GBU406

Overview

The MDD GBU406 is a single-phase glass passivated bridge rectifier designed for through-hole mounting. It features a molded plastic body with a maximum average forward rectified current of 4.0 A and a repetitive peak reverse voltage of 600 V. The device supports a peak forward surge current of 150 A under JEDEC testing conditions. Electrical characteristics include a maximum forward voltage of 1.1 V at 2.0 A DC and a reverse leakage current of 10 µA at 25°C. Operating junction temperatures range from -55°C to +150°C, with a thermal resistance of 2.2 °C/W.

Feature Summary

• Glass passivated die construction ensures reliable low-cost performance.
• Molded plastic case meets UL flammability classification 94V-0.
• Suitable for printed circuit board applications.

Applications

• Printed circuit board power supply circuits
• General-purpose AC to DC conversion
• Industrial control systems

Procurement Notes

Verify the original manufacturer designation as MDD against the specific part code GBU0406000L460 found in the provided specification sheet. Confirm that the component matches the GBU series physical dimensions and terminal configuration required for your assembly. Ensure compliance with RoHS standards if applicable to your manufacturing process.

Selection Notes

Select this component when a 4 A current rating and 600 V blocking voltage are required for through-hole PCB mounting. Consider the 150 A surge capability for inrush protection needs. Verify that the operating temperature range of -55°C to +150°C aligns with your environmental specifications.

Part Context

This component belongs to the GBU series of single-phase bridge rectifiers manufactured by MDD. The series includes variants with different voltage ratings while maintaining the same 4 A current capacity and GBU package form factor. It is designed as a general-purpose replacement for standard bridge rectifier applications.

Replacement Considerations

Cross-reference part numbers such as GBU406 from other manufacturers like Comchip or LGE may be compatible if electrical parameters match exactly. Verify pinout orientation and physical dimensions before substitution.
