• High surge current capability allows the device to withstand transient overload conditions without failure.
• Plastic molding compound meets UL flammability classification standards for safety compliance.

Applications

• Adapters and chargers for consumer electronics
• Battery charging circuits in automotive systems
• General-purpose DC power supplies

Procurement Notes

Verify the manufacturer part number against official Taiwan Semiconductor documentation to confirm specifications. Ensure the ordering suffix matches the required packaging configuration. Cross-reference datasheet parameters with system requirements before integration. Confirm RoHS compliance status if restricted substances are a constraint for the final assembly.

Selection Notes

Select this component when a 4.0A current rating and 50V reverse voltage blocking capability are required. The GBU package offers a balance of current handling and board space efficiency. Consider thermal management requirements based on the expected ambient temperature and load duty cycle. Verify that the lead-free terminal plating meets the soldering process specifications of the manufacturing line.

Part Context

This component belongs to the GBU series of single-phase bridge rectifiers from Taiwan Semiconductor. The series includes variants with different voltage ratings while maintaining the same 4.0A current capacity and physical footprint. These devices are widely used in industrial and commercial power conversion equipment where reliable rectification is critical.

Replacement Considerations

Compatible substitutes include the GBU401 from Diodes Incorporated and other manufacturers producing equivalent 4A/50V glass-passivated bridge rectifiers in the GBU package. Verify pinout compatibility and thermal characteristics before substitution.
