DF08ST-G

Bridge Rectifier Overview

The DF08ST-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 withstands a peak repetitive reverse voltage of 800 V. Key electrical parameters include a maximum forward voltage of 1.1 V at 1 A, a reverse leakage current of 10 µA, and a non-repetitive peak forward surge current of 30 A. It operates within a temperature range of -55°C to +150°C junction temperature.

Bridge Rectifier Procurement Notes

Verify the specific ordering suffix and manufacturer part number against official Comchip Technology documentation before purchase. Confirm RoHS compliance status and lead times directly with authorized distributors or the manufacturer. Ensure the procurement channel provides valid traceability and authenticity guarantees for semiconductor components.

Bridge Rectifier Selection Notes

Select this component when a 1 A rated single-phase bridge rectifier with 800 V reverse voltage capability is required in a surface-mount format. Compare the DFS-4 package dimensions against available PCB footprint constraints. Evaluate the 1.1 V forward voltage drop against system efficiency requirements relative to alternative rectifier technologies.

Bridge Rectifier Part Context

This component belongs to the DF08 series of bridge rectifiers from Comchip Technology. The series offers various voltage ratings while maintaining consistent current handling and package form factors. The DF08ST-G specifically addresses high-voltage requirements within the standard 1 A SMD bridge rectifier category.

Bridge Rectifier Replacement Considerations

Cross-reference with other manufacturers offering DFS-4 packaged 1 A / 800 V bridge rectifiers. Verify pinout compatibility and physical dimensions before substitution. Ensure equivalent electrical characteristics such as forward voltage and reverse leakage are met.
