UR3KB100

Bridge Rectifier Overview

The UR3KB100 is a standard bridge rectifier manufactured by Taiwan Semiconductor. It features a maximum average forward rectified current of 3A and a repetitive peak reverse voltage of 1000V. The device utilizes a D3K package, which is a molded plastic case designed for robust mechanical stability. Electrical characteristics include a maximum non-repetitive peak forward surge current capability and a low forward voltage drop to ensure efficient power conversion. The component is compliant with RoHS directives and is halogen-free, meeting environmental standards for modern electronic assemblies.

Bridge Rectifier Procurement Notes

Verify availability status directly with the manufacturer or authorized distributors, as supply constraints may exist. Confirm the specific ordering suffix matches the required packaging type, such as tube quantities. Ensure the component meets the necessary environmental compliance certifications for the target market before finalizing procurement orders.

Bridge Rectifier Selection Notes

Select this component when a 3A current rating and 1000V blocking voltage are required in a compact bridge format. The D3K package offers a balance between thermal performance and board space efficiency. Consider the forward voltage drop and thermal resistance characteristics relative to the expected ambient operating conditions and heat dissipation capabilities of the final assembly.

Bridge Rectifier Part Context

This part belongs to the UR3KB series of bridge rectifiers from Taiwan Semiconductor. The series provides various voltage ratings while maintaining a consistent 3A current capacity and D3K package style. This family is designed for general-purpose applications requiring reliable rectification in industrial and consumer electronics.

Bridge Rectifier Replacement Considerations

Direct replacements must match the 3A current rating, 1000V reverse voltage, and D3K package dimensions. Verify that alternative bridge rectifiers offer comparable forward voltage drops and surge current capabilities to ensure circuit performance parity.
