DB101-G

Bridge Rectifier Overview

The DB101-G is a single-phase bridge rectifier manufactured by Comchip Technology, designed for general-purpose power supply applications. It features an average forward current rating of 1 A and a maximum repetitive peak reverse voltage of 50 V. The device utilizes glass passivation for junction protection and is housed in the DB-4 surface-mount package with solder pin termination. Key electrical characteristics include a maximum RMS reverse voltage of 35 V, a peak inverse voltage of 70 V, and a surge forward current capacity of 30 A. The component operates within a temperature range of -55°C to +150°C, with a typical forward voltage drop of 1.1 V at rated current.

Bridge Rectifier Feature Summary

• Glass passivated junctions provide stable performance and reliable operation under varying thermal conditions.
• Surface-mount DB-4 package design facilitates automated assembly and compact circuit board layouts.
• High surge current capability ensures robustness against transient overloads during power-up or fault conditions.

Bridge Rectifier Applications

• General-purpose AC to DC conversion in low-power adapters
• Battery charging circuits for consumer electronics
• DC power supplies for small appliances

Bridge Rectifier Procurement Notes

Verify RoHS compliance status through official manufacturer documentation prior to integration, as regulatory markings may vary by production batch. Confirm that the specific ordering suffix matches the required lead-free specifications for your manufacturing process. Ensure that the supplier provides valid traceability records and original manufacturer data sheets to guarantee component authenticity and quality assurance standards are met.

Bridge Rectifier Selection Notes

Select this component when a low-current, low-voltage surface-mount bridge rectifier is required for space-constrained designs. Compare the 1 A current rating and 50 V reverse voltage limits against circuit requirements to ensure adequate headroom. Consider the DB-4 package dimensions for PCB footprint compatibility and verify that the operating temperature range aligns with the environmental conditions of the final application.

Bridge Rectifier Part Context

The DB101-G belongs to Comchip Technology's line of glass-passivated bridge rectifiers, which are engineered for reliability in standard electronic assemblies. This series offers a balance of performance and cost-effectiveness for mass-produced devices. The DB-4 package is widely adopted in the industry for its compact size and ease of mounting, making it suitable for a broad range of consumer and industrial products requiring efficient rectification.

Bridge Rectifier Replacement Considerations

Compatible substitutes include the DB101 from other manufacturers such as Rectron Semiconductor or HY Electronic, provided they match the 1 A / 50 V specifications and DB-4 package outline. Verify pinout compatibility and thermal characteristics before substitution to ensure seamless integration without redesigning the PCB layout.
