DBB08G-TM-E

Bridge Rectifier Overview

The DBB08G-TM-E is a single-phase bridge rectifier manufactured by onsemi. It features a plastic molded structure and an ultrasmall DIP4 package designed to minimize footprint in applied sets. The device utilizes glass passivation for high reliability. Key electrical specifications include a peak reverse voltage of 600 V and an average rectified current of 0.8 A when mounted on an alumina board, or 0.5 A on a PCB. The forward voltage is typically 1.05 V at 0.4 A, with a maximum reverse current of 10 μA. Thermal resistance is rated at 76 °C/W on alumina and 134 °C/W on PCB.

Bridge Rectifier Feature Summary

• Ultrasmall DIP4 package facilitates compact circuit design
• Glass passivation ensures high reliability
• Plastic molded structure supports miniaturization

Bridge Rectifier Applications

• General-purpose AC to DC conversion circuits
• Power supply modules requiring small form factors
• Bridge rectification in consumer electronics

Bridge Rectifier Procurement Notes

Verify the ordering number EN2772C matches the specific procurement requirements. Confirm the DIP4 package type and Pb-Free status align with assembly standards. Ensure the supplier documentation references the correct datasheet version A2772-3/3 for accurate technical parameters.

Bridge Rectifier Selection Notes

Select this component for applications requiring a 600 V reverse voltage rating and up to 0.8 A average current. Consider thermal constraints carefully, as the average current drops to 0.5 A when mounted on standard PCBs compared to alumina boards. Verify that the ultrasmall DIP4 package fits the available board space.

Bridge Rectifier Part Context

This part belongs to the DBB08 series of single-phase bridge rectifiers from onsemi. The series is characterized by its glass passivation and plastic molded construction. The DBB08G-TM-E specifically denotes the DIP4 package variant with lead-free compliance, intended for surface mount or through-hole integration depending on the specific board layout.

Bridge Rectifier Replacement Considerations

Check for other DBB08 variants with different suffixes if package or environmental compliance differs. Ensure any substitute maintains the 600 V peak reverse voltage and comparable current ratings.
