GBJ35B

Overview

The GBJ35B is a single-phase glass-passivated silicon bridge rectifier manufactured by GeneSiC Semiconductor. It features a repetitive peak reverse voltage of 100 V and a maximum average forward rectified current of 35 A at an ambient temperature of 25 °C. The device exhibits a maximum forward voltage of 1.05 V at 17.5 A and supports a maximum forward surge current of 500 A under specified pulse conditions. Operating within a junction temperature range of -50 °C to +150 °C, the component utilizes a GBJ through-hole package with solder pin termination.

Feature Summary

• Single in-line DIP package design providing compact size and high heat-conducting performance
• Epoxy resin material compliant with UL 94V-0 flammability standards
• High surge current capability with low forward voltage characteristics
• Compliant with RoHS provisions for environmental safety

Applications

• General purpose AC to DC conversion circuits
• Power supply units requiring robust thermal management
• Industrial control systems utilizing single-phase bridge rectification

Procurement Notes

Verify the specific manufacturer designation on the datasheet, as distributor listings may reference Navitas Semiconductor or GeneSiC Semiconductor interchangeably due to corporate acquisitions. Confirm that the procurement matches the exact GBJ35B part number to ensure the correct 100 V rating, as other variants in the series possess different voltage specifications. Check for discontinuation status before finalizing orders.

Selection Notes

Select this component when a 100 V blocking voltage is required alongside a 35 A continuous current capacity. Ensure the application allows for adequate heatsinking, as the rated current depends on mounting to a specified heatsink size; operation without a heatsink significantly reduces the allowable current. Verify that the operating environment stays within the -50 °C to +150 °C junction temperature limits.

Part Context

The GBJ35B belongs to the GBJ series of single-phase bridge rectifiers, which are available in various voltage ratings ranging from 100 V to 400 V. This series shares a common physical footprint and terminal configuration, allowing for potential mechanical compatibility with other members of the family, such as the GBJ35D or GBJ35G, provided their electrical ratings suit the circuit requirements.

Replacement Considerations

Direct substitutes include other GBJ35x series components like the GBJ35D or GBJ35G if higher voltage ratings are acceptable. Generic replacements must match the 35 A current, 100 V minimum reverse voltage, and GBJ package dimensions. Verify that any alternative maintains similar thermal resistance and forward voltage characteristics.
