Overview
The KBU604G is a single-phase bridge rectifier manufactured by Taiwan Semiconductor. It features glass passivated junctions and utilizes the KBU-4 through-hole package. The device supports a maximum average forward rectified current of 6.0 A at a case temperature of 75°C. Its peak repetitive reverse voltage rating is 400 V, with a corresponding maximum non-repetitive peak forward surge current capability of 175 A at 8.3 ms half-sine wave. The component operates within an ambient temperature range from -55°C to +150°C.
Feature Summary
- Glass passivated junctions provide high reliability and stability under varying thermal conditions.
- High surge current capability ensures robust performance during transient electrical events.
- Molded case meets UL flammability classification rating 94V-0 for enhanced safety.
Applications
- Printed circuit board mounting in power supply units
- AC-to-DC conversion circuits
- General-purpose rectification in industrial electronics
Procurement Notes
Verify the manufacturer datasheet to confirm exact electrical ratings and mechanical dimensions before integration. Ensure the ordering suffix matches the required halogen-free green compound specification. Cross-reference the specific revision level to guarantee compliance with RoHS directives and WEEE standards applicable to your region.
Selection Notes
Select this component when a 6.0 A continuous current rating and 400 V reverse voltage blocking are required. The KBU-4 package is suitable for through-hole PCB assembly where moderate current handling is necessary. Consider thermal management requirements as the device dissipates heat based on the forward voltage drop at rated load currents.
Part Context
This part belongs to the KBU series of single-phase bridge rectifiers produced by Taiwan Semiconductor. The series covers various current ratings from 2.0 A to 8.0 A and voltage ratings up to 1000 V. The 'G' suffix typically denotes the halogen-free variant compliant with IEC 61249-2-21 definitions.
Replacement Considerations
Compatible substitutes include the KBU604 from other manufacturers offering identical 6.0 A and 400 V specifications in the KBU-4 package. Verify pinout compatibility and thermal characteristics when replacing.
