Overview
The GBU6K-E3/45 is a single-phase bridge rectifier manufactured by Vishay Semiconductors. It features an 800 V peak reverse voltage rating and supports an average forward current of 6 A. The device utilizes glass passivation for junction protection and is housed in a GBU through-hole package with solder pin termination. Key electrical parameters include a maximum forward voltage of 1 V, a surge current capacity of 200 A, and a reverse leakage current of 5 µA. It operates within a temperature range of -55°C to +150°C.
Feature Summary
- Glass passivated junctions provide mechanical strength and meet environmental requirements.
- High surge current capability designed to withstand transient overload conditions.
- Low forward voltage drop contributes to improved system efficiency.
Applications
- AC-DC power supply circuits
- Battery chargers
- General-purpose rectification
Procurement Notes
Verify the specific part number against official manufacturer documentation to ensure accuracy. Confirm that the component meets all required RoHS and REACH compliance standards for your region. Check for any recent product change notices or lifecycle status updates directly from the supplier before finalizing procurement plans.
Selection Notes
Select this component when an 800 V blocking voltage and 6 A continuous current are required in a standard through-hole configuration. Ensure the thermal management design accommodates the specified operating temperature range. Verify that the GBU footprint matches the PCB layout constraints for adequate spacing and mounting stability.
Part Context
This component belongs to the GBU8 series family of bridge rectifiers, which share similar physical dimensions and mounting characteristics. Variations within the series typically differ in voltage ratings and current capacities while maintaining the same package style and installation method for design flexibility.
Replacement Considerations
Direct substitutes may include other Vishay GBU series parts with matching voltage and current ratings, such as GBU6M-E3/45 for lower voltage applications. Cross-brand replacements require verification of pinout compatibility, thermal resistance, and electrical specifications against the original datasheet.
