GBU4005-G

Overview

The GBU4005-G is a single-phase bridge rectifier manufactured by Comchip Technology. It utilizes glass passivated die construction for enhanced reliability and features a GBU plastic case with UL flammability classification rating 94V-0. The device supports an average forward rectified current of 4.0 A and offers a peak repetitive reverse voltage of 600 V. Key electrical characteristics include a maximum non-repetitive peak forward surge current of 150 A at 60 Hz and a low reverse leakage current. The component is designed for through-hole mounting on printed circuit boards, complies with RoHS standards, and provides high case dielectric strength.

Feature Summary

• Glass passivated die construction ensures high reliability and stable performance under varying conditions.
• High case dielectric strength of 1500 Vrms provides robust insulation and safety margins.
• Surge overload rating accommodates transient currents up to 150 A peak for circuit protection.
• Low reverse leakage current minimizes power loss and heat generation during operation.

Applications

• Printed circuit board applications requiring compact rectification solutions
• General-purpose AC to DC conversion in power supply units
• Industrial equipment utilizing through-hole mounting constraints

Procurement Notes

Verify the specific ordering suffix against official Comchip Technology documentation to confirm exact mechanical dimensions and plating specifications. Ensure that the selected variant matches the required thermal management capabilities for the intended operating environment. Cross-reference the datasheet revision date to guarantee alignment with current manufacturing standards and compliance certifications.

Selection Notes

Select this component when a 4.0 A continuous current rating and 600 V blocking voltage are required within a GBU package. Consider the 150 A surge capability for circuits experiencing significant inrush currents. Evaluate the through-hole mounting style against available PCB layout space and assembly methods. Confirm compatibility with lead-free soldering processes if RoHS compliance is mandatory for the final product.

Part Context

The GBU4005-G belongs to the GBU series of single-phase bridge rectifiers from Comchip Technology. This series is characterized by its molded plastic case material and glass passivated junctions. The GBU form factor is widely recognized for its balance of current handling capacity and physical footprint, making it suitable for various consumer and industrial electronics applications requiring reliable rectification.

Replacement Considerations

Direct substitutes must match the 4.0 A current rating, 600 V reverse voltage, and GBU package outline. Verify pinout compatibility and thermal resistance values before implementation. Alternative manufacturers producing equivalent glass-passivated bridge rectifiers in the GBU format may be considered if they meet the same electrical and mechanical specifications.
