KBU3510-G

Overview

The KBU3510-G is a single-phase bridge rectifier manufactured by Comchip Technology, designed for through-hole mounting in the KBU-4 package. It features a peak repetitive reverse voltage of 1000 V and an average forward rectified current of 35 A. The device exhibits a maximum forward voltage drop of 1.1 V at 17.5 A and a reverse leakage current of 10 µA at 1000 V. It supports a non-repetitive peak forward surge current of 600 A and operates within a junction temperature range of -55°C to +150°C.

Feature Summary

• High thermal efficiency via integrated heat sink design
• Low forward voltage drop for improved system efficiency
• Robust surge current handling capability
• Compliant with RoHS directives

Applications

• General purpose AC to DC power supply conversion
• Battery charging circuits
• DC motor drive systems

Procurement Notes

Verify component authenticity against official Comchip Technology documentation. Confirm that the ordering suffix matches the required specifications. Ensure compliance with relevant environmental regulations such as RoHS before integration into final assemblies.

Selection Notes

Select this component when high current capacity and high voltage blocking are required in a compact through-hole form factor. Compare thermal resistance characteristics against alternative packages like KBPC or GBPC if board space constraints differ. Validate surge current ratings against specific application load profiles.
