GBU403HD2G

Overview

The GBU403HD2G is a single-phase bridge rectifier diode manufactured by Taiwan Semiconductor Corporation. It utilizes silicon technology and features a GREEN plastic GBU package with four terminals. The device provides a maximum average forward rectified current of 4A and a repetitive peak reverse voltage (VRRM) of 300V. It operates within a junction temperature range of -55°C to +150°C and supports a non-repetitive peak forward surge current of 150A.

Feature Summary

• Glass passivated die for enhanced environmental stability
• Green compound packaging compliant with halogen-free standards
• High case dielectric strength for reliable isolation

Applications

• Printed circuit board mounting in power supplies
• General-purpose AC to DC conversion circuits
• Low-cost construction applications requiring high reliability

Procurement Notes

Verify the specific suffix 'HD2' against official Taiwan Semiconductor documentation, as standard datasheets typically list 'GBU403G'. Confirm that the 'HD' designation does not indicate a specialized variant or different pinout configuration compared to the standard GBU403 series before procurement.

Selection Notes

Select this component for applications requiring a 4A continuous current rating and 300V reverse voltage blocking capability. Ensure the design accommodates the GBU through-hole footprint and verify thermal management requirements for operation up to 150°C junction temperature.

Part Context

This part belongs to the GBU401-GPU407 series of single-phase bridge rectifiers from Taiwan Semiconductor. These components are designed for general-purpose power supply applications, offering a balance of performance and cost-effectiveness through molded plastic construction and lead-free terminal plating.

Replacement Considerations

Standard equivalents include the GBU403G. Verify compatibility with other generic GBU-4A/300V bridge rectifiers from manufacturers such as Littelfuse or Vishay, ensuring identical pinout and thermal characteristics.
