Overview
The GBU1504 is a single-phase bridge rectifier manufactured by SMC Diode Solutions, designed for general-purpose power conversion applications. It features a maximum repetitive peak reverse voltage of 400 V and an average forward rectified current rating of 15 A. The device utilizes standard silicon technology and is housed in a GBU (4-ESIP) through-hole package. Key electrical characteristics include a maximum forward voltage drop of 1.1 V at 15 A and a maximum non-repetitive surge current capability of 300 A. The component operates within a junction temperature range of -55°C to +150°C.
Feature Summary
- High thermal stability with a wide operating junction temperature range up to 150°C
- Robust surge overload protection capability for transient current handling
- Low forward voltage drop for improved efficiency in power supply circuits
Applications
- AC-DC power supply units
- Battery chargers
- General-purpose rectification in industrial equipment
Procurement Notes
Verify the specific manufacturer part number against official datasheets to ensure compatibility with design requirements. Confirm that the 400 V reverse voltage rating meets the circuit's peak inverse voltage demands. Check package dimensions for the GBU form factor to ensure proper PCB footprint alignment during assembly.
Selection Notes
Select this component when a 15 A current rating and 400 V blocking voltage are required in a through-hole configuration. Compare the 1.1 V forward voltage drop against system efficiency targets. Ensure the thermal management strategy supports the specified junction temperature limits under continuous load conditions.
Part Context
The GBU1504 belongs to the GBU series of single-phase bridge rectifiers from SMC Diode Solutions. This series is characterized by its compact GBU package and high current density. It serves as a fundamental building block for converting alternating current to direct current in medium-power electronic systems.
Replacement Considerations
Compatible substitutes include other 15 A, 400 V single-phase bridge rectifiers in the GBU or similar through-hole packages. Verify pinout compatibility and thermal resistance values before substitution.
