GBJ25K

Overview

The GBJ25K is a single-phase bridge rectifier manufactured by Good-Ark Semiconductor, designed for general-purpose power conversion applications. This component utilizes glass passivated rectifier chips to ensure high reliability and low reverse leakage current. It features a molded plastic case with UL recognition and a flammability classification of 94V-0. The device supports a maximum repetitive peak reverse voltage ranging from 50 V to 1000 V, depending on the specific voltage code variant. It provides an average forward rectified current of 25.0 A and offers high surge current capability suitable for demanding environments. The unit is housed in a through-hole GBJ package with plated leads that are solderable per MIL-STD-750 Method 2026.

Feature Summary

• Internal construction incorporates glass passivated rectifier chips (GPRC) for enhanced stability.
• High case dielectric strength rated at 1500 VRMS for improved isolation safety.
• Molded polarity indicators on the body facilitate correct circuit orientation during assembly.

Applications

• Printed Circuit Board (PCB) mounting for AC-to-DC power supplies
• General purpose rectification in industrial equipment
• Power adapters requiring high surge current handling

Procurement Notes

Verify the specific voltage suffix corresponding to the required Reverse Voltage rating, as the GBJ25K series spans multiple voltage codes from 50 V to 1000 V. Confirm compliance with RoHS directives and check for specific automotive or industrial qualification requirements if applicable to the end-use environment. Ensure the ordering part number matches the exact current and voltage specifications needed for the design.

Selection Notes

Select this component when a 25 A single-phase bridge rectifier with through-hole mounting is required. The GBJ package allows for secure mechanical attachment using #6 screws with a maximum torque of 5.0 in-lbs. Consider the thermal management capabilities of the GBJ molded plastic case and verify that the operating temperature range meets the system's environmental constraints.

Part Context

The GBJ25K belongs to the Glass Passivated Single-Phase Bridge Rectifier family produced by Good-Ark Semiconductor. This series is characterized by its robust construction and suitability for high-current applications. The GBJ form factor is widely recognized in the industry for providing a compact yet durable solution for PCB-based power supply designs.

Replacement Considerations

Cross-reference with other manufacturers offering GBJ25K equivalents, such as Won-Top Electronics, SeCoS Halbleiter, or SEMTECH Electronics. Verify that substitute parts maintain identical pinout configurations, current ratings, and voltage codes to ensure direct compatibility without redesigning the footprint or circuit layout.
