Overview
The GBU405 is a single-phase standard bridge rectifier manufactured by Taiwan Semiconductor Corporation. It features a 600V peak repetitive reverse voltage rating and supports a maximum average forward rectified current of 4A. The device utilizes a GBU surface-mount package with four pins for through-hole installation. Key electrical specifications include a peak non-repetitive forward surge current of 280A, a maximum forward voltage drop of 1.1V at rated current, and a peak reverse leakage current of 500µA. The component operates within a junction temperature range of -55°C to +150°C.
Feature Summary
- Glass-passivated silicon construction ensures reliable operation under high-temperature conditions.
- Plastic encapsulate material meets Underwriters Laboratories flammability classification 94V-0 standards.
- High case dielectric strength provides robust insulation performance.
Applications
- Printed circuit board power supply designs
- General-purpose AC to DC conversion circuits
- Industrial equipment requiring standard rectification
Procurement Notes
Verify the specific suffix designation when ordering, as variants such as GBU405-K exist within the product line. Confirm RoHS compliance status and packaging type directly with the manufacturer or authorized distributors prior to purchase. Ensure that the selected part number matches the required voltage and current ratings for the intended application to avoid compatibility issues.
Selection Notes
Select this component for applications requiring a 600V blocking capability and 4A continuous current handling in a compact GBU footprint. Consider the thermal management requirements given the 150°C maximum junction temperature limit. Evaluate the 1.1V forward voltage drop impact on system efficiency during high-load operations compared to alternative rectifier technologies.
Part Context
The GBU405 belongs to the GBU4 series of single-phase bridge rectifiers from Taiwan Semiconductor. This series offers various voltage ratings ranging from 400V to 1000V while maintaining a consistent 4A current capacity and GBU package form factor. The GBU405 specifically addresses mid-range voltage applications within this standardized family.
Replacement Considerations
Direct substitutes within the same series include GBU406 (800V) and GBU407 (1000V) if higher voltage margins are needed. Other manufacturers offering equivalent 4A/600V GBU packages should be evaluated based on matching electrical parameters and physical dimensions.
