GBJ15B

Bridge Rectifier Overview

The GBJ15B is a single-phase glass-passivated silicon bridge rectifier manufactured by GeneSiC Semiconductor. It features a compact GBJ package designed for high heat-conducting performance and thermal welding capability at 260°C for 10 seconds. The device supports a repetitive peak reverse voltage of 100 V and delivers a maximum average forward rectified current of 15 A under resistive load conditions at 25°C ambient temperature. Electrical characteristics include a maximum forward voltage of 1.05 V at 7.5 A and a maximum reverse leakage current of 5 µA at 25°C. The component operates within a junction temperature range of -50°C to +150°C and withstands a maximum forward surge current of 250 A.

Bridge Rectifier Feature Summary

• Single in-line DIP package with small size and high heat-conducting performance
• Epoxy resin material compliant with UL 94V-0 flammability standards
• High surge current capability with robust thermal welding performance

Bridge Rectifier Applications

• General-purpose AC to DC power supply circuits
• Half-wave or full-wave rectification in low-voltage applications
• Power adapters and chargers requiring compact form factors

Bridge Rectifier Procurement Notes

Verify the specific manufacturer designation, as the provided documentation originates from diodemodule.com rather than GeneSiC Semiconductor directly. Confirm that the component meets RoHS provisions and UL 94V-0 flammability requirements before integration. Ensure the procurement source provides official datasheets matching the GBJ15B electrical parameters to avoid counterfeit components.

Bridge Rectifier Selection Notes

Select this component for applications requiring a 100 V reverse voltage rating and 15 A continuous current capacity. Consider the GBJ package dimensions and mounting torque specifications (0.8 Nm recommended) during PCB layout. Derate the forward current by 20% if the application involves capacitive loads to ensure reliable operation within the specified thermal limits.

Bridge Rectifier Part Context

The GBJ15B belongs to the GBJ series of single-phase bridge rectifiers, which includes variants with different voltage ratings such as GBJ15D, GBJ15G, and others up to 400 V. This series utilizes a standardized GBJ package footprint, allowing for design flexibility across different voltage requirements while maintaining consistent mechanical and thermal interface characteristics for manufacturing scalability.

Bridge Rectifier Replacement Considerations

Compatible replacements within the same series include GBJ15D (200 V), GBJ15F (300 V), and GBJ15G (400 V), provided the system voltage does not exceed their respective ratings. Other manufacturers offering equivalent GBJ-form-factor bridge rectifiers with matching 15 A current and 100 V voltage ratings may also serve as functional substitutes.
