Overview
The KBU403G T0G is a glass passivated bridge rectifier manufactured by Taiwan Semiconductor. It provides a maximum average forward rectified current of 4A and a maximum repetitive peak reverse voltage of 200V. The device features a typical instantaneous forward voltage of 1.1V at 4A and a peak forward surge current capability of 150A for an 8.3ms half-sine wave. Operating junction temperature ranges from -55°C to +150°C, with storage temperatures spanning the same range. The component utilizes a 7.2g case with matte tin-plated leads and meets JESD 201 class 1A whisker test requirements.
Feature Summary
- Glass passivated junction construction
- High case dielectric strength
- Halogen-free molding compound

Procurement Notes
Verify the specific ordering suffix against official documentation to confirm packing code details. Confirm compliance with RoHS Directive 2011/65/EU and WEEE 2002/96/EC standards prior to integration. Ensure thermal management aligns with the specified derating curves for the intended ambient conditions.
Selection Notes
Select this component based on the required 200V reverse voltage rating and 4A continuous current capacity. Evaluate thermal resistance parameters against the expected operating environment to ensure junction temperatures remain within the specified limits during peak load conditions.
Part Context
This part belongs to the KBU40xG series of glass passivated bridge rectifiers from Taiwan Semiconductor. The series covers voltage ratings from 50V to 1000V, sharing common mechanical and electrical characteristics while differing primarily in their peak reverse voltage specifications.
Replacement Considerations
Cross-reference with other 4A bridge rectifiers offering similar 200V ratings and compatible package dimensions. Verify that substitute components meet the same thermal resistance and surge current requirements.
