UR8KB100

Bridge Rectifier Overview

The UR8KB100 is a silicon planar fast recovery rectifier manufactured by Taiwan Semiconductor Corporation. It features an 800V maximum repetitive peak reverse voltage and an average forward rectified current of 8A. The device utilizes a DO-201AD (DO-4) axial-leaded package. Key electrical characteristics include a maximum non-repetitive peak surge forward current of 200A at 60Hz half-sine wave, a maximum RMS isolation voltage of 4000V, and a maximum DC blocking leakage current of 5μA at rated voltage. The component supports a junction temperature range from -55°C to +175°C.

Bridge Rectifier Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm exact specifications such as packaging type or lead finish. Ensure that the component meets all required regulatory standards for the intended application environment before finalizing procurement decisions.

Bridge Rectifier Selection Notes

Select this component based on its 800V reverse voltage rating and 8A continuous current capacity. Consider the thermal management requirements given the 175°C maximum junction temperature. Verify that the DO-201AD package fits the mechanical constraints of the target circuit board design.

Bridge Rectifier Part Context

This part belongs to the KB series of fast recovery rectifiers from Taiwan Semiconductor. These components are designed for general-purpose high-speed switching applications requiring robust performance in power supply circuits and motor control systems.

Bridge Rectifier Replacement Considerations

Direct replacements must match the 8A current rating, 800V reverse voltage, and DO-201AD package. Verify equivalent fast recovery times and forward voltage drops from other manufacturers offering similar axial-leaded rectifiers.
