GBU10M

Overview

The GBU10M is a single-phase bridge rectifier manufactured by Diotec Semiconductor, rated for a maximum average forward rectified current (IFAV) of 10 A and a repetitive peak reverse voltage (VRRM) of 1000 V. The device utilizes a molded plastic GBU package with solder pin through-hole mounting. It supports a peak forward surge current (IFSM) of 220 A under 60 Hz half-sine-wave conditions and operates within a junction temperature range of -50°C to +150°C. Typical thermal resistance values are 18 K/W from junction to ambient and 2.7 K/W from junction to case.

Feature Summary

• High surge current capability with an IFSM rating of 220 A
• Robust thermal performance with low junction-to-case thermal resistance
• Designed for high-voltage applications up to 1000 V reverse blocking
• Compliant with RoHS standards and ELV directive

Applications

• General-purpose AC-DC power supply rectification
• Industrial electronics control systems
• White goods and home appliance power circuits
• Battery charging equipment input stages

Procurement Notes

Verify the specific ordering suffix against official Diotec documentation to confirm the exact voltage rating, as the GBU10 series includes variants such as GBU10A through GBU10M. Confirm that the required surge current protection aligns with the datasheet's recommended protective resistance calculations. Ensure compliance with commercial or industrial grade reliability requirements before finalizing procurement specifications.

Selection Notes

Select the GBU10M when a 1000 V reverse voltage rating is necessary for the application circuit. Evaluate the thermal management strategy based on the specified junction-to-ambient thermal resistance of 18 K/W. Consider the 220 A surge current capacity relative to the expected inrush currents during startup. Verify that the through-hole GBU package dimensions fit the target PCB layout constraints.

Part Context

The GBU10M belongs to the GBU10A...GBU10M family of single-phase bridge rectifiers produced by Diotec Semiconductor. This series covers various peak reverse voltage ratings from 50 V to 1000 V while maintaining a consistent 10 A forward current rating and GBU package outline. The components are designed for standard commercial and industrial applications requiring reliable silicon rectification.

Replacement Considerations

Cross-reference alternative manufacturers offering GBU-style bridge rectifiers with identical 10 A current and 1000 V voltage ratings. Verify mechanical footprint compatibility and pinout configuration before substitution. Ensure equivalent thermal resistance and surge current capabilities match the original design requirements.
