilitates automated assembly and compact board layout.

Single Diodes Applications

• High-frequency DC-DC converters
• Free-wheeling diodes in synchronous rectification circuits
• Power supply input rectification

Single Diodes Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and specific lot traceability upon receipt. Note that availability may be limited as distribution statuses can change; validate current stock levels with suppliers before finalizing procurement plans.

Single Diodes Selection Notes

Select this component for applications requiring low forward voltage to minimize conduction losses at high currents. Ensure the operating environment stays within the specified -55°C to 150°C junction temperature range. Verify that the peak repetitive reverse voltage does not exceed 45 V under all transient conditions.

Single Diodes Part Context

This part belongs to the LSM series of Schottky rectifiers from Microsemi, designed for general-purpose power management. It complements other variants in the family offering different current ratings or voltage thresholds, providing designers with options for optimizing efficiency and size in various power stages.

Single Diodes Replacement Considerations

Direct substitutes include LSM345JE3 (3A rating) if current requirements allow reduction. Cross-reference with equivalent SMC-packaged Schottky diodes from other manufacturers ensuring matching 45V Vr and 5A Io specifications.
