Overview
The GBU1508-G is a single-phase bridge rectifier manufactured by Comchip Technology, designed for through-hole mounting in the GBU-4 package. It utilizes silicon technology to provide an average forward current (If) of 15 A and a peak repetitive reverse voltage (Vrrm) of 800 V. The device exhibits a maximum forward voltage drop (Vf) of 1 V at 7.5 A and a maximum non-repetitive surge current of 240 A. Operating within a temperature range of -55°C to +150°C junction temperature, it features a low reverse leakage current of 10 µA at 800 V.
Feature Summary
- Single-phase bridge configuration for AC-to-DC conversion
- Through-hole solder pin termination for PCB integration
- High thermal stability with extended operating temperature range
Applications
- General-purpose power supply circuits
- AC-DC rectification in industrial equipment
- Battery charging systems
Procurement Notes
Verify component authenticity by cross-referencing the manufacturer part number GBU1508-G with official Comchip Technology documentation. Confirm RoHS compliance status via the specific datasheet provided by the supplier. Ensure the ordering suffix matches the required packaging format, as variations may exist between tube and bulk configurations depending on the distributor source.
Selection Notes
Select this component when a 15 A continuous current rating and 800 V blocking voltage are required for high-power applications. The GBU-4 package offers robust mechanical stability for through-hole assembly. Verify that the 1 V forward voltage drop aligns with system efficiency targets and that the 240 A surge capability meets the inrush current requirements of the specific load.
Part Context
This component belongs to the GBU1508 series of bridge rectifiers from Comchip Technology. The series typically includes variants with different voltage ratings while maintaining the same 15 A current capacity and GBU-4 package footprint. This standardization allows for design flexibility across different voltage requirements within the same physical form factor.
Replacement Considerations
Compatible substitutes include other 15 A, 800 V single-phase bridge rectifiers in the GBU-4 package. Examples include parts from manufacturers such as Vishay or Diodes Inc., provided they match the pinout, thermal characteristics, and electrical specifications of the original component.
