DBF10G

Bridge Rectifier Overview

The DBF10G is a diffused junction silicon single-phase bridge rectifier manufactured by onsemi, originally under the SANYO brand. It provides an average rectified forward current of 1.0 A at 50 Hz with a resistive load mounted on a PCB. The component features a peak repetitive reverse voltage rating of 600 V. Electrical characteristics include a maximum forward voltage of 1.05 V at 0.5 A and a maximum reverse current of 10 μA at the rated reverse voltage. Thermal resistance values are specified as 16 °C/W (junction-to-lead) and 62 °C/W (junction-to-ambient). The device supports a junction temperature up to 150 °C and operates within a storage temperature range of -40 °C to +150 °C.

Bridge Rectifier Feature Summary

• Plastic molded structure for mechanical protection.
• Diffused junction silicon construction for reliable rectification.
• Designed for surface mount or through-hole PCB mounting applications.

Bridge Rectifier Applications

• General purpose AC to DC conversion in power supplies.
• Bridge rectification circuits in consumer electronics.
• Low-power industrial control systems requiring 1.0 A current handling.

Bridge Rectifier Procurement Notes

Verify the manufacturer origin, as the datasheet references SANYO Electric Co., Ltd., while the query specifies onsemi. Confirm the specific ordering suffix matches the required voltage rating (DBF10G indicates 600V). Ensure the package dimensions align with the target PCB footprint before procurement.

Bridge Rectifier Selection Notes

Select this component when a 1.0 A continuous current and 600 V reverse voltage rating are required. Consider the thermal resistance parameters for heat dissipation planning. Verify that the plastic molded package meets the environmental and mechanical requirements of the final assembly.

Bridge Rectifier Part Context

This component belongs to the DBF series of single-phase bridge rectifiers. Variants such as DBF10C offer different voltage ratings (200 V) within the same current class. The series utilizes a common plastic molded package design suitable for general-purpose rectification tasks across various electronic equipment categories.

Bridge Rectifier Replacement Considerations

Check for direct equivalents from other manufacturers offering 1.0 A, 600 V bridge rectifiers in compatible packages. Verify pinout compatibility and thermal performance metrics before substitution.
