GBU808-01-LS

Overview

The GBU808-01-LS is a single-phase silicon bridge rectifier manufactured by Diodes Incorporated under the GBU8005 series. It features an 800V repetitive peak reverse voltage (Vrrm) and an average forward rectified current (If) of 8A at 45°C ambient temperature. The device supports a peak non-repetitive forward surge current (Ifsm) of 200A for half-sine waves at 60Hz. Electrical characteristics include a maximum DC blocking voltage of 560V, a maximum RMS input voltage of 560V, and a peak forward voltage drop of 1.2V at 8A. Reverse leakage current is limited to 5μA at rated Vrrm. The component operates within a junction temperature range of -55°C to +150°C and is housed in a GBU plastic package with through-hole mounting.

Feature Summary

• High thermal stability enabling operation up to 150°C junction temperature
• Robust surge overload capability rated at 200A peak forward current
• Low leakage current ensuring efficient performance under high reverse bias conditions

Applications

• General-purpose AC-to-DC power supply rectification
• Industrial equipment power conversion circuits
• Consumer electronics adapter applications

Procurement Notes

Verify the manufacturer part number GBU808-01-LS against official Diodes Incorporated documentation to confirm specifications. Ensure compliance with RoHS directives and automotive qualification standards AEC-Q101, AEC-Q200, and AEC-Q100 as specified in the datasheet. Confirm package type and pin configuration match system requirements before procurement.

Selection Notes

Select this component for applications requiring 8A continuous current handling and 800V reverse voltage blocking. Consider the GBU package dimensions for PCB layout constraints. Evaluate thermal management needs given the 150°C maximum operating temperature. Verify that the 1.2V forward voltage drop aligns with efficiency targets for the specific circuit design.

Part Context

This rectifier belongs to the GBU8005 series from Diodes Incorporated, designed for general-purpose rectification tasks. The GBU package provides reliable low-cost construction suitable for printed circuit board mounting. The component utilizes glass-passivated junction technology for improved reliability compared to unpassivated alternatives.

Replacement Considerations

Direct substitutes must match the 8A current rating, 800V reverse voltage, and GBU package footprint. Verify equivalent electrical parameters such as forward voltage drop and reverse leakage current. Ensure replacement components meet the same thermal and mechanical specifications for seamless integration.
