DBF310-13

Bridge Rectifier Overview

The DBF310-13 is a discontinued 3A surface-mount glass passivated bridge rectifier manufactured by Diodes Incorporated. It features a peak repetitive reverse voltage of 1,000V and an average rectified output current of 3.0A at a case temperature of +120°C. The forward voltage drop ranges from 0.88V to 1.0V depending on the current level. Non-repetitive peak forward surge current capability reaches 110A for an 8.3ms half-sine wave. The device utilizes a DBF package with lead-free matte tin finish terminals.

Bridge Rectifier Feature Summary

• Glass passivated die construction ensures stable electrical performance
• Miniature DBF package design optimizes printed circuit board space utilization
• Low leakage current characteristics enhance efficiency in high-voltage applications
• Surge overload rating supports transient current handling up to 110A peak

Bridge Rectifier Applications

• AC to DC bridge full wave rectification for switch mode power supplies
• LED lighting systems requiring robust rectification components
• Battery chargers and home appliances utilizing surface mount technology
• Telecommunication equipment power supply circuits

Bridge Rectifier Procurement Notes

This component is officially obsolete and has been discontinued by the manufacturer. No new production units are available through authorized channels. Engineers must verify end-of-life status before finalizing designs. Sourcing should focus exclusively on replacement parts or alternative suppliers holding existing stock, as original manufacturing has ceased permanently.

Bridge Rectifier Selection Notes

Designers should evaluate the MSB30M-13 as the designated successor part number provided by Diodes Incorporated. Verify that the replacement meets all required voltage, current, and thermal specifications for the target application. Ensure compatibility with existing PCB footprints and assembly processes when transitioning from the obsolete DBF310-13 to the recommended substitute.

Bridge Rectifier Part Context

The DBF310 belongs to Diodes Incorporated's line of surface-mount bridge rectifiers designed for general-purpose power conversion. Marked with 'DBF310' on the body, it was packaged in tape and reel format containing 3,000 units per carrier. The product adhered to RoHS directives and utilized halogen-free materials for environmental compliance during its active lifecycle.

Bridge Rectifier Replacement Considerations

Diodes Incorporated explicitly recommends the MSB30M-13 as the direct replacement for this obsolete component. Verify pinout compatibility and thermal resistance values before implementation.
