UR2KB80

Bridge Rectifier Overview

The UR2KB80 is a single-phase bridge rectifier manufactured by Taiwan Semiconductor Corporation. It features a peak repetitive reverse voltage (Vrrm) of 800 V and an average forward rectified current (Io) of 2 A. The device utilizes the D3K-4 through-hole package with four pins. Key electrical characteristics include a maximum non-repetitive peak forward surge current (Ifsm) of 50 A, a maximum RMS reverse voltage of 560 V, and a maximum DC blocking voltage of 800 V. Thermal performance is defined by a maximum operating junction temperature of 150°C and a storage temperature range from -55°C to +150°C. The component exhibits a maximum RMS current rating of 6.3 A.

Bridge Rectifier Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm exact packaging and marking configurations. Ensure that any selected variant matches the required thermal and electrical specifications for the target application environment. Cross-reference part numbers with authorized distributors to confirm availability and authenticity before procurement.

Bridge Rectifier Selection Notes

Select this component when a 2 A current rating and 800 V voltage capability are required in a compact through-hole format. Evaluate the thermal resistance and mounting constraints associated with the D3K-4 package. Confirm that the circuit's surge current demands remain within the specified 50 A limit during transient events.

Bridge Rectifier Part Context

This component belongs to the UR series of glass-passivated bridge rectifiers designed for general-purpose applications. The series offers various current and voltage ratings within standardized packages to facilitate design flexibility. The UR2KB80 specifically addresses needs for moderate current handling with high voltage blocking capabilities in industrial and consumer electronics.

Bridge Rectifier Replacement Considerations

Direct replacements must match the 2 A current rating, 800 V reverse voltage, and D3K-4 package footprint. Verify pinout compatibility and thermal characteristics. Consult manufacturer cross-reference lists for equivalent parts from other suppliers offering identical electrical and mechanical specifications.
