GBU8M-T

Overview

The GBU8M-T is a single-phase bridge rectifier manufactured by Diotec Semiconductor, designed for high-efficiency AC-to-DC conversion in power supply applications. It features an 8 A average forward current rating and supports a maximum repetitive peak reverse voltage of 1000 V. The device utilizes glass passivation for junction protection and is housed in the GBU package, which facilitates through-hole mounting with solder pins. It operates reliably within a junction temperature range of -55 °C to +150 °C and exhibits a low forward voltage drop of approximately 1.1 V at rated current. The component complies with RoHS directives and is free from halogenated substances.

Feature Summary

• Glass passivated junctions provide robust protection against mechanical stress and environmental factors.
• High surge current capability ensures reliable operation during transient load conditions.
• Low forward voltage drop minimizes power dissipation and improves overall energy efficiency.
• Designed for high reliability with no internal polymer materials present.

Applications

• AC/DC power supplies
• Battery chargers
• Inverter circuits

Procurement Notes

Verify the specific ordering suffix to confirm the tape-and-reel packaging configuration, as standard bulk quantities may differ. Ensure that the procurement documentation explicitly states compliance with RoHS and REACH regulations. Confirm the manufacturer part number matches the exact electrical ratings required for the target circuit design before finalizing orders.

Selection Notes

Select this component when a single-phase bridge rectifier with an 8 A current capacity and 1000 V blocking voltage is required. The GBU package offers a compact footprint suitable for various industrial enclosures. Consider the thermal management requirements based on the specified forward voltage drop and ambient operating temperatures to ensure long-term stability.

Part Context

This component belongs to Diotec's GBU series of single-phase bridge rectifiers, which are widely used in general-purpose power conversion. The series is characterized by its glass passivation technology and high surge current handling. The GBU8M-T specifically addresses applications requiring moderate current levels with high voltage isolation capabilities.

Replacement Considerations

Compatible substitutes include the GBU8K (600 V rating) if voltage requirements allow, or other 8 A bridge rectifiers in the GBU package such as those from Panasonic or Vishay. Verify pinout compatibility and thermal characteristics before substitution.
