KBU801G T0

Overview

The KBU801G T0 is a single-phase bridge rectifier manufactured by Taiwan Semiconductor Corporation, belonging to the KBU8 series. It features a molded plastic body in a KBU package with four terminals for through-hole mounting. The device supports a peak repetitive reverse voltage (Vrrm) of 50 V and an average forward rectified current (If) of 8 A at 25°C ambient temperature. It withstands a peak non-repetitive forward surge current (Ifsm) of 200 A under half-wave, 60 Hz, resistive or inductive load conditions. The component operates within a junction temperature range of -55°C to +150°C, with a maximum operating temperature of 150°C. Typical reverse leakage current (Ir) is less than 0.1 uA, and the peak forward voltage drop (Vf) is 1 V.

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm pinout configuration and electrical ratings. Ensure the green compound designation matches project requirements for environmental compliance. Confirm package dimensions and mounting torque specifications align with mechanical assembly constraints before finalizing procurement orders.

Selection Notes

Select this component when an 8 A continuous current rating and 50 V reverse voltage blocking capability are required. The KBU package offers robust mechanical stability for through-hole mounting. Consider the 200 A surge current rating for applications involving high inrush currents. Verify thermal management requirements to ensure junction temperatures remain within the specified -55°C to +150°C operational range during steady-state operation.

Part Context

This part belongs to the KBU8 series of single-phase bridge rectifiers from Taiwan Semiconductor. The series provides various voltage ratings while maintaining consistent 8 A current handling capabilities. The KBU package design facilitates automated insertion and wave soldering processes commonly used in high-volume electronics manufacturing environments.

Replacement Considerations

Cross-reference with other manufacturers offering KBU801 equivalents such as Won-Top Electronics or Fujitsu Electric. Verify that substitute components match the 8 A current rating, 50 V reverse voltage, and KBU package dimensions. Ensure terminal plating and solderability standards meet original equipment specifications.
