DF03

Bridge Rectifier Overview

The SMC Diode Solutions DF03 is a standard recovery rectifier diode designed for general-purpose power conversion applications. It features a maximum average forward rectified current of 1.0 A and a peak repetitive reverse voltage rating of 200 V. The device utilizes a glass-passivated junction construction to ensure reliability under varying thermal conditions. Electrical characteristics include a maximum RMS reverse voltage of 140 V and a non-repetitive peak forward surge current capability of 30 A at 60 Hz. The component operates within a junction temperature range of -55°C to +150°C and is housed in the DO-201AD axial leaded package.

Bridge Rectifier Feature Summary

• Glass-passivated junction construction for enhanced environmental stability
• High surge current capability for robust transient protection
• Low forward voltage drop for improved efficiency

Bridge Rectifier Applications

• General purpose rectification in AC/DC converters
• Power supply input stages
• Battery charging circuits

Bridge Rectifier Procurement Notes

Verify the specific manufacturer datasheet for the exact electrical tolerances and mechanical dimensions before integration. Confirm that the DO-201AD package style matches the target PCB footprint requirements. Ensure the selected variant meets the necessary safety certifications for the intended end-use equipment.

Bridge Rectifier Selection Notes

Select this component when a 1.0 A current rating and 200 V blocking voltage are sufficient for the load. Consider the axial leaded form factor for through-hole mounting processes. Evaluate the thermal management requirements based on the specified junction temperature limits and ambient operating conditions.

Bridge Rectifier Part Context

The DF03 belongs to the series of standard silicon rectifier diodes manufactured by SMC Diode Solutions. This series provides reliable performance for low-to-medium power applications requiring basic rectification functions without the need for ultra-fast switching characteristics.

Bridge Rectifier Replacement Considerations

Equivalent parts from other manufacturers must match the 1.0 A average current, 200 V reverse voltage, and DO-201AD package type to ensure direct compatibility.
