DB15-04

Bridge Rectifier Overview

The DB15-04 is a single-phase silicon bridge rectifier manufactured by Diotec Semiconductor. It features a maximum average forward rectified current of 15 A and a repetitive peak reverse voltage (VRRM) of 400 V. The device utilizes an avalanche-rated design for enhanced robustness against transient overvoltages. It is housed in the DO-201AD axial through-hole package, suitable for general-purpose power supply applications requiring reliable AC-to-DC conversion.

Bridge Rectifier Feature Summary

• Avalanche-rated construction for improved surge handling capability
• High thermal stability with a maximum junction temperature of +175°C
• Axial leaded package designed for easy insertion into PCB layouts

Bridge Rectifier Applications

• General-purpose AC to DC power supply circuits
• Battery charging systems
• Industrial control power modules

Bridge Rectifier Procurement Notes

Verify the specific manufacturer datasheet for the DB15-04 to confirm exact thermal resistance values and detailed electrical limits. Ensure the procurement source provides official documentation confirming the avalanche rating and compliance with RoHS directives before finalizing orders.

Bridge Rectifier Selection Notes

Select this component when a 15 A current rating and 400 V blocking voltage are required in an axial package. Consider the avalanche capability if the application involves significant inductive loads or voltage spikes that exceed standard non-avalanche ratings.

Bridge Rectifier Part Context

This part belongs to Diotec's series of single-phase bridge rectifiers. It shares the same physical footprint and current handling characteristics as other variants in the family but differs in its reverse voltage rating and specific avalanche certification compared to lower-voltage models.

Bridge Rectifier Replacement Considerations

Substitutes must match the 15 A current rating, 400 V minimum reverse voltage, and DO-201AD package. Verify that alternative bridge rectifiers offer comparable avalanche ratings if surge protection is critical to the circuit design.
