GBU1505

Overview

The GBU1505 is a single-phase bridge rectifier manufactured by Taiwan Semiconductor Corporation, designed for general-purpose AC-to-DC power conversion. It features an average forward rectified current of 15 A and a maximum repetitive peak reverse voltage of 50 V. The device utilizes glass passivation for junction protection and is housed in a GBU (DO-201AB) package suitable for through-hole mounting. Key electrical characteristics include a maximum RMS input voltage of 35 V, a surge forward current rating of 200 A, and a maximum DC blocking voltage of 50 V. Operating temperatures range from -55 °C to +150 °C.

Feature Summary

• Glass passivated junctions provide robust environmental protection and long-term reliability under varying thermal conditions.
• High surge current capability ensures stability during transient load events and startup phases.
• Low forward voltage drop contributes to improved overall system efficiency and reduced heat generation.

Applications

• General-purpose AC/DC power supply circuits
• Battery chargers and adapters
• Inverter freewheeling diode applications

Procurement Notes

Verify the manufacturer marking on the component body to confirm it reads 'Taiwan Semiconductor' or the specific logo associated with TSC. Ensure the part number printed matches GBU1505 exactly. Check for compliance markings such as RoHS if required by your design specifications. Confirm the package type is standard GBU/DO-201AB before integration into PCB layouts.

Selection Notes

Select this component when a 15 A continuous current rating and 50 V reverse voltage are sufficient for the application. Consider the GBU package size for available board space. Evaluate thermal management requirements based on the forward voltage drop at expected load currents. Compare against other GBU series variants if higher voltage ratings like 100 V or 200 V are needed instead.

Part Context

This component belongs to the GBU series of single-phase bridge rectifiers, which are widely used in industrial and consumer electronics. The series offers various current and voltage combinations to suit different power levels. The GBU1505 specifically targets low-voltage, high-current applications where cost-effectiveness and reliability are prioritized over ultra-fast switching speeds.

Replacement Considerations

Direct replacements must match the 15 A current and 50 V voltage ratings. Other manufacturers producing GBU1505 equivalents can be considered if pin compatibility and thermal performance are verified. Ensure any substitute maintains the same glass passivation technology and package dimensions for seamless mechanical integration.
