DF06ST-HF

Bridge Rectifier Overview

The DF06ST-HF is a surface-mount glass-passivated bridge rectifier from Comchip Technology, rated for a maximum repetitive peak reverse voltage of 600V and a maximum average forward rectified current of 1.0A at 40°C ambient temperature. It features a low forward voltage drop of 1.1V at 1.0A DC and a typical thermal resistance of 40°C/W when mounted on a PCB with 0.5x0.5 inch copper pads. The device supports a peak forward surge current of 30A for an 8.3ms single half-sine wave and operates within a junction temperature range of -55°C to +150°C. It utilizes a DFS package with dimensions of approximately 10.3mm x 8.5mm.

Bridge Rectifier Feature Summary

• Glass passivation provides protection against mechanical stress and moisture ingress.
• Low forward voltage drop contributes to improved efficiency in power conversion circuits.
• High current capability allows for effective performance in compact designs.
• Suitable for automated assembly processes due to surface-mount packaging.

Bridge Rectifier Applications

• Printed circuit board implementations requiring compact rectification solutions.
• General-purpose AC to DC conversion in consumer electronics.
• Power supplies for devices with resistive or inductive loads.

Bridge Rectifier Procurement Notes

Verify the specific ordering suffix 'ST' confirms reel packaging rather than tube packaging, as indicated in the marking code table. Ensure the component meets RoHS compliance requirements if specified by the end application. Confirm that the supplier provides documentation verifying the Halogen-free status of the plastic material used in the encapsulation.

Bridge Rectifier Selection Notes

Select this component when a 600V reverse voltage rating is required for surface-mount applications. Consider the 1.0A continuous current limit and derating curves for temperatures above 40°C. Evaluate the thermal resistance characteristics relative to the available copper pad area on the PCB to ensure adequate heat dissipation during operation.

Bridge Rectifier Part Context

This part belongs to the DF005S-HF through DF10S-HF series of SMD glass-passivated bridge rectifiers. The series offers varying reverse voltage ratings from 50V to 1000V while maintaining a consistent 1.0A forward current capability. The DF06 variant specifically addresses mid-range voltage requirements within this standardized family of components.

Bridge Rectifier Replacement Considerations

Direct substitutes include other DF06S-HF variants from different manufacturers offering identical pinouts and electrical specifications. Verify that any replacement maintains the same DFS package dimensions and thermal characteristics to ensure compatibility with existing PCB layouts.
