Overview
The GBU4B-M3/51 is a single-phase bridge rectifier manufactured by Vishay General Semiconductor - Diodes Division. It features a peak repetitive reverse voltage of 400 V and an average forward rectified current rating of 4 A. The device utilizes the SUPERECTIFIER design for high reliability and includes cavity-free glass-passivated junctions. It is housed in a GBU surface-mount package, providing isolation between terminals and the case. The component operates within a junction temperature range of -55 °C to +150 °C.
Feature Summary
- SUPERECTIFIER structure ensures high reliability under demanding conditions
- Cavity-free glass-passivated junction enhances durability
- Isolated terminal configuration allows direct mounting to heatsinks
Applications
- General-purpose power supply circuits
- AC-DC conversion modules
- Battery charging systems
Procurement Notes
Verify the specific ordering suffix against official Vishay documentation to confirm exact packaging and compliance status. Confirm that the M3 designation indicates lead-free composition and RoHS compliance as per the manufacturer's standard definitions for this series.
Selection Notes
Select this component when a 4 A current rating and 400 V blocking voltage are required in a surface-mount form factor. Ensure the thermal management design accommodates the forward voltage drop at the expected load current to maintain junction temperatures within the specified operating range.
Part Context
This part belongs to the GBU series of single-phase bridge rectifiers from Vishay. The series is characterized by its robust SUPERECTIFIER technology and availability in various voltage ratings. The GBU4B variant specifically addresses applications requiring moderate current handling with a 400 V reverse voltage capability.
Replacement Considerations
Cross-reference with other Vishay GBU series parts for different voltage or current ratings. Verify pinout compatibility and thermal characteristics before substituting with components from other manufacturers.
