GBI25J-LX

Bridge Rectifier Overview

The GBI25J-LV and GBI25J-LX are low forward voltage single-phase diode bridge rectifiers manufactured by Diotec Semiconductor. These devices feature a maximum average forward current (IFAV) of 25 A and a peak repetitive reverse voltage (VRRM) of 600 V. The GBI25J-LV exhibits a typical forward voltage of 0.87 V at 12.5 A, while the GBI25J-LX shows a typical forward voltage of 0.90 V under identical conditions. Both variants support a peak forward surge current of up to 360 A at 60 Hz and operate within a junction temperature range of -50°C to +150°C.

Bridge Rectifier Feature Summary

• Low forward voltage drop design for enhanced power conversion efficiency
• High surge current capability with specific ratings for 50 Hz and 60 Hz half-sine waves
• Robust thermal performance with defined junction-to-case resistance values

Bridge Rectifier Applications

• Motor drives in consumer electronics
• General industrial power supplies
• AC to DC rectification circuits requiring high efficiency

Bridge Rectifier Procurement Notes

Verify the exact suffix required for your application, as the LV and LX variants possess distinct forward voltage specifications. Confirm that the 600 V reverse voltage rating aligns with your circuit's peak inverse voltage requirements. Ensure mounting torque adheres to the specified M3 limit of 0.8 Nm plus or minus 10 percent to prevent mechanical damage during installation.

Bridge Rectifier Selection Notes

Select the GBI25J-LV when minimizing conduction losses is critical, given its lower typical forward voltage compared to the LX variant. Consider the thermal resistance parameters if designing for freestanding operation versus heatsink mounting. Verify that the protective resistance and load capacitor values comply with the manufacturer's guidelines to prevent exceeding the peak surge current limits during startup.

Bridge Rectifier Part Context

This component belongs to the GBI series of single-phase bridge rectifiers from Diotec Semiconductor. It utilizes a standard through-hole package suitable for PCB mounting. The device is constructed using silicon technology and complies with RoHS directives, making it suitable for commercial and industrial electronic equipment where standard reliability levels are required.

Bridge Rectifier Replacement Considerations

Direct replacements must match the 25 A current rating and 600 V reverse voltage. Verify that substitute components offer comparable forward voltage characteristics to maintain circuit efficiency. Ensure the replacement package matches the physical footprint and pin configuration of the GBI-4 style housing used by this part number.

Bridge Rectifier FAQ

What is the difference between the GBI25J-LV and GBI25J-LX?

The primary difference lies in the forward voltage. The GBI25J-LV has a typical forward voltage of 0.87 V at 12.5 A, whereas the GBI25J-LX has a typical forward voltage of 0.90 V at the same current.

What is the maximum peak forward surge current?

The maximum peak forward surge current is 325 A for a 50 Hz half-sine wave (10 ms duration) and 360 A for a 60 Hz half-sine wave (8.3 ms duration).

How should the leads be positioned for thermal resistance measurements?

Thermal resistance values are valid only if the leads are kept at ambient temperature at a distance of 5 mm from the case.
