GBJ35K

Overview

The GBJ35K is a single-phase silicon bridge rectifier from the GBJ35 series, manufactured by GeneSiC Semiconductor. It features a glass-passivated junction and operates within a repetitive peak reverse voltage range of 600 V to 1000 V. The device supports a maximum average forward rectified current of 35 A at a case temperature of 98 °C. Electrical characteristics include a maximum forward voltage of 1.05 V at 17.5 A and a maximum reverse leakage current of 5 µA at 25 °C. The component utilizes a compact DIP package with dimensions of 30 mm x 4.6 mm x 20 mm, designed for through-hole mounting.

Feature Summary

• Glass-passivated junction construction ensures high reliability and stable electrical performance under varying thermal conditions.
• Compact single in-line DIP package design facilitates efficient PCB layout while maintaining high heat-conducting capabilities.
• High surge current capability allows the device to withstand transient overloads during standard half-sine wave pulses.

Applications

• AC-to-DC conversion circuits requiring robust rectification at elevated voltages
• Power supply units operating within the 600 V to 1000 V reverse voltage specifications
• Industrial equipment utilizing through-hole mounted bridge rectifiers

Procurement Notes

Verify the specific reverse voltage rating required for the application, as the GBJ35K belongs to a series covering 600 V to 1000 V. Confirm that the manufacturer designation aligns with GeneSiC Semiconductor specifications. Ensure compliance with RoHS provisions and UL 94V-0 flammability standards if mandated by the end-use environment. Cross-reference datasheet parameters against actual circuit requirements before finalizing procurement.

Selection Notes

Select the GBJ35K when applications demand a 35 A continuous current rating combined with high reverse voltage blocking capabilities up to 1000 V. Consider the thermal resistance values provided for both heatsinked and non-heatsinked configurations to ensure proper junction temperature management. Evaluate the physical footprint constraints of the GBJ package against available PCB real estate. Derate current by 20% if the load is capacitive to maintain operational safety margins.

Part Context

The GBJ35K is part of the GBJ35J through GBJ35M family of single-phase bridge rectifiers. This series shares identical physical dimensions and general electrical characteristics, differing primarily in their maximum repetitive peak reverse voltage ratings. The GBJ package is standardized across these variants, allowing for consistent mechanical integration in designs requiring various voltage levels within the same current capacity class.

Replacement Considerations

Direct substitutes within the same series include GBJ35J (600 V), GBJ35L (800 V), and GBJ35M (1000 V). Selection depends on matching the specific reverse voltage requirement of the target circuit. Other manufacturers offering equivalent GBJ-style 35 A bridge rectifiers may be considered if pin compatibility and thermal characteristics are verified.
