GBU1003

Overview

The GBU1003 is a standard bridge rectifier from the Taiwan Semiconductor GBU1001–GBU1007 series, rated for a repetitive peak reverse voltage of 200V. It provides an average forward current of 10A and supports surge peak forward currents up to 220A under single half-sine-wave conditions. The device operates within a junction temperature range of -55°C to +150°C. Electrical characteristics include a maximum forward voltage of 1.1V at 10A and a typical reverse current of 5µA at 25°C. The component utilizes a GBU plastic package with matte tin-plated leads.

Feature Summary

• High case dielectric strength of 1500VRMS
• High surge current capability
• Typical reverse leakage current less than 0.1μA

Applications

• Switching mode power supply (SMPS)
• Adapters
• Lighting application

Procurement Notes

Verify the specific ordering code suffix when purchasing. The base part number GBU1003 denotes the standard version packaged in tubes of twenty units. An 'H' suffix indicates AEC-Q101 qualification. Confirm that the required automotive reliability standards match the selected variant before finalizing procurement orders.

Selection Notes

Select this component for circuits requiring a 200V reverse voltage rating and 10A continuous current handling. Ensure thermal management accounts for the junction-to-ambient thermal resistance of 21°C/W. Verify that the operating environment does not exceed the specified maximum junction temperature of 150°C during peak load conditions.

Part Context

This component belongs to the GBU1001 through GBU1007 product family manufactured by Taiwan Semiconductor Corporation. The series covers reverse voltage ratings ranging from 50V to 1000V while maintaining a consistent 10A forward current capacity across all models. The GBU1003 specifically addresses applications needing a 200V blocking capability.

Replacement Considerations

Direct substitutes within the same series include GBU1002 (100V) and GBU1004 (400V), provided their respective voltage ratings align with circuit requirements. Other manufacturers offering GBU package bridge rectifiers with matching 10A current and 200V reverse voltage specifications may also serve as functional replacements.
