DBL157GH

Bridge Rectifier Overview

The DBL157GH is a single-phase bridge rectifier manufactured by Taiwan Semiconductor Corporation. It features a maximum average forward rectified current of 1.5 A and a maximum repetitive peak reverse voltage of 1000 V. The device utilizes glass passivation for junction protection and is housed in a low-profile DIP package with molded plastic construction rated UL 94V-0. It is qualified to the AEC-Q101 automotive standard, ensuring reliability under specified conditions.

Bridge Rectifier Feature Summary

• Glass passivated junctions provide reliable performance and protection against voltage transients.
• AEC-Q101 qualification ensures suitability for demanding automotive electronic applications.
• Low profile DIP packaging facilitates automated placement and efficient PCB mounting.

Bridge Rectifier Applications

• Automotive power supply circuits requiring high reliability.
• General-purpose AC to DC conversion in industrial equipment.
• Battery charging systems within vehicle electrical architectures.

Bridge Rectifier Procurement Notes

Verify the specific suffix 'H' confirms AEC-Q101 automotive qualification and 'G' indicates halogen-free green compound status. Confirm the package type matches the required low-profile DIP form factor for the target assembly. Ensure the 1000 V reverse voltage rating aligns with the circuit's peak inverse voltage requirements.

Bridge Rectifier Selection Notes

Select this component when an automotive-grade bridge rectifier is required for 1.5 A applications. The 1000 V rating provides sufficient margin for higher voltage AC inputs. The glass passivation offers superior stability compared to standard epoxy-passivated alternatives in harsh environments.

Bridge Rectifier Part Context

This part belongs to the DBL15-G series of glass passivated bridge rectifiers from Taiwan Semiconductor. The series covers various voltage ratings from 50 V to 1400 V while maintaining a consistent 1.5 A current capability and low-profile DIP footprint for standardized design integration.

Bridge Rectifier Replacement Considerations

Cross-reference with other AEC-Q101 qualified 1.5 A bridge rectifiers in low-profile DIP packages. Verify pinout compatibility and thermal characteristics before substituting with parts from different manufacturers.
