GBU15D

Overview

The GeneSiC Semiconductor GBU15D is a single-phase glass passivated silicon bridge rectifier rated for a repetitive peak reverse voltage of 400 V. It supports an average forward rectified current of 15 A at a case temperature of 100 °C and withstands a peak forward surge current of 250 A under standard test conditions. The device features a maximum forward voltage drop of 1.05 V at 7.5 A and operates within a junction temperature range of -40 to 150 °C. It utilizes a molded epoxy resin package compliant with UL 94V-0 flammability standards.

Feature Summary

• Glass passivated chip junctions provide stable electrical characteristics and high reliability.
• Epoxy resin body meets UL 94V-0 flammability classification requirements.
• High surge overload rating ensures robustness against transient current events.
• Suitable for direct mounting on printed circuit boards without additional heatsinking.

Applications

• General purpose AC to DC conversion in power supplies
• Bridge rectification circuits in industrial equipment
• Power stages in consumer electronics requiring 400 V blocking capability

Procurement Notes

Verify the specific manufacturer origin, as the part number appears across multiple suppliers including GeneSiC Semiconductor, SECOS, and others. Confirm compliance with RoHS directives and check for halogen-free variants if required by project specifications. Ensure the supplier provides valid UL recognition documentation referencing file number E303851 for safety certification purposes.

Selection Notes

Select this component when a 400 V reverse voltage rating and 15 A continuous current capacity are required in a through-hole GBU package. Consider thermal resistance values of 22 °C/W (junction-to-ambient) or 5.0 °C/W (junction-to-case) based on the intended cooling method. Derate the forward current by 20% if the application involves capacitive loads rather than resistive ones.

Part Context

The GBU15D belongs to the GBU15 series of single-phase bridge rectifiers, which includes variants with different reverse voltage ratings such as GBU15A (50 V), GBU15B (100 V), and GBU15G (600 V). All members of this series share identical physical dimensions, current ratings, and packaging characteristics, differing primarily in their maximum repetitive peak reverse voltage specifications.

Replacement Considerations

Compatible substitutes include GBU15K from Galaxy Semi-Conductor Co Ltd and GBU15K from Daco Semiconductor Co Ltd. Verify that alternative sources maintain the same 400 V reverse voltage rating and 15 A current capacity before implementation.
