GBJ35J

Overview

The GBJ35J is a single-phase glass-passivated silicon bridge rectifier manufactured by GeneSiC Semiconductor. It features a GBJ package with a maximum average forward rectified current (IO) of 35 A at a case temperature of 98 °C and a peak repetitive reverse voltage (VRRM) of 600 V. The device exhibits a maximum forward voltage (VF) of 1.05 V at an average forward current of 17.5 A and a maximum non-repetitive surge current (IFSM) of 500 A for an 8.3 ms pulse. Operating temperatures range from -50 °C to +150 °C, with a thermal resistance (RΘJA) of 28 °C/W without a heatsink.

Feature Summary

• Single in-line DIP package design providing compact size and high heat-conducting performance.
• Glass passivation ensures stable electrical characteristics and compliance with UL 94V-0 flammability standards.
• High surge current capability supports robust operation under transient load conditions.

Applications

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

Procurement Notes

Verify the specific voltage rating required for the application, as the GBJ35J is rated for 600 V. Confirm that the manufacturer documentation aligns with the intended operational parameters. Ensure proper mounting torque and thermal interface materials are used to maintain specified thermal resistance values during installation.

Selection Notes

Select this component when a 600 V blocking voltage and 35 A continuous current capacity are required in a through-hole DIP format. Consider the thermal management requirements, as the device relies on external heatsinking or PCB copper area to dissipate heat effectively within the specified operating temperature range.

Part Context

The GBJ35J belongs to the GBJ series of single-phase bridge rectifiers, which includes variants with different voltage ratings such as GBJ35K, GBJ35M, and others. This series shares common physical dimensions and packaging characteristics while varying in peak reverse voltage specifications to suit diverse circuit requirements.

Replacement Considerations

Cross-reference with other GBJ35xx series components like GBJ35K or GBJ35M if higher voltage ratings are needed. Verify pinout compatibility and thermal characteristics before substituting with equivalent parts from other manufacturers.

FAQ

What is the maximum forward surge current for the GBJ35J?

The maximum non-repetitive forward surge current (IFSM) is 500 A for an 8.3 ms pulse width at a rated load with an initial junction temperature of 25 °C.

How does the GBJ35J handle capacitive loads?

For capacitive loads, the forward current should be derated by 20% to ensure reliable operation and prevent excessive stress on the rectifier.

What is the insulation strength of the GBJ35J?

The insulation strength between the lead wire and the case is rated at 2.5 kV AC for one minute with a leakage current less than 1 mA.
