DB103S

Bridge Rectifier Overview

The Rectron DB103S is a single-phase glass passivated silicon bridge rectifier designed for surface mount applications. It features a maximum average forward output current of 1.0 A and a maximum repetitive peak reverse voltage of 200 V. The device exhibits a maximum forward voltage drop of 1.0 V at 1.0 A DC and a maximum reverse current of 5 uA at rated voltage. It supports a peak forward surge current of 30 A under JEDEC testing conditions. Operating temperatures range from -55°C to +150°C, with thermal resistance values of 40°C/W junction-to-ambient and 15°C/W junction-to-lead.

Bridge Rectifier Feature Summary

• Glass passivated construction ensures reliable performance and stability under various electrical loads.
• Molded polarity symbols on the body facilitate correct orientation during automated assembly processes.
• UL flammability classification 94V-0 epoxy provides safety compliance for printed circuit board integration.

Bridge Rectifier Applications

• Printed circuit board mounting in general-purpose power supply circuits
• Automation insertion systems requiring standardized surface mount components
• Single-phase rectification in industrial equipment operating within specified temperature ranges

Bridge Rectifier Procurement Notes

Verify component authenticity by checking the marking code structure against official Rectron documentation. Confirm RoHS compliance status through manufacturer certificates or datasheet declarations. Ensure storage conditions maintain integrity prior to soldering. Validate package dimensions match the DB-S footprint requirements for PCB layout compatibility.

Bridge Rectifier Selection Notes

Select this component when a 200 V reverse voltage rating aligns with circuit design requirements. Consider the 1.0 A continuous current capacity for load expectations. Evaluate thermal management needs based on the specified junction-to-ambient thermal resistance. Verify that the surface mount DB-S package fits the available board space constraints.

Bridge Rectifier Part Context

This part belongs to the DB101S through DB107S series, which share identical physical dimensions and electrical characteristics except for voltage ratings. The series offers a standardized solution for single-phase bridge rectification across multiple voltage levels ranging from 50 V to 1000 V.

Bridge Rectifier Replacement Considerations

Direct substitutes must match the DB-S package, 1.0 A current rating, and 200 V reverse voltage specification. Verify equivalent thermal resistance and forward voltage drop characteristics to ensure circuit performance parity.
