GBJ8M

Overview

The GBJ8M is a silicon bridge rectifier diode manufactured by Surge Components. It features a single-phase configuration with four internal elements housed in a plastic/epoxy flange mount package. The device supports a maximum output current of 8 A and offers a maximum repetitive peak reverse voltage ranging from 50 V to 1000 V, with the 'M' suffix typically denoting an 800 V rating. It has a maximum non-repetitive peak forward surge current of 200 A. The component utilizes wire terminals positioned on the upper side for through-hole mounting.

Feature Summary

• High forward surge current capability for transient protection
• Plastic package rated for high-temperature soldering up to 260°C
• Underwriters Laboratory flammability classification 94V-0

Applications

• Printed circuit board power supply circuits
• General purpose AC to DC conversion
• Bridge rectifier applications requiring 8A continuous current

Procurement Notes

Verify the specific voltage code suffix (e.g., M for 800V) against the required circuit breakdown voltage. Confirm the manufacturer is Surge Components or authorized equivalent. Ensure the flange mount package dimensions match the PCB footprint. Check for RoHS compliance if environmental standards are mandatory for the assembly.

Selection Notes

Select based on the required RMS output current of 8 A and the peak inverse voltage needed for the AC input line. The GBJ series is suitable for general-purpose applications where low reverse leakage and high temperature stability are required. Ensure the thermal management strategy accounts for the flange mount design to dissipate heat effectively during operation.

Part Context

The GBJ8M belongs to the KBU/GJ series of silicon bridge rectifiers produced by Surge Components. This series is characterized by its robust plastic encapsulation and high surge current handling capabilities. It serves as a standard solution for converting AC voltage to DC in various electronic equipment, offering reliability under high-temperature conditions.

Replacement Considerations

Equivalent parts include the GBPC808 or similar 8A, 800V bridge rectifiers from other manufacturers. Verify pinout compatibility and physical dimensions before substitution. Ensure the replacement part meets the same thermal and electrical ratings for safe integration.
