KBU1006G

Overview

The KBU1006G is a single-phase bridge rectifier manufactured by Taiwan Semiconductor Corporation. It utilizes the KBU through-hole package with four pins and provides a peak repetitive reverse voltage (Vrrm) of 800 V. The device supports a maximum average forward rectified current (If) of 10 A and withstands a peak non-repetitive forward surge current (Ifsm) of 200 A. Electrical characteristics include a maximum forward voltage drop (Vf) of 1.1 V and a peak reverse leakage current (Ir) of 5 μA. The component operates within a junction temperature range from -55°C to +150°C, with physical dimensions measuring 23.7 mm in length, 7.1 mm in width, and 19.3 mm in height.

Feature Summary

• High thermal stability enabling operation up to 150°C
• Robust surge current handling capability for transient protection
• Low forward voltage drop for improved efficiency
• Through-hole mounting for secure PCB integration

Applications

• AC-DC power supply circuits
• Battery charging systems
• General-purpose rectification in industrial equipment

Procurement Notes

Verify part authenticity by checking manufacturer markings against official datasheets. Confirm package type and pin configuration match design requirements. Ensure storage conditions comply with moisture sensitivity levels. Validate supplier authorization status before purchase. Cross-reference ordering suffixes to confirm specific tape-and-reel or tray packaging variations if applicable.

Selection Notes

Select this component when an 800 V reverse voltage rating is required for single-phase rectification. The 10 A continuous current capacity suits moderate power applications. Consider the KBU package size for available board space. Verify thermal management needs given the 150°C maximum junction temperature limit. Compare alternative voltages within the KBU100 series if system requirements differ.

Part Context

The KBU1006G belongs to the KBU100 series of single-phase bridge rectifiers from Taiwan Semiconductor. This series offers various voltage ratings while maintaining consistent 10 A current handling and KBU package dimensions. The '100' designation typically indicates the 10 A current class, while the suffix '6' denotes the 800 V blocking voltage variant within the lineup.

Replacement Considerations

Direct substitutes may include other KBU100 series variants with identical current ratings but different voltage ratings, such as KBU1004G (400 V) or KBU1005G (600 V), provided the circuit voltage does not exceed their limits. Generic replacements must match the 10 A If, 800 V Vrrm, and KBU-4 package footprint.
