GBU8D-E3/45

Overview

The GBU8D-E3/45 is a single-phase bridge rectifier from Vishay's GBU8 series, designed for through-hole mounting. It features a glass-passivated junction and operates within a temperature range of -55°C to +150°C TJ. The device supports an average forward current (If) of 8A and withstands a peak repetitive reverse voltage (Vrrm) of 200V. Key electrical parameters include a maximum forward voltage (Vf) of 1V at If, a non-repetitive peak forward surge current (Ifsm) of 200A, and a maximum reverse leakage current (Ir) of 5μA. The component utilizes the GBU package with dimensions of 22.3mm in length and 18.8mm in height.

Feature Summary

• Glass passivated junction construction for enhanced reliability
• High surge current capability suitable for transient protection
• Low forward voltage drop for improved efficiency

Applications

• General purpose rectification in power supplies
• AC to DC conversion circuits
• Battery charging systems

Procurement Notes

Verify the specific suffix /45 corresponds to the tube packaging configuration when sourcing. Confirm RoHS compliance status via the manufacturer datasheet as regulatory requirements evolve. Ensure the procurement channel provides authentic Vishay components to avoid counterfeit risks. Cross-reference the full part number with official distributor catalogs to confirm availability and lead times prior to ordering.

Selection Notes

Select this component when a 200V rating is required for single-phase applications. The 8A continuous current rating suits moderate power levels. Consider the GBU package size for PCB layout constraints. Verify thermal management needs given the 150°C junction temperature limit. Compare against other GBU8 variants if higher voltage ratings are necessary.

Part Context

This part belongs to the Vishay GBU8 series of bridge rectifiers. The series offers various voltage ratings while maintaining consistent mechanical dimensions and current handling capabilities. The GBU8D variant specifically targets 200V applications within this standardized form factor family.

Replacement Considerations

Direct substitutes may include other Vishay GBU8 series parts with identical current ratings but different voltage codes. External manufacturers offering equivalent GBU packages should be evaluated for pin compatibility and thermal performance. Verify that any replacement meets the same glass passivation and RoHS standards.
