GBJ30J

Overview

The GBJ30J is a single-phase glass-passivated silicon bridge rectifier manufactured by GeneSiC Semiconductor. It features a maximum average forward rectified current of 30 A and a repetitive peak reverse voltage of 600 V. The device utilizes a compact GBJ DIP package with epoxy resin compliant with UL 94V-0 flammability standards. Electrical characteristics include a maximum forward voltage of 1.05 V at 15 A and a maximum reverse leakage current of 5 μA at rated DC blocking voltage. It supports an operating junction temperature range from -50 °C to +150 °C and offers high surge current capability.

Feature Summary

• Single-phase glass-passivated silicon construction for reliable rectification
• Compact GBJ in-line DIP package design
• High thermal conductivity with low forward voltage drop
• Epoxy resin material meets UL 94V-0 flammability standards

Applications

• AC to DC power supply circuits
• Battery charging systems
• General-purpose rectification in industrial equipment

Procurement Notes

Verify the specific datasheet version and manufacturer details, as some distributor listings may reference alternative brands or discontinued status. Confirm RoHS compliance and packaging type (bulk) directly with the supplier before ordering. Ensure the 600 V rating aligns with the circuit requirements, noting that higher voltage variants exist within the same product family.

Selection Notes

Select the GBJ30J when a 600 V reverse voltage rating and 30 A continuous current are required. Consider the GBJ30K or GBJ30M if the application demands higher voltage ratings of 800 V or 1000 V respectively. Evaluate the thermal resistance values based on whether a heatsink is used, as the maximum current rating decreases significantly without one. Ensure the PCB layout accommodates the specified mounting torque and terminal spacing.

Part Context

The GBJ30J belongs to the GBJ series of single-phase bridge rectifiers, which also includes variants like the GBJ30K and GBJ30M offering different voltage ratings. This series is characterized by its robust glass passivation and compact DIP packaging, suitable for space-constrained applications requiring high current handling. The component is part of GeneSiC Semiconductor's broader portfolio of diode modules and discrete rectifiers.

Replacement Considerations

Direct replacements within the same voltage and current class include the GBJ30K (800 V) and GBJ30M (1000 V), provided the voltage headroom is sufficient. Other generic GBJ30 packages from different manufacturers may serve as substitutes if pinout and thermal specifications match.
