GBU8A-T

Overview

The GBU8A-T is a single-phase bridge rectifier manufactured by Diotec Semiconductor, designed for general-purpose power supply applications. It features a silicon construction with glass passivation for reliable operation. The device supports a maximum repetitive peak reverse voltage of 50 V and delivers an average forward rectified current of 8.0 A at 45°C ambient temperature. Housed in the GBU plastic package, it offers high surge overload capability with a peak forward surge current rating of 200 Amperes. The component is suitable for PCB mounting and operates within a junction temperature range of -55°C to +175°C.

Feature Summary

• Glass passivated junctions ensure high reliability and long-term stability under varying thermal conditions.
• Molded plastic case meets UL flammability classification 94V-O for enhanced safety standards.
• High surge current capacity allows robust performance during transient electrical events.

Applications

• General-purpose AC to DC conversion in power supplies
• Battery chargers requiring low voltage rectification
• Adapters and inverters operating within 50 V reverse voltage limits

Procurement Notes

Verify the specific ordering suffix against the manufacturer's latest documentation to confirm tape-and-reel packaging versus bulk availability. Confirm that the GBU-8 series designation aligns with the required 8 A current rating and 50 V voltage class for your circuit design. Ensure compliance with RoHS directives if applicable to your manufacturing region.

Selection Notes

Select this component when an 8 A continuous current rating and 50 V blocking voltage are required in a through-hole GBU package. Evaluate thermal management requirements based on the 45°C ambient temperature derating curve. Consider the 200 A surge rating for inductive load switching scenarios where high initial current spikes occur.

Part Context

The GBU8A-T belongs to the GBU-8 series of single-phase bridge rectifiers from Diotec Semiconductor. This series is characterized by its robust plastic housing and glass-passivated die, offering a cost-effective solution for medium-current rectification tasks. The 'T' suffix typically indicates reel packaging for automated assembly processes.

Replacement Considerations

Direct replacements must match the 8 A current rating, 50 V reverse voltage, and GBU (DO-201AB) footprint. Verify equivalent surge current ratings and forward voltage characteristics to ensure circuit compatibility without redesigning thermal or PCB layout constraints.
