GBU10A

Overview

The GBU10A is a single-phase silicon bridge rectifier manufactured by Diotec Semiconductor, rated for an average forward current of 10 A and a repetitive peak reverse voltage of 50 V. It utilizes the GBU-4 through-hole package with solder pin termination. The device supports a maximum junction temperature range from -50°C to +150°C. Typical thermal resistance values are 2.7 K/W (junction-to-case) and 18 K/W (junction-to-ambient). The component complies with RoHS standards and is designed for commercial and industrial applications.

Feature Summary

• Robust surge handling capability with a non-repetitive peak forward surge current rating of 200 A at 50 Hz.
• High thermal stability allowing operation up to a maximum junction temperature of +150°C.
• Compliant with environmental directives including RoHS and ELV standards.

Applications

• General-purpose AC to DC power supply rectification
• Industrial electronics control circuits
• Commercial equipment power stages

Procurement Notes

Verify the specific ordering suffix against official Diotec documentation to confirm exact electrical tolerances and packaging configurations. Ensure that the procurement channel provides valid traceability data and confirms compliance with current environmental regulations such as RoHS and REACH requirements before finalizing orders.

Selection Notes

Select this component when a 10 A continuous current rating and 50 V blocking voltage are required in a standard GBU-4 through-hole footprint. Evaluate the thermal resistance parameters against the system's heat dissipation capabilities to ensure the junction temperature remains within the specified operational limits during steady-state and transient conditions.

Part Context

This part belongs to the GBU10 series of single-phase bridge rectifiers produced by Diotec Semiconductor. The series covers various voltage ratings from 50 V to 1000 V while maintaining a consistent 10 A current capacity and physical package dimensions. This specific model represents the lowest voltage option within the standardized GBU10 lineup.

Replacement Considerations

Cross-reference with other manufacturers offering GBU-4 packaged 10 A bridge rectifiers rated at 50 V or higher. Verify that substitute components match the forward voltage characteristics and thermal resistance specifications to maintain circuit performance integrity.
