GBU1507

Overview

The GBU1507 is a single-phase standard bridge rectifier manufactured by Taiwan Semiconductor Corporation. It utilizes the GBU-4 through-hole package and provides an average forward rectified current of 15 A with a peak repetitive reverse voltage (Vrrm) of 1000 V. The device features a maximum non-repetitive peak forward surge current (Ifsm) of 600 A at 1.0 ms. Electrical characteristics include a maximum forward voltage drop of 1.1 V at rated current and a maximum reverse leakage current of 5 µA. It operates within a junction temperature range of -55°C to +150°C.

Feature Summary

• High surge current capability designed for transient survival in computing and lighting applications
• Direct upgrade compatibility with existing GBU footprints across 50 V to 1000 V ratings
• UL recognized component status to facilitate final product approval

Applications

• Switched-mode power supplies (SMPS)
• Battery chargers
• Lighting power supplies
• Television sets
• Adapters

Procurement Notes

Verify the specific manufacturer part number against official datasheets before ordering, as suffixes may indicate variations in packaging or compliance standards. Confirm RoHS and halogen-free status requirements match project specifications. Check for any recent product change notifications that might affect pinout or material composition. Ensure the supplier source is authorized to guarantee authenticity and traceability.

Selection Notes

Select this component when high reverse voltage resilience is required without increasing bill-of-materials costs compared to lower voltage variants. The 1000 V rating offers design margin for universal input power supplies meeting IEC61000-4-x and IEEE C62.XX oscillatory waveforms. Consider the 600 A surge rating for circuits prone to high inrush currents.

Part Context

This device belongs to the GBU150x series of standard bridge rectifiers from Taiwan Semiconductor. The series shares common physical dimensions and electrical performance profiles, differing primarily in peak reverse voltage ratings ranging from 50 V to 1000 V. This uniformity allows designers to use a single footprint for multiple voltage requirements.

Replacement Considerations

GBU1506 serves as a direct replacement if the circuit operates below 800 V reverse voltage. Other GBU150x variants may be substituted provided the reverse voltage rating meets or exceeds the application's peak inverse voltage requirements.
