Overview
The GBU808-G is a single-phase bridge rectifier manufactured by Comchip Technology, designed for through-hole mounting in the GBU-4 package. It features a silicon construction with a maximum average forward rectified current of 8 A and a peak repetitive reverse voltage rating of 800 V. The device exhibits a maximum forward voltage drop of 1.3 V at rated current and supports a non-repetitive peak surge current of 200 A. Operating temperatures range from -55°C to +150°C junction temperature, with a maximum reverse leakage current of 5 µA.
Feature Summary
- Glass passivated chip junctions provide stable performance and protection against voltage transients.
- High surge current capability ensures reliability during power-up or fault conditions.
- Low forward voltage drop contributes to improved system efficiency and reduced thermal stress.
Applications
- AC-to-DC conversion circuits
- Power supply units
- Battery chargers
Procurement Notes
Verify the specific manufacturer part number against official Comchip Technology documentation to ensure authenticity. Confirm RoHS compliance status and packaging details directly with authorized distributors. Cross-reference datasheet revisions to confirm pinout and electrical characteristics match design requirements before procurement.
Selection Notes
Select this component when an 8 A current rating and 800 V blocking voltage are required in a standard GBU-4 through-hole package. Ensure the application operates within the specified -55°C to +150°C temperature range. Verify that the PCB layout accommodates the physical dimensions and lead spacing of the GBU-4 housing for proper mechanical stability.
Part Context
This component belongs to the GBU series of single-phase bridge rectifiers from Comchip Technology. The series offers various current ratings and voltage options within the same GBU-4 form factor, allowing designers to maintain consistent board layouts while adjusting electrical specifications for different power handling needs.
Replacement Considerations
Compatible replacements include other manufacturers' GBU-808 equivalents such as the MDD GBU808 or LGE GBU808, provided they meet the 8 A / 800 V / GBU-4 package specifications. Verify pin compatibility and thermal characteristics before substitution.
