DB101S

Bridge Rectifier Overview

The DB101S is a single-phase bridge rectifier manufactured by SMC Diode Solutions, designed for surface-mount applications. It features a maximum average forward rectified current of 1 A and a peak repetitive reverse voltage rating of 50 V. The device utilizes standard silicon technology and is housed in a compact 4-SMD,鸥翼 (gull-wing) package, specifically identified as the DB-S supplier device package. Electrical characteristics include a maximum forward voltage drop of 1.1 V at 1 A and a reverse leakage current of 5 µA at 50 V. The component operates within a junction temperature range of -55°C to 150°C and complies with RoHS3 standards.

Bridge Rectifier Feature Summary

• Surface-mount construction in a compact DB-S package suitable for automated assembly
• Standard silicon bridge rectifier configuration for general-purpose power conversion
• High thermal stability with an extended operating junction temperature range

Bridge Rectifier Applications

• General-purpose AC to DC rectification in low-power consumer electronics
• Power supply input stages for devices requiring surface-mount integration
• Battery charging circuits with limited space constraints

Bridge Rectifier Procurement Notes

Verify the specific suffix against the manufacturer's datasheet to confirm pinout orientation and packaging type, as variations exist within the DB series. Ensure the selected variant matches the required voltage rating of 50 V for the intended circuit design. Cross-reference the official SMC Diode Solutions documentation to validate compliance with current environmental regulations and material specifications before finalizing procurement orders.

Bridge Rectifier Selection Notes

Select the DB101S when a 50 V reverse voltage rating and 1 A current capacity are sufficient for the application. Consider this component for designs prioritizing board space efficiency due to its surface-mount footprint. Evaluate thermal management requirements based on the 150°C junction temperature limit and ensure the PCB layout supports the heat dissipation needs of a standard silicon bridge rectifier in the specified package.

Bridge Rectifier Part Context

The DB101S belongs to the DB series of single-phase bridge rectifiers from SMC Diode Solutions, which offers various voltage ratings within the same physical footprint family. This specific model provides the lowest voltage option (50 V) in the standard DB-S surface-mount lineup, complementing higher voltage variants like the DB107S. The series is engineered for cost-effective, high-volume manufacturing in compact electronic devices where traditional through-hole rectifiers would consume excessive board area.
