DB151

Bridge Rectifier Overview

The DB151 is a single-phase bridge rectifier manufactured by SMC Diode Solutions. It features a standard silicon construction with a maximum repetitive peak reverse voltage of 50 V and an average forward rectified output current of 1.5 A. The device utilizes the DB-S surface-mount package, characterized as a 4-SMD,鸥翼 (gull-wing) configuration. Electrical specifications include a maximum forward voltage drop of 1.1 V at the rated current and a reverse leakage current of 5 µA at the maximum reverse voltage. The component operates within a junction temperature range of -55°C to 150°C.

Bridge Rectifier Feature Summary

• Glass passivated die construction for enhanced environmental stability
• Low forward voltage drop characteristics for improved efficiency
• High surge current capability suitable for transient loads
• Molded plastic material meeting UL flammability rating 94V-0

Bridge Rectifier Applications

• General purpose AC to DC conversion in low-voltage power supplies
• Battery charging circuits requiring robust reverse blocking
• DC power supply input stages for consumer electronics

Bridge Rectifier Procurement Notes

Verify the specific suffix designation when ordering, as variants such as DB151S indicate surface-mount packaging distinct from through-hole versions. Confirm RoHS compliance status and REACH registration details directly with the manufacturer or authorized distributors prior to procurement. Ensure the selected package matches the intended PCB footprint requirements.

Bridge Rectifier Selection Notes

Select this component for applications requiring a compact surface-mount solution with moderate current handling capabilities. The 50 V rating limits suitability to low-voltage systems; higher voltage ratings are available within the same series for broader input ranges. Evaluate thermal management needs based on the 1.5 A continuous current rating and ambient operating conditions.

Bridge Rectifier Part Context

The DB151 belongs to the DB15x series of single-phase bridge rectifiers produced by SMC Diode Solutions. This series offers various voltage ratings ranging from 50 V to 1000 V while maintaining a consistent 1.5 A current capacity. The DB-S package provides a space-efficient alternative to traditional DIP bridge rectifiers for modern surface-mount assembly processes.

Bridge Rectifier Replacement Considerations

The DBLS151G from Taiwan Semiconductor Corporation is documented as a parameter-equivalent substitute. Verify pinout compatibility and exact electrical tolerances before implementation.
