G3SBA20-E3/51

Bridge Rectifier Overview

The G3SBA20-E3/51 is a glass passivated single-phase bridge rectifier manufactured by Vishay General Semiconductor. It utilizes the GBU case style and contains four silicon diode elements configured for full-wave rectification. The device supports a maximum repetitive peak reverse voltage of 200 V, with corresponding RMS and DC blocking voltages of 140 V and 200 V respectively. It provides a maximum average forward rectified output current of 4.0 A at a case temperature of 100 °C, or 2.3 A at an ambient temperature of 25 °C when mounted on a PCB. The component withstands a peak forward surge current of 80 A and operates within a junction and storage temperature range of -55 °C to +150 °C.

Bridge Rectifier Feature Summary

• Glass passivated chip junction ensures reliable operation under standard conditions
• High surge current capability designed to handle transient electrical loads
• High case dielectric strength rated at 1500 V RMS for enhanced isolation
• Molding compound meets UL 94 V-0 flammability rating for safety compliance

Bridge Rectifier Applications

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

Bridge Rectifier Procurement Notes

Verify the specific ordering suffix to confirm packaging configuration. The /51 designation indicates a paper tray delivery mode with a base quantity of 250 units. Confirm RoHS compliance status and terminal plating specifications match the design requirements before finalizing procurement orders.

Bridge Rectifier Selection Notes

Select this component for general-purpose AC/DC conversion where a 200 V reverse voltage rating is sufficient. Ensure thermal management strategies account for the specified derating curves, as the average forward current decreases significantly at higher ambient temperatures. Verify that the mounting torque does not exceed the recommended limits to prevent mechanical damage.

Bridge Rectifier Part Context

This part belongs to the G3SBA series of glass passivated single-phase bridge rectifiers from Vishay. The series includes variants with different voltage ratings, specifically the G3SBA60 and G3SBA80 models, which offer 600 V and 800 V capabilities respectively while maintaining identical current ratings and package dimensions.

Bridge Rectifier Replacement Considerations

Direct functional substitutes within the same family include the G3SBA60-E3/51 and G3SBA80-E3/51. These alternatives share the same GBU package and 4.0 A current rating but provide higher reverse voltage blocking capabilities. Ensure the application voltage does not exceed the 200 V limit of the original part if substituting with lower-rated devices.
