DF02MA-E3/45

Bridge Rectifier Overview

The DF02MA-E3/45 is a single-phase bridge rectifier manufactured by Vishay General Semiconductor - Diodes Division. It utilizes standard silicon technology and features the DFS surface-mount package. The device supports a maximum repetitive peak reverse voltage of 200 V and an average forward rectified current of 1 A per terminal. It exhibits a forward voltage drop of 1.1 V at 1 A and a maximum non-repetitive surge current capability of 20 A. The component operates within a junction temperature range of -55°C to +150°C and complies with RoHS 3 standards.

Bridge Rectifier Feature Summary

• Surface-mount construction in a compact DFS plastic case for automated PCB assembly
• High surge current capability designed to withstand transient overload conditions
• Low forward voltage drop characteristic for improved power efficiency
• Molded epoxy meets UL Flammability Rating 94V-0

Bridge Rectifier Applications

• General-purpose AC to DC conversion in low-power adapters
• Battery charging circuits for consumer electronics
• Power supplies for small appliances and office equipment

Bridge Rectifier Procurement Notes

Verify the specific suffix against official manufacturer documentation, as variations may indicate different packaging or compliance statuses. Confirm that the component matches the required electrical ratings for the target circuit design. Check for obsolescence notices or product change notifications prior to finalizing procurement plans to ensure long-term supply availability.

Bridge Rectifier Selection Notes

Select this component when a surface-mount bridge rectifier is required for 200 V applications with up to 1 A continuous current. Ensure the PCB footprint accommodates the DFS package dimensions. Consider thermal management requirements based on the expected ambient temperature and load duty cycle to maintain safe junction temperatures during operation.

Bridge Rectifier Part Context

This part belongs to the DF0xMA series of Vishay's surface-mount bridge rectifiers. The series offers various voltage ratings and current capacities in standardized packages. The E3 suffix denotes lead-free termination and RoHS compliance. The /45 suffix typically indicates specific tape-and-reel packaging configurations used for high-volume manufacturing processes.

Bridge Rectifier Replacement Considerations

Direct substitutes include other 1 A, 200 V surface-mount bridge rectifiers in compatible packages such as DFS or similar SMD footprints from manufacturers like Littelfuse or ON Semiconductor. Verify pinout compatibility and thermal characteristics before substitution.
