GBU2504-BP

Overview

The GBU2504-BP is a single-phase bridge rectifier manufactured by Micro Commercial Components (MCC). It features a 25 A average rectified forward current and a 400 V peak repetitive reverse voltage. The device utilizes glass passivated chip junctions for reliability. Electrical characteristics include a maximum forward voltage of 1.0 V at 12.5 A, a typical reverse leakage current of 5 uA at 25°C, and a non-repetitive peak surge current capability of 350 A for an 8.3 ms half-sine wave. The component operates within a junction temperature range of -55°C to +150°C.

Feature Summary

• Glass passivated chip junction construction
• High surge forward current capability
• Epoxy material meets UL 94 V-0 flammability rating

Applications

• General purpose single phase bridge rectification
• Switching mode power supplies (SMPS)
• Adapters
• Television sets
• Computer monitors

Procurement Notes

Verify authenticity through authorized MCC distributors or direct purchase from the manufacturer. Counterfeit components are prevalent in the market; unauthorized sources do not provide warranty coverage or traceability. Confirm RoHS compliance status via the "BP" suffix designation on official documentation before procurement.

Selection Notes

Select this component for applications requiring a 25 A continuous current rating with a 400 V blocking voltage. Ensure thermal management aligns with the specified Rth(J-A) of 25 °C/W without a heatsink or Rth(J-C) of 1 °C/W with a heatsink. Verify that the operating environment remains within the -55°C to +150°C junction temperature limits.

Part Context

This part belongs to the GBU25005 through GBU2510 series of 25 Amp bridge rectifiers. The series offers varying reverse voltage ratings from 50 V to 1000 V while maintaining identical current handling and physical dimensions. The GBU2504 specifically targets 400 V AC input applications.

Replacement Considerations

Direct replacements must match the GBU package footprint and 25 A / 400 V specifications. Other manufacturers offering glass-passivated silicon bridge rectifiers in the GBU form factor may serve as substitutes if electrical parameters meet or exceed the original requirements.
