G5SBA80-M3/51

Bridge Rectifier Overview

The G5SBA80-M3/51 is a glass passivated single-phase bridge rectifier from Vishay General Semiconductor, utilizing the GBU case style. It provides a maximum repetitive peak reverse voltage of 800 V and supports a maximum average forward rectified output current of 6.0 A at a case temperature of 100 °C. The device features a peak forward surge current capability of 150 A for a single sine wave superimposed on rated load. Electrical characteristics include a maximum instantaneous forward voltage of 1.05 V per diode at 3.0 A and a maximum DC reverse current of 5 μA at 25 °C. The component operates within a junction and storage temperature range of -55 to +150 °C.

Bridge Rectifier Procurement Notes

Verify the specific ordering suffix against official documentation to confirm compliance requirements. The M3 designation indicates halogen-free and RoHS-compliant commercial grade material categorization. Confirm the /51 suffix corresponds to the paper tray delivery mode with a base quantity of 250 units as specified in the manufacturer's ordering information section.

Bridge Rectifier Selection Notes

Select this component when an 800 V blocking voltage is required for single-phase bridge rectification. Ensure the thermal design accounts for the 6.0 A rating at a case temperature of 100 °C or derate the current appropriately for higher ambient temperatures. Verify that the GBU package dimensions align with the printed circuit board layout constraints.

Bridge Rectifier Part Context

This part belongs to the G5SBA series of glass passivated single-phase bridge rectifiers manufactured by Vishay General Semiconductor. The series includes variants with different voltage ratings, specifically 200 V (G5SBA20), 600 V (G5SBA60), and 800 V (G5SBA80). All variants share identical mechanical packaging and general electrical characteristics, differing primarily in their maximum repetitive peak reverse voltage specifications.

Bridge Rectifier Replacement Considerations

Direct substitutes within the same family include G5SBA80-E3/51 for standard RoHS compliance without halogen-free requirements. Other voltage variants such as G5SBA60 or G5SBA20 are not electrically interchangeable due to lower reverse voltage ratings.
