Overview
The GBU8K-4E3/51 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 A. The device utilizes glass passivation for junction protection and is housed in a GBU through-hole package with solder pin terminations. Key electrical parameters include a maximum forward voltage of 1 V, a non-repetitive peak surge current 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 reliable operation under varying thermal conditions.
- High surge current capability supports robust performance during transient events.
- Through-hole mounting facilitates integration into standard PCB layouts.
Applications
- General purpose rectification in power supply circuits
- Inverter and converter input stages

Procurement Notes
Verify the specific ordering suffix against official Vishay documentation to confirm exact packaging and compliance status. Ensure the component matches the required voltage and current ratings for the target circuit design before procurement.
Selection Notes
Select this component when an 800 V rating and 8 A continuous current are required in a GBU package. Consider the 150 °C maximum junction temperature for high-thermal environments. Verify that the through-hole form factor aligns with the assembly process.
Part Context
This part belongs to the GBU8 series of single-phase bridge rectifiers from Vishay. The series offers various voltage ratings while maintaining consistent mechanical dimensions and electrical characteristics such as forward voltage and surge capability across different models.
Replacement Considerations
Check for direct substitutes within the GBU8 series with matching voltage ratings. Ensure any replacement maintains the same GBU package footprint and pin configuration to avoid PCB redesign.
