GBU8M

Overview

The onsemi GBU8M is a single-phase bridge rectifier from the GBU8 series, designed for general-purpose rectification in power supply applications. It features an average forward current of 8A and a maximum repetitive peak reverse voltage of 1000V. The device utilizes silicon junction technology with glass passivation for isolation between elements and terminals. Key electrical parameters include a peak non-repetitive forward surge current (Ifsm) of 200A at 60Hz sine wave, a maximum DC blocking current of 5µA at rated voltage, and a peak forward voltage of 1V at 8A. It operates within a temperature range of -55°C to +150°C junction temperature.

Feature Summary

Glass passivated junctions provide high reliability and isolation between elements and terminals.
High surge current capability supports robust performance during transient load conditions.
Designed for printed circuit board mounting using wire lead structures.

Applications

General purpose rectification in AC-DC power supplies.
Battery chargers requiring high voltage blocking capabilities.
Industrial power conversion equipment.

Procurement Notes

Verify the specific suffix against official datasheets to confirm voltage ratings, as variations exist within the GBU8 family. Confirm RoHS compliance status through manufacturer declarations or material data sheets prior to integration. Ensure thermal management strategies align with the specified junction temperature limits during operation.

Selection Notes

Select this component when a 1000V rating is required for single-phase rectification with 8A continuous current. Compare against lower voltage variants like GBU8G (400V) or GBU8K (800V) based on circuit requirements. Verify package dimensions match PCB footprint constraints, specifically the GBU 4-SIP form factor.

Part Context

The GBU8M belongs to the GBU8 series of single-phase bridge rectifiers manufactured by onsemi. This series shares common packaging and basic structural characteristics but varies primarily in peak reverse voltage ratings. The M suffix typically denotes the 1000V variant within this product line.
