Bridge Rectifier datasheet and documents for DB104ST-HF

DB104ST-HF

Bridge Rectifier Overview

The DB104ST-HF is a surface-mount glass passivated single-phase bridge rectifier manufactured by Comchip Technology. It features a maximum average forward rectified current of 1.0 A and a peak repetitive reverse voltage rating of 400 V. The device exhibits a maximum forward voltage drop of 1.1 V at 1.0 A DC and a maximum RMS voltage of 280 V. It supports a peak forward surge current of 200 A under JEDEC testing conditions. The component operates within a junction temperature range of -55°C to +150°C and includes a typical thermal resistance of 40°C/W.

Bridge Rectifier Feature Summary

Glass passivated chip junction for enhanced reliability
Low forward voltage drop for improved efficiency
High current capability suitable for PCB mounting

Bridge Rectifier Applications

Printed circuit board assembly in power supply units
General purpose rectification in electronic circuits
AC to DC conversion stages

Bridge Rectifier Procurement Notes

Verify the specific ordering suffix 'ST' corresponds to reel packaging rather than tube configuration, as indicated in the manufacturer's standard packaging table. Confirm RoHS compliance status and ensure the component matches the DBS case type dimensions for proper footprint compatibility during procurement.

Bridge Rectifier Selection Notes

Select this component when a 400V reverse voltage rating and 1.0A continuous current are required in a surface-mount form factor. Ensure the application environment stays within the specified -55°C to +150°C operating temperature range and consider derating guidelines for capacitive loads if applicable.

Bridge Rectifier Part Context

This part belongs to the DB101S through DB107S series of SMD glass passivated bridge rectifiers. The series offers varying reverse voltage ratings from 50V to 1000V while maintaining a consistent 1.0A forward current capability. The DB104ST-HF specifically provides the 400V variant in reel packaging.

Bridge Rectifier Replacement Considerations

Compatible substitutes include other 400V, 1A SMD bridge rectifiers in the DBS package, such as the DB104-G or equivalent parts from other manufacturers utilizing the same footprint and electrical specifications.
