PB34-BP

Bridge Rectifier Overview

The PB34-BP is a single-phase bridge rectifier manufactured by Micro Commercial Components (MCC). It features an average forward current rating of 3.0 A and a maximum repetitive peak reverse voltage of 400 V. The device utilizes a BR-6 package with solder pin termination for through-hole mounting. Key electrical characteristics include a maximum non-repetitive surge current of 150 A at 60 Hz, a maximum RMS input voltage of 280 V, and a typical forward voltage drop of 1.1 V. The component operates within a junction temperature range of -55°C to +150°C.

Bridge Rectifier Procurement Notes

Verify the specific datasheet version for the PB34-BP to confirm RoHS compliance status and exact mechanical dimensions. Ensure the BR-6 footprint matches the target PCB layout. Confirm that the 3A current rating and 400V voltage withstand requirements align with the design specifications before finalizing procurement.

Bridge Rectifier Selection Notes

Select this component when a 3A continuous current and 400V blocking voltage are required in a through-hole bridge rectifier format. Compare the 1.1V forward voltage drop against efficiency requirements. Verify that the BR-6 package size fits the available board space and that the lead pitch accommodates the assembly process.

Bridge Rectifier Part Context

The PB34-BP belongs to MCC's PB series of single-phase bridge rectifiers, which typically cover current ratings from 1A to 10A and voltage ratings from 50V to 1000V. This specific model represents the 3A/400V variant within the BR-6 package family, designed for general industrial and consumer electronics applications requiring reliable AC-to-DC conversion.

Bridge Rectifier Replacement Considerations

Cross-reference with other 3A/400V bridge rectifiers in the BR-6 package, such as those from Vishay or Littelfuse. Verify pinout compatibility and mechanical dimensions before substitution. Ensure equivalent thermal and electrical ratings are maintained.
