Overview
The GBU2508-HF is a single-phase bridge rectifier manufactured by Comchip Technology. It features a peak repetitive reverse voltage of 800 V and an average forward rectified current of 25 A. The device exhibits a maximum forward voltage drop of 1 V at 12.5 A and a maximum non-repetitive surge current of 350 A. Operating within a temperature range of -55°C to +150°C junction temperature, it utilizes a GBU-4 through-hole package with solder pin termination.
Feature Summary
- High thermal stability for demanding environments
- Robust surge current handling capability
- Standard silicon rectification technology
Applications
- General purpose power supply circuits
- Battery charging systems
- DC-to-DC conversion modules
Procurement Notes
Verify the manufacturer part number against official Comchip Technology documentation to ensure authenticity. Confirm RoHS compliance status directly from the datasheet. Check for any specific ordering suffixes that may indicate packaging variations. Ensure the component matches the required electrical specifications for the target design before procurement.
Selection Notes
Select this component when an 800 V blocking voltage and 25 A continuous current rating are required in a GBU package. Consider the 1 V forward voltage drop for thermal management calculations. Verify that the through-hole mounting style fits the PCB layout constraints. Compare leakage current specifications if low standby power is critical.
Part Context
This component belongs to the GBU series of bridge rectifiers from Comchip Technology. The series offers various voltage ratings while maintaining consistent current handling and package dimensions. The GBU2508-HF specifically targets applications requiring high voltage isolation with moderate to high current capacity in a standard through-hole form factor.
Replacement Considerations
Direct substitutes must match the 25 A current, 800 V voltage, and GBU package. Verify equivalent forward voltage and leakage characteristics. Cross-reference with other manufacturers offering GBU-style bridge rectifiers with identical electrical ratings.
