G5SBA20-M3/51

Bridge Rectifier Overview

The G5SBA20-M3/51 is a glass-passivated single-phase bridge rectifier manufactured by Vishay General Semiconductor. It utilizes the GBU case style and provides a maximum average forward rectified output current of 6.0 A at a case temperature of 100 °C, or 2.8 A at an ambient temperature of 25 °C. The device supports a maximum repetitive peak reverse voltage (VRRM) of 200 V and withstands a peak forward surge current (IFSM) of 150 A. Electrical characteristics include a maximum instantaneous forward voltage of 1.05 V at 3.0 A and a maximum DC reverse current of 5.0 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 to confirm packaging details. The /51 designation indicates delivery in paper trays with a base quantity of 250 units. Confirm compliance requirements such as halogen-free status and RoHS adherence based on the M3 suffix before procurement.

Bridge Rectifier Selection Notes

Select this component when a 200 V blocking voltage and 6.0 A continuous current are required in a GBU package. Ensure thermal management aligns with the specified derating curves for heatsink or PCB mounting configurations. Validate that the 150 A surge capability meets the application's transient load requirements.

Bridge Rectifier Part Context

This part belongs to the G5SBA series of glass-passivated single-phase bridge rectifiers from Vishay. The series includes variants with different voltage ratings, specifically the G5SBA60 and G5SBA80 models. All members share the same GBU case style and similar electrical characteristics regarding current handling and thermal performance.

Bridge Rectifier Replacement Considerations

Direct substitutes within the same family include the G5SBA60-M3/51 and G5SBA80-M3/51, which offer higher voltage ratings but identical current and package specifications. Verify pinout compatibility and thermal resistance values when cross-referencing with other manufacturers' GBU bridge rectifiers.
