Overview
The GBU8K-7000M3/45 is a single-phase bridge rectifier manufactured by Vishay Semiconductors. It features an 800 V peak reverse voltage and an average forward current of 8.0 A. The device utilizes glass passivation for the silicon chips and is housed in a GBU package designed for through-hole mounting with solder pin termination. Key electrical specifications include a maximum forward voltage of 1 V, a reverse leakage current of 5 uA, and a surge current rating of 200 A. The component operates within a temperature range of -55 °C to +150 °C.
Feature Summary
- Glass passivated silicon chips provide high reliability and long-term stability under various operating conditions.
- High surge current capability ensures robust performance during transient overload events.
- Low forward voltage drop contributes to improved efficiency and reduced power dissipation.
Applications
- AC to DC conversion in power supply circuits
- Bridge full-wave rectification in general-purpose electronics
- Adapter applications for consumer devices
Procurement Notes
Verify the exact part number against official Vishay documentation, as the suffix '7000' may indicate specific internal coding or packaging variations not universally standardized across all distributors. Confirm RoHS compliance status via the manufacturer's datasheet before integration into regulated assemblies.
Selection Notes
Select this component when an 8 A current rating and 800 V blocking voltage are required in a through-hole GBU package. Ensure the application environment stays within the specified -55 °C to +150 °C operating temperature range and that PCB layout accommodates the physical dimensions of the GBU housing.
Part Context
This component belongs to the GBU series of single-phase bridge rectifiers from Vishay Semiconductors. The series is characterized by its compact inline bridge configuration and glass passivation technology, offering a balance of high current handling and voltage resistance for industrial and commercial power applications.
Replacement Considerations
The GBU8K-E3/45 is listed as an alias for this part number in distributor databases. Verify functional equivalence regarding the 'E3' versus 'M3' lead-free designation and confirm that the '7000' suffix does not denote a distinct variant requiring separate qualification.
