GBJA2508-BP

Overview

The MCC GBJA2508-BP is a single-phase glass passivated bridge rectifier rated for 25 A average forward current and 800 V peak repetitive reverse voltage. It utilizes a JA-4 through-hole package with solder pin termination. Key electrical parameters include a maximum forward voltage of 1.05 V at 12.5 A, a non-repetitive peak surge current of 350 A (8.3 ms half sine wave), and a reverse leakage current of 5 µA at 25°C. The device 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 meets UL 94 V-0 flammability rating

Applications

• General purpose AC to DC power supply rectification
• Battery charging circuits
• DC motor drive input stages

Procurement Notes

Verify authenticity by purchasing directly from Micro Commercial Components or authorized distributors. Counterfeit components are prevalent; unauthorized sources lack traceability and warranty coverage. Confirm the BP suffix indicates RoHS compliance and lead-free finish before ordering.

Selection Notes

Select this component when an 800 V blocking voltage and 25 A continuous current capacity are required in a compact through-hole form factor. Ensure thermal management accommodates the 22 °C/W junction-to-ambient resistance if heatsinking is not utilized. Verify that the 350 A surge rating exceeds expected inrush currents.

Part Context

This part belongs to the GBJA series of high-current bridge rectifiers manufactured by Micro Commercial Components. The series spans ratings from 50 V to 1000 V reverse voltage while maintaining a consistent 25 A current rating and JA-4 package style across variants.

Replacement Considerations

Cross-reference with other manufacturers' GBJ-style 25 A / 800 V bridge rectifiers such as those from Diodes Incorporated or Taitron. Verify pinout compatibility and physical dimensions match the JA-4 footprint before substitution.
