GBJL2508-BP

Overview

The MCC GBJL2508-BP is a glass passivated single-phase bridge rectifier rated for 25 A average forward current and an 800 V maximum repetitive peak reverse voltage. It features a low instantaneous forward voltage drop of 1.05 V at 12.5 A and a maximum DC reverse leakage current of 10 µA at 500 V. The device withstands a 350 A peak forward surge current and operates within a junction temperature range of -55°C to +150°C. Packaged in the GBJL through-hole format, it utilizes molded epoxy meeting UL 94 V-0 flammability standards.

Feature Summary

• Glass passivation provides stable electrical characteristics and protects against mechanical stress.
• Low forward voltage drop design enhances efficiency and reduces power dissipation.
• High surge overload capability supports transient load conditions.
• Epoxy case meets UL 94 V-0 flammability rating for safety compliance.

Applications

• Printed circuit board mounting for AC-to-DC conversion
• Power supply rectification in industrial equipment
• General purpose high-current rectification circuits

Procurement Notes

Verify component authenticity by purchasing exclusively from Micro Commercial Components or their authorized distributors. Counterfeit parts pose significant risks; unauthorized sources do not provide warranty coverage or quality assurance. Confirm RoHS compliance via the standard suffix and check for halogen-free availability if required by specific environmental regulations.

Selection Notes

Select this component when a 25 A continuous current rating and 800 V blocking voltage are required in a compact through-hole package. Ensure thermal management aligns with the derating curve for case temperatures above 100°C. Verify that the 350 A surge rating exceeds the application's peak inrush currents to prevent device failure during startup.

Part Context

This part belongs to the GBJL series of 25 Amp glass passivated bridge rectifiers manufactured by Micro Commercial Components. The series spans voltage ratings from 50 V to 1000 V, sharing identical physical dimensions and thermal characteristics. The GBJL2508-BP specifically addresses applications requiring 800 V isolation while maintaining the standard GBJL footprint.

Replacement Considerations

Cross-reference with other manufacturers offering GBJL-style packages. Verify that substitute components match the 25 A current rating, 800 V reverse voltage, and 1.05 V forward voltage drop. Ensure pinout compatibility and thermal resistance values are equivalent to maintain circuit performance.

FAQ

What is the maximum non-repetitive surge current rating?

The GBJL2508-BP can withstand a peak forward surge current of 350 A for an 8.3 ms half sine-wave pulse.

How does the forward current change with case temperature?

The average forward current must be derated as the case temperature increases beyond 100°C, following the manufacturer's derating curve.

Is the device compliant with RoHS standards?

Yes, the standard ordering suffix indicates the product is lead-free and RoHS compliant.
