GBU402

Overview

The GBU402 is a single-phase bridge rectifier manufactured by SMC Diode Solutions. It features a maximum repetitive peak reverse voltage of 200 V and an average forward rectified current of 4 A. The device utilizes glass passivation for electrode isolation, meeting UL recognition standards. It is housed in the GBU package, which provides high power density and robust mechanical stability. The component operates within a junction temperature range of -55°C to +150°C and complies with RoHS3 directives.

Feature Summary

• Glass passivated electrodes provide stable electrical characteristics and protection against environmental variations.
• High current capability combined with low forward voltage drop ensures efficient power conversion.
• Mechanically robust GBU package design supports high power density applications.

Applications

• AC-DC converter circuits
• Power supply units
• Battery chargers

Procurement Notes

Verify the specific ordering suffix to confirm the packaging format, such as tube or tape-and-reel configuration. Confirm that the requested variant matches the required voltage and current ratings for the target application. Ensure compliance with relevant environmental regulations like RoHS3 if applicable to the project requirements.

Selection Notes

Select this component when a 200 V reverse voltage rating and 4 A continuous current are required in a surface-mount compatible through-hole package. Consider the thermal management capabilities of the GBU housing for the expected operating environment. Verify pinout compatibility with the intended PCB layout before finalizing the design.

Part Context

The GBU402 belongs to the GBU series of single-phase bridge rectifiers from SMC Diode Solutions. This series is designed for general-purpose rectification in medium-power applications. The GBU package offers a compact footprint relative to its current handling capacity, making it suitable for space-constrained designs requiring reliable AC-to-DC conversion.

Replacement Considerations

Check for direct equivalents from other manufacturers offering identical 200 V, 4 A specifications in the GBU package. Verify pin compatibility and thermal performance metrics to ensure seamless integration without redesigning the host circuit board.
