GBJ25B

Bridge Rectifier Overview

The GBJ25B is a single-phase glass-passivated silicon bridge rectifier manufactured by GeneSiC Semiconductor. It features a maximum average forward rectified current of 25 A and a repetitive peak reverse voltage of 100 V. The device exhibits a maximum forward voltage of 1.05 V at 12.5 A and a maximum reverse leakage current of 5 µA at 25 °C. It supports a maximum forward surge current of 500 A under specified conditions. The component operates within an ambient temperature range of -50 °C to 150 °C and utilizes a compact Single in-line DIP package compliant with UL 94V-0 flammability standards.

Bridge Rectifier Feature Summary

• Single in-line DIP package design for compact size and high heat-conducting performance
• Glass passivated junction construction ensuring low forward voltage and high forward current capability
• Epoxy resin material meeting UL 94V-0 flammability provisions

Bridge Rectifier Applications

• AC to DC conversion in resistive loads
• Half-wave rectification circuits operating at 60 Hz
• Power supply stages requiring high surge current capability

Bridge Rectifier Procurement Notes

Verify the specific manufacturer source, as datasheet URLs may indicate third-party distributors rather than direct GeneSiC Semiconductor production. Confirm RoHS compliance status and exact thermal resistance values based on the intended PCB mounting configuration and heatsink usage. Ensure the 100 V rating aligns with circuit requirements before procurement.

Bridge Rectifier Selection Notes

Select this component when a 25 A continuous current rating and 100 V reverse voltage are required in a compact DIP form factor. Consider the thermal resistance characteristics; performance varies significantly between installation with and without a heatsink. Derate current by 20% if used with capacitive loads to ensure reliable operation within the specified temperature limits.

Bridge Rectifier Part Context

The GBJ25B belongs to the GBJ series of single-phase glass-passivated silicon bridge rectifiers from GeneSiC Semiconductor. This series includes variants ranging from 100 V to 400 V reverse voltage while maintaining a consistent 25 A forward current capacity. The GBJ package is characterized by its small footprint and efficient thermal management capabilities suitable for various power electronics applications.

Bridge Rectifier Replacement Considerations

Compatible substitutes include other GBJ25xx series parts such as GBJ25D (200 V) or GBJ25G (400 V), provided the voltage rating exceeds the circuit's peak inverse voltage. Generic equivalents must match the 25 A current rating, 1.05 V forward voltage, and DO-201AB physical dimensions.
