Overview
The KBU803G is a single-phase bridge rectifier manufactured by Taiwan Semiconductor, belonging to the KBU8 series. It utilizes a KBU plastic package with four pins for through-hole mounting. The device features a peak repetitive reverse voltage (Vrrm) of 200 V and an average forward rectified current (If) of 8 A. It supports a peak non-repetitive forward surge current (Ifsm) of 200 A. The component operates within a temperature range of -55°C to +150°C. Key electrical characteristics include a maximum forward voltage drop (Vf) of 1 V and a peak reverse leakage current (Ir) of 5 μA. Physical dimensions are approximately 23.7 mm in length and 19.3 mm in height.
Feature Summary
- High thermal stability allowing operation up to 150°C
- Robust surge current handling capability
- Low forward voltage drop for improved efficiency
- Isolated flange mount design
Applications
- AC-DC power supply circuits
- Battery charging systems
- General-purpose rectification in industrial equipment
Procurement Notes
Verify the manufacturer part number KBU803G against official Taiwan Semiconductor documentation to confirm specifications. Ensure the ordering suffix matches the required packaging and compliance standards. Cross-reference datasheet parameters such as Vrrm and If with system requirements before procurement.
Selection Notes
Select this component when a 200 V rating and 8 A continuous current are required in a KBU package. Consider the 200 A surge capacity for inductive loads. Verify that the 150°C junction temperature rating suits the thermal environment. Compare physical dimensions against available PCB space.
Part Context
The KBU803G is part of the KBU8 series from Taiwan Semiconductor, designed for general-purpose bridge rectification. This series offers high current density in a compact KBU package. It serves as a standard solution for converting AC to DC in various electronic applications requiring reliable performance under moderate voltage and current conditions.
Replacement Considerations
Direct substitutes must match the 200 V Vrrm, 8 A If, and KBU package. Check equivalent parts from other manufacturers for identical pinout and thermal characteristics. Verify that alternative components meet the same Ifsm and Vf specifications.
