GBJL1508-BP

Overview

The MCC GBJL1508-BP is a single-phase glass-passivated bridge rectifier rated for 15 A average forward current and an 800 V maximum repetitive peak reverse voltage. It features a 1.05 V maximum instantaneous forward voltage at 25°C and supports a 240 A peak forward surge current for half-sine wave pulses. The device operates within a junction temperature range of -55°C to +150°C, with a typical junction capacitance of 60 pF measured at 1.0 MHz. Packaged in the GBJL through-hole format, it utilizes epoxy compliant with UL 94 V-0 flammability ratings.

Feature Summary

• Glass passivation protects the junction against environmental stressors.
• Low forward voltage drop enables high current capability.
• Epoxy material meets UL 94 V-0 flammability rating.

Applications

• Printed circuit board mounting for AC-to-DC conversion.
• Power supply circuits requiring high surge current tolerance.
• Industrial equipment operating in extreme temperature environments.

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 traceability. Confirm that the ordering suffix matches the required specifications, noting that adding the "-HF" suffix designates halogen-free variants.

Selection Notes

Select this component when designs require a 15 A continuous current capacity paired with an 800 V blocking voltage. Ensure the application can accommodate the specified 240 A surge current during startup or fault conditions. Verify thermal management strategies align with the derating curves provided for case temperatures exceeding 100°C to maintain reliable operation.

Part Context

This part belongs to the GBJL series of single-phase bridge rectifiers manufactured by Micro Commercial Components. The series spans voltage ratings from 50 V to 1000 V while maintaining a consistent 15 A current rating. The GBJL1508 variant specifically addresses applications needing robust performance at 800 V reverse voltage levels.

Replacement Considerations

Direct substitutes include other GBJL series parts such as GBJL1506 or GBJL1510 if voltage requirements differ. Cross-brand replacements must match the 15 A current, 800 V rating, and GBJL package dimensions to ensure physical compatibility without PCB redesign.
