G3SBA20-E3/45

Bridge Rectifier Overview

The G3SBA20-E3/45 is a glass passivated single-phase bridge rectifier manufactured by Vishay General Semiconductor - Diodes Division. It features an in-line circuit configuration within a GBU case style, designed for through-hole mounting. The device supports a maximum repetitive peak reverse voltage of 200 V and delivers a maximum average forward rectified output current of 4.0 A at a case temperature of 100 °C. Electrical characteristics include a maximum instantaneous forward voltage of 1.00 V at 2.0 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 high surge current capability and high case dielectric strength rated at 1500 V RMS.
• Molding compound meets UL 94 V-0 flammability rating with matte tin plated leads solderable per J-STD-002.
• E3 suffix indicates RoHS-compliant commercial grade material categorization.

Bridge Rectifier Applications

• General purpose AC/DC bridge full wave rectification
• Switching mode power supplies
• Monitors, TVs, printers, and adapters
• Audio equipment and home appliances

Bridge Rectifier Procurement Notes

Verify the specific ordering suffix against official documentation before procurement. The E3 suffix denotes RoHS compliance, while M3 indicates halogen-free status. Confirm package codes such as 45 (Tube) or 51 (Paper tray) match project requirements. Ensure technical parameters are validated for each application by customer experts prior to implementation.

Bridge Rectifier Selection Notes

Select this component based on the 200 V reverse voltage rating and 4.0 A average forward current capacity. Consider thermal resistance values when designing heatsinking or PCB copper pad layouts. Verify that the operating environment stays within the specified -55 to +150 °C junction temperature range. Evaluate derating curves if ambient temperatures exceed standard conditions.

Bridge Rectifier Part Context

This part belongs to the G3SBA series alongside G3SBA60 and G3SBA80 variants. All share identical mechanical dimensions and electrical characteristics except for the maximum repetitive peak reverse voltage ratings. The GBU package provides a standardized footprint for general-purpose rectification applications across various consumer electronics.

Bridge Rectifier Replacement Considerations

Direct substitutes within the same family include G3SBA60-E3/45 and G3SBA80-E3/45. These alternatives offer higher voltage ratings of 600 V and 800 V respectively while maintaining the same current and thermal specifications.

Bridge Rectifier FAQ

What is the maximum non-repetitive peak forward surge current?

The maximum non-repetitive peak forward surge current is 80 A for a single sine-wave superimposed on rated load.

How is polarity indicated on the component body?

Polarity is marked on the front side of the case, with the positive lead identified by a beveled corner.

What is the typical thermal resistance from junction to ambient?

The typical thermal resistance from junction to ambient is 26 °C/W when units are mounted on a PCB with 0.5" x 0.5" copper pads.
