GBJ3504-BP

Overview

The GBJ3504-BP is a single-phase bridge rectifier manufactured by Micro Commercial Components (MCC). It features an average forward current of 35 A and a repetitive peak reverse voltage of 400 V. The device utilizes a glass passivated junction construction for enhanced stability. Key electrical parameters include a maximum forward voltage drop of 1.1 V at rated current and a non-repetitive peak forward surge current capability of 400 A. The component operates within a temperature range from -55°C to +150°C. It is housed in a GBPC-W-4 package with solder pin termination, designed for through-hole mounting on printed circuit boards.

Feature Summary

• Glass passivated junction construction provides mechanical strength and stability against thermal cycling.
• High current capability with low forward voltage drop for efficient power conversion.
• Robust surge overload protection handles high transient currents during startup or fault conditions.

Applications

• AC-DC power supply circuits requiring 35A current handling.
• Battery chargers and DC power adapters.
• General-purpose rectification in industrial equipment.

Procurement Notes

Verify the specific suffix "BP" indicates RoHS compliance as per MCC documentation. Confirm the package type matches the required PCB footprint, as variations exist within the GBPC series. Check for obsolescence status, as some MCC bridge rectifiers may be marked as Not Recommended for New Designs (NRND) depending on the production batch. Ensure the supplier provides valid datasheets confirming the 400V rating and 35A continuous current specifications before finalizing orders.

Selection Notes

Select this component when a 35A single-phase bridge rectifier with a 400V blocking voltage is required. Compare the 1.1V forward voltage drop against alternative packages like KBPC or GBJ to assess thermal management needs. Ensure the through-hole GBPC-W-4 package fits the mechanical constraints of the enclosure. Verify that the 400A surge current rating exceeds the expected inrush current of the load application.

Part Context

The GBJ3504-BP belongs to the MCC GBPC series of silicon bridge rectifiers. This series is characterized by high current density and compact packaging relative to performance. The "GBPC" designation typically refers to the specific plastic encapsulated case style with four terminals. Other variants in the family offer different voltage ratings such as 600V or 800V while maintaining the same 35A current capacity.

Replacement Considerations

Direct substitutes include Vishay VS-GBPC3504A and Rectron RGP3504, which share identical 35A/400V ratings and GBPC package dimensions. Ensure any replacement maintains the same forward voltage characteristics and thermal resistance values to avoid redesigning heat sinking solutions.
