DF08-G

Bridge Rectifier Overview

The DF08-G is a single-phase bridge rectifier manufactured by Comchip Technology, designed for surface-mount applications. It utilizes silicon technology and features the DFS-4 package with solder pad termination. The device supports an average forward current of 1 A and offers a peak reverse voltage rating of 800 V. Key electrical characteristics include a maximum forward voltage drop of 1.1 V at rated current and a reverse leakage current of 10 uA. It withstands a maximum surge current of 30 A and operates within a temperature range of -55 C to +150 C.

Bridge Rectifier Feature Summary

• Surface-mount construction in a compact DFS-4 package for automated assembly
• High voltage blocking capability suitable for demanding power supply circuits
• Robust thermal performance allowing operation up to 150 C junction temperature

Bridge Rectifier Applications

• General purpose AC to DC conversion in power supplies
• Bridge rectification in low-power electronic devices
• Polarity protection circuits requiring high reverse voltage tolerance

Bridge Rectifier Procurement Notes

Verify the specific suffix against official datasheets to confirm exact ratings, as variations may exist within the product line. Confirm RoHS compliance status and lead times directly with authorized distributors or the manufacturer prior to ordering. Ensure storage conditions meet moisture sensitivity level requirements to maintain component integrity before reflow soldering.

Bridge Rectifier Selection Notes

Select this component when a surface-mount bridge rectifier with 800 V reverse voltage and 1 A continuous current is required. Compare the DFS-4 footprint against available PCB space constraints. Evaluate thermal management needs given the 150 C maximum operating temperature limit and ensure the application does not exceed the 30 A surge current rating during startup or fault conditions.

Bridge Rectifier Part Context

This part belongs to the DF08 series of single-phase bridge rectifiers from Comchip Technology. The series provides various voltage ratings while maintaining consistent current handling and package dimensions. The DFS-4 package allows for efficient board space utilization compared to through-hole alternatives, making it suitable for modern compact electronics designs.

Bridge Rectifier Replacement Considerations

Compatible replacements must match the 1 A current, 800 V reverse voltage, and DFS-4 surface-mount package. Verify that substitute components offer equivalent forward voltage and surge current capabilities to ensure circuit reliability without redesign.
