KBU406G T0G

Overview

The KBU406G T0G is a single-phase silicon bridge rectifier manufactured by Taiwan Semiconductor Corporation. It features a maximum average forward rectified current of 4 A and a maximum repetitive peak reverse voltage of 600 V. The device utilizes glass passivated junctions for enhanced reliability and operates within a junction temperature range of -55°C to +150°C. Electrical characteristics include a typical instantaneous forward voltage of 1.1 V at 4 A and a maximum DC reverse current of 500 μA at 125°C. The component is housed in a KBU plastic package with matte tin-plated leads, suitable for printed circuit board mounting.

Procurement Notes

Verify the specific ordering suffix to confirm packaging details. The 'T0' code indicates tray packing, while the 'G' suffix denotes the use of green halogen-free compound. Confirm that the selected variant matches the required mechanical dimensions and thermal resistance values for the intended application design.

Selection Notes

Select this component based on the 600 V reverse voltage requirement and 4 A continuous current rating. Ensure the operating environment stays within the specified -55°C to +150°C junction temperature limits. Consider the thermal resistance values when designing heatsinking or airflow requirements for high ambient temperatures.

Part Context

This part belongs to the KBU40xG series of glass passivated bridge rectifiers from Taiwan Semiconductor. The series covers voltage ratings from 50 V to 1000 V, all sharing the same 4 A current capability and KBU package form factor. The KBU406G specifically addresses applications requiring 600 V blocking capability.

Replacement Considerations

Compatible substitutes within the same series include KBU408G (800 V) and KBU404G (400 V), provided the voltage rating meets the circuit requirements. Other manufacturers offering equivalent 4 A, 600 V bridge rectifiers in the KBU package may be considered if mechanical and electrical specifications align.
