DBA40G

Bridge Rectifier Overview

The DBA40G is a diffused junction silicon diode manufactured by Sanyo Electric Co., Ltd. under the onsemi brand portfolio. It functions as a single-phase bridge rectifier with an average rectified current of 4.0 A and peak reverse voltages of 200 V or 600 V. The component features a plastic molded structure and glass passivation for high reliability. Electrical characteristics include a maximum forward voltage of 1.05 V at 2.0 A and a maximum reverse current of 10 μA. It supports a surge forward current of 80 A and operates within a junction temperature range up to 150 °C.

Bridge Rectifier Feature Summary

• Glass passivation provides enhanced reliability for the diffused junction silicon diode.
• Plastic molded structure ensures mechanical stability in power applications.

Bridge Rectifier Applications

• General-purpose rectification in power supply circuits
• Single-phase bridge rectifier configurations
• Industrial equipment requiring robust diode protection

Bridge Rectifier Procurement Notes

Verify the manufacturer designation, as the datasheet originates from Sanyo Electric Co., Ltd., while the product is listed under the onsemi brand. Confirm the specific voltage rating (200V or 600V) required for your application, as both variants fall under the DBA40 series. Ensure compliance with RoHS standards if applicable to your region. Cross-reference the ordering number ENN649D with official distributor catalogs to confirm current availability and exact part specifications before finalizing procurement.

Bridge Rectifier Selection Notes

Select the DBA40G variant based on the required peak reverse voltage, choosing between 200 V or 600 V ratings. Consider the thermal management requirements, as the average rectified current increases significantly when mounted on a 60x60x1.5mm³ aluminum fin compared to free-air operation. Verify that the surge forward current capability of 80 A meets the circuit's transient demands. Ensure the operating junction temperature remains within the specified 150 °C limit during design.

Bridge Rectifier Part Context

The DBA40 belongs to a series of diffused junction silicon diodes designed for general-purpose rectification. Manufactured originally by Sanyo Electric Co., Ltd., these components are now associated with the onsemi brand. The series offers various voltage ratings to suit different power supply needs, providing a reliable solution for converting AC to DC in standard electronic applications.

Bridge Rectifier Replacement Considerations

Consult official distributors for direct substitute part numbers. Generic equivalents may not match the specific glass passivation or surge current capabilities documented in the original datasheet.
