GBJ30M

Overview

The GBJ30M is a single-phase glass-passivated silicon bridge rectifier from the GBJ series, manufactured by GeneSiC Semiconductor. It features a maximum average forward rectified current of 30 A at a case temperature of 98 °C and a repetitive peak reverse voltage of 1000 V. The device operates within a junction temperature range of -50 °C to +150 °C. Key electrical parameters include a maximum forward voltage of 1.05 V at 15 A and a maximum reverse leakage current of 5 μA at 25 °C. It supports a maximum forward surge current of 420 A under specified pulse conditions.

Feature Summary

• Single in-line DIP package design for compact mounting
• Glass passivation provides protection against mechanical stress
• Epoxy resin material meets UL 94V-0 flammability standards

Applications

• AC-to-DC conversion circuits
• Power supply units requiring high surge capability
• General purpose rectification in industrial equipment

Procurement Notes

Verify component authenticity through official manufacturer channels or authorized distributors. Confirm RoHS compliance status and specific datasheet revisions prior to procurement. Ensure storage conditions maintain integrity of the glass-passivated silicon structure. Validate terminal configuration matches circuit board layout requirements before finalizing orders.

Selection Notes

Select this component when a 1000 V blocking voltage is required alongside 30 A continuous current capacity. Consider thermal resistance values based on heatsink availability; use recommended 15.2x15.2x12.8 cm heatsinks for optimal performance. Derate current by 20% if applied to capacitive loads. Ensure PCB mounting torque adheres to the 0.8 Nm recommendation for reliable connection.

Part Context

The GBJ30M belongs to the GBJ30J through GBJ30M family of single-phase bridge rectifiers. This series offers varying voltage ratings from 600 V to 1000 V while maintaining consistent current handling capabilities. The GBJ package format provides a standardized footprint for through-hole mounting, facilitating integration into various power electronics designs requiring robust rectification.

Replacement Considerations

Direct substitutes within the same voltage and current class include other GBJ30M equivalents from different manufacturers. Verify pinout compatibility and thermal characteristics when cross-referencing with alternative brands. Ensure replacement parts meet the same 1000 V VRRM and 30 A IO specifications.
