GBU6J-M3/51

Overview

The GBU6J-M3/51 is a glass passivated single-phase bridge rectifier manufactured by Vishay General Semiconductor. It features a maximum repetitive peak reverse voltage (VRRM) of 600 V and an average forward rectified output current (IF(AV)) of 6.0 A at a case temperature of 90 °C, or 3.8 A in free air. The device supports a peak forward surge current (IFSM) of 175 A and exhibits a maximum instantaneous forward voltage drop (VF) of 1.0 V at 6.0 A. Operating junction and storage temperatures range from -55 °C to +150 °C. The component utilizes the GBU surface-mount package with matte tin-plated leads.

Feature Summary

• Glass passivation provides long-term stability and protection against mechanical stresses.
• High surge current capability ensures robustness during transient load conditions.
• High case dielectric strength of 1500 V RMS offers enhanced isolation safety.

Applications

• AC/DC bridge full wave rectification for monitors
• Switching mode power supplies and adapters
• Home appliances and audio equipment

Procurement Notes

Verify the specific ordering suffix to confirm packaging format. The /51 designation indicates delivery in paper trays with a base quantity of 250 units. Confirm RoHS compliance and halogen-free status requirements match the M3 suffix specifications before finalizing procurement orders.

Selection Notes

Select this component when a 600 V blocking voltage is required for general-purpose rectification. Ensure thermal management aligns with the specified derating curves, as the average forward current drops significantly in free-air PCB mounting compared to heatsink-mounted configurations.

Part Context

This part belongs to the GBU6 series of Vishay single-phase bridge rectifiers. The series includes variants with different voltage ratings ranging from 50 V to 1000 V, sharing identical physical dimensions and current handling capabilities. The M3 suffix denotes a halogen-free, RoHS-compliant commercial grade product.

Replacement Considerations

Cross-reference other GBU6 series part numbers such as GBU6K or GBU6G if higher voltage ratings are acceptable. Verify that alternative bridge rectifiers maintain the same GBU footprint and pinout configuration to ensure compatibility with existing printed circuit board layouts.
