GBU1007-K

Overview

The Taiwan Semiconductor GBU1007-K is a single-phase bridge rectifier in the GBU series, rated for a repetitive peak reverse voltage of 1000 V and an average forward current of 10 A. It features a quad configuration within a GBU plastic package designed for printed circuit board mounting. The device supports a junction temperature range from -55°C to +150°C and withstands a non-repetitive surge peak forward current of 200 A at 8.3 ms. Electrical characteristics include a maximum forward voltage of 1.1 V at 10 A and 25°C, with a typical junction-to-ambient thermal resistance of 7.6 °C/W.

Feature Summary

• High surge current capability for overload protection
• Molding compound meets UL 94V-0 flammability rating
• Matte tin plated leads ensure solderability per J-STD-002

Applications

• Switching mode power supply (SMPS)
• Adapters
• TV
• Monitor

Procurement Notes

Verify the specific ordering code matches the required voltage rating, as the suffix indicates the reverse voltage level within the GBU100x-K family. Confirm RoHS compliance and halogen-free status according to IEC 61249-2-21 standards during sourcing. Ensure the supplier provides documentation confirming UL Recognized File # E-326243 for safety certification purposes.

Selection Notes

Select this component when a 1000 V blocking capability is required for AC-to-DC conversion in PCB-mounted designs. Evaluate the thermal resistance parameters against the expected ambient temperature and load conditions to ensure the junction temperature remains within the specified operating range. Consider the physical dimensions of the GBU package for adequate spacing on the circuit board layout.

Part Context

This part belongs to the GBU1005-K through GBU1007-K series manufactured by Taiwan Semiconductor Corporation. The series offers standardized electrical ratings across different voltage classes, sharing identical mechanical footprints and thermal characteristics. The K suffix denotes the specific packaging and marking configuration used for this product line.

Replacement Considerations

Direct substitutes must match the 10 A current rating, 1000 V reverse voltage, and GBU package type. Verify that alternative components meet the same UL recognition requirements and thermal performance specifications.
