GBJ3508

Overview

The GBJ3508 is a single-phase standard bridge rectifier manufactured by SMC Diode Solutions. It features an average rectified current (Io) of 35 A and a maximum repetitive peak reverse voltage (Vrrm) of 800 V. The forward voltage drop (Vf) is specified as 1.1 V at the rated current, with a reverse leakage current of 5 µA at 800 V. Designed for surface-mount or through-hole applications using the GBJ package (4-ESIP), it operates within a junction temperature range of -55°C to 150°C. The component complies with RoHS3 standards and has a moisture sensitivity level of 1.

Feature Summary

• High current capacity suitable for power supply circuits
• Wide operating temperature range for industrial environments
• Standard recovery characteristics for general-purpose rectification

Applications

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

Procurement Notes

Verify the specific package variant and marking code against the manufacturer's latest datasheet before ordering. Confirm compliance requirements such as RoHS3 and REACH status with the supplier. Ensure the procurement channel provides authentic components from SMC Diode Solutions to avoid counterfeits. Check for any recent product change notices that may affect pinout or material composition.

Selection Notes

Select this component when a 35 A current rating and 800 V blocking voltage are required in a compact GBJ footprint. Compare forward voltage drop and thermal resistance against alternatives if efficiency is critical. Ensure the PCB layout supports the 4-ESIP package dimensions and adequate copper area for heat dissipation at full load conditions.

Part Context

The GBJ3508 belongs to the GBJ series of single-phase bridge rectifiers from SMC Diode Solutions. This series offers various current ratings and voltage options within the same mechanical footprint, facilitating design flexibility. The GBJ package allows for robust soldering connections suitable for high-current applications.

Replacement Considerations

Direct replacements must match the 35 A current rating, 800 V voltage rating, and 4-ESIP package type. Verify that alternative bridge rectifiers have comparable forward voltage and reverse leakage specifications to ensure circuit performance parity.
