G5SBA80-E3/51

Bridge Rectifier Overview

The G5SBA80-E3/51 is a glass passivated single-phase bridge rectifier manufactured by Vishay General Semiconductor - Diodes Division. It features a maximum average forward rectified output current of 6.0 A at a case temperature of 100 °C and a peak forward surge current capability of 150 A. The device supports a maximum repetitive peak reverse voltage (VRRM) of 800 V, with a corresponding maximum RMS reverse voltage of 560 V and a maximum DC blocking voltage of 800 V. 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 5.0 μA at 25 °C. The component operates within a junction and storage temperature range of -55 to +150 °C.

Bridge Rectifier Feature Summary

• Glass passivation provides mechanical strength and protects against mechanical stresses
• High surge current capability ensures robustness during transient load conditions
• High case dielectric strength of 1500 V RMS enhances electrical isolation safety

Bridge Rectifier Applications

• AC/DC bridge full wave rectification for monitors
• Power supply units in televisions and printers
• Switching mode power supplies and adapters
• Audio equipment and home appliances

Bridge Rectifier Procurement Notes

Verify the specific ordering suffix /51 corresponds to the paper tray packaging configuration containing 250 units per base quantity. Confirm that the E3 designation indicates RoHS compliance and halogen-free status as defined in the manufacturer's material categorization documentation. Ensure procurement channels source directly from authorized distributors to guarantee authenticity and traceability of the Vishay manufacturing lot.

Bridge Rectifier Selection Notes

Select this component when designing circuits requiring an 800 V reverse voltage rating for single-phase bridge rectification. The GBU package style is suitable for through-hole mounting on printed circuit boards. Consider the thermal resistance values and derating curves if operating near the maximum average forward current limit or in high ambient temperature environments without adequate heatsinking.

Bridge Rectifier Part Context

This part belongs to the G5SBA series of glass passivated single-phase bridge rectifiers, which also includes variants rated for 200 V and 600 V reverse voltages. All models in this series share identical physical dimensions, pin configurations, and general electrical characteristics such as forward voltage and surge current capabilities, differing primarily in their maximum repetitive peak reverse voltage ratings.

Bridge Rectifier Replacement Considerations

Direct functional substitutes within the same Vishay family include the G5SBA20-E3/51 and G5SBA60-E3/51, provided the system voltage requirements do not exceed 200 V or 600 V respectively. Cross-manufacturer replacements must match the GBU package outline, 6.0 A current rating, and 800 V reverse voltage specifications while adhering to similar thermal and mechanical constraints.
