Bridge Rectifier datasheet and documents for UD8KB05-BP
Bridge Rectifier Overview
The MCC UD8KB05-BP is a single-phase glass passivated bridge rectifier rated for an average forward current of 8 A at a case temperature of 140°C. It supports peak repetitive reverse voltages from 50 V to 1000 V, with the specific model providing a 50 V rating. The device features a maximum non-repetitive peak surge current of 175 A under an 8.3 ms half-sine wave condition and includes an I2t fusing rating of 127.1 A²s. Electrical characteristics include a typical forward voltage drop of 0.95 V at 4 A and a junction-to-case thermal resistance of 1.5 °C/W. The component operates within a junction temperature range of -55°C to 150°C.

Bridge Rectifier Procurement Notes
Verify authenticity by purchasing directly from Micro Commercial Components or authorized distributors. Counterfeit parts are prevalent; unauthorized sources lack traceability and warranty coverage. Confirm the BP suffix indicates RoHS compliance and lead-free finish before procurement.
Bridge Rectifier Selection Notes
Select this component based on the required reverse voltage rating (50 V) and the 8 A continuous current capacity at elevated case temperatures. Ensure adequate heatsinking to maintain the junction temperature within the specified operating range, considering the thermal resistance values provided in the datasheet.
Bridge Rectifier Part Context
This part belongs to the UD8KB series of bridge rectifiers manufactured by Micro Commercial Components. The series covers various voltage ratings from 50 V to 1000 V while maintaining a consistent 8 A current rating and D3K package form factor.
Bridge Rectifier Replacement Considerations
Other models in the UD8KB series (e.g., UD8KB10-BP through UD8KB100-BP) share identical mechanical and current specifications but differ in peak repetitive reverse voltage ratings. Verify voltage compatibility when substituting.
Bridge Rectifier FAQ
