DB155S

Bridge Rectifier Overview

The DB155S is a single-phase standard bridge rectifier manufactured by SMC Diode Solutions. It features a maximum repetitive peak reverse voltage of 600 V and an average rectified output current of 1.5 A. The device utilizes a surface-mount DB-S package, specifically a 4-SMD鸥翼 (gull-wing) configuration. Electrical characteristics include a forward voltage drop of 1.1 V at the rated current and a reverse leakage current of 5 µA at 600 V. The component operates within a junction temperature range of -55°C to 150°C and complies with RoHS3 standards.

Bridge Rectifier Feature Summary

Bridge Rectifier Procurement Notes

Verify the manufacturer part number DB155S against official SMC Diode Solutions documentation to confirm electrical specifications and package integrity. Ensure compliance with project requirements regarding RoHS3 status and moisture sensitivity level MSL classification before integration into production workflows.

Bridge Rectifier Selection Notes

Select this component when a 600 V reverse voltage rating and 1.5 A continuous current capacity are required in a surface-mount form factor. Compare the 1.1 V forward voltage drop against alternative bridge rectifiers to evaluate conduction losses. Confirm that the 4-SMD gull-wing footprint matches the target PCB layout constraints.

Bridge Rectifier Part Context

This component belongs to the DB15x series of single-phase bridge rectifiers from SMC Diode Solutions. The series differentiates parts primarily by their peak reverse voltage ratings while maintaining consistent current handling and physical packaging dimensions across variants.
