GBJ3504

Overview

The GBJ3504 is a single-phase standard bridge rectifier manufactured by SMC Diode Solutions. It features a peak reverse voltage of 400 V and an average rectified current of 35 A. The device utilizes a GBJ package, which corresponds to the 4-ESIP form factor for through-hole mounting. Forward voltage is specified at 1.1 V when conducting 35 A, while reverse leakage current remains at 5 µA under 400 V reverse bias conditions. The junction operating temperature range extends from -55°C to 150°C.

Feature Summary

• High current handling capability suitable for power supply applications
• Robust thermal performance with a wide junction temperature range
• Standard recovery characteristics for general-purpose rectification

Applications

• AC-DC converter circuits
• Power supply bridge rectification
• General purpose DC output stages

Procurement Notes

Verify the specific voltage rating against the application requirements, as the GBJ3504 is rated for 400 V. Confirm that the 35 A current capacity aligns with the load demands. Ensure the PCB layout accommodates the GBJ through-hole footprint dimensions. Check for RoHS compliance status if environmental regulations apply to the final assembly.

Selection Notes

Select this component when a 400 V blocking voltage and 35 A continuous current are required in a compact through-hole configuration. Compare forward voltage drop specifications against alternative brands to optimize efficiency. Consider the thermal resistance of the GBJ package for heat dissipation planning in enclosed environments.

Part Context

The GBJ3504 belongs to the GBJ series of single-phase bridge rectifiers from SMC Diode Solutions. This series is designed for high-current applications requiring reliable performance in standard recovery modes. The GBJ package provides a robust mechanical structure for through-hole mounting on printed circuit boards.

Replacement Considerations

Equivalent parts must match the 400 V reverse voltage, 35 A average current, and GBJ/4-ESIP package type. Verify forward voltage and leakage current specifications to ensure compatibility with existing thermal and electrical designs.
