Overview
The KBU402G T0 is a single-phase bridge rectifier manufactured by Taiwan Semiconductor Corporation. It utilizes glass passivated die technology for enhanced reverse voltage blocking capability and stability under harsh conditions. The device features a plastic encapsulated KBU package designed for through-hole mounting on printed circuit boards. Key electrical parameters include a maximum average forward rectified current of 4 A and a repetitive peak reverse voltage rating of 200 V. The component supports a maximum non-repetitive peak surge current of 150 A and operates within a junction temperature range of -55 °C to +150 °C.
Feature Summary
- Glass passivated junctions provide high reliability and stable performance in demanding environments.
- Plastic encapsulation offers mechanical protection and compliance with standard mounting requirements.
Applications
- General-purpose AC to DC power supply circuits
- Battery charging systems
- DC motor drive rectification
Procurement Notes
Verify the specific suffix 'T0' against official datasheets to confirm reel packaging or tape-and-reel specifications, as this may differ from bulk variants. Ensure the manufacturer is confirmed as Taiwan Semiconductor Corporation to avoid confusion with similar part numbers from other vendors. Cross-reference the full part number with authorized distributors to validate current availability and authenticity before procurement.
Selection Notes
Select this component when a 4 A single-phase rectification solution with a 200 V reverse voltage rating is required. The KBU package is suitable for applications needing robust thermal dissipation and secure through-hole attachment. Consider the operating temperature range and surge current capabilities to ensure compatibility with the specific circuit load profiles and environmental conditions.
Part Context
This component belongs to the KBU series of single-phase bridge rectifiers from Taiwan Semiconductor. The series typically includes variants with different voltage ratings while maintaining the same 4 A current capacity and physical footprint. The KBU package provides a standardized form factor for easy integration into various power electronics designs requiring reliable rectification.
Replacement Considerations
Compatible substitutes include the KBU402G from other manufacturers such as HY Electronic, provided the electrical ratings and pinout configuration match exactly. Verify that alternative components also feature glass passivation and compatible package dimensions to ensure seamless replacement without PCB redesign.
