GBU2010S-BP

Overview

The GBU2010S-BP is a single-phase glass-passivated bridge rectifier manufactured by Micro Commercial Components (MCC). It features a maximum average forward current of 3.5A and a peak repetitive reverse voltage of 1000V. The device operates within a junction temperature range of -55°C to +150°C and provides a high surge overload rating of 250A for an 8.3ms half-sine wave. Electrical characteristics include a maximum forward voltage drop of 1.0V and a maximum DC reverse current of 5μA at rated blocking voltage. The component utilizes a GBU surface-mount package with lead-free finish and RoHS compliance.

Feature Summary

• Glass-passivated construction ensures long-term stability and reliability under various operating conditions.
• High surge overload capability supports handling transient current spikes during power-up or fault events.
• Halogen-free 'Green' device formulation meets environmental standards for restricted hazardous substances.

Applications

• AC-DC power supply circuits requiring high-voltage isolation.
• Bridge rectification in general-purpose electronic equipment.
• Adapters and chargers operating within specified thermal limits.

Procurement Notes

Verify authenticity through authorized MCC distributors to avoid counterfeit components. Confirm the specific ordering suffix matches required packaging quantities, such as bulk tubes or cartons. Ensure the procurement documentation includes traceability records and compliance certificates for RoHS and halogen-free status prior to final acquisition.

Selection Notes

Select this component when a 1000V reverse voltage rating is necessary for single-phase bridge applications. The 3.5A average current limit dictates suitability for low-to-medium power loads. Evaluate thermal management requirements based on the 1.5°C/W junction-to-case resistance if heatsinking is employed in the design.

Part Context

This part belongs to the GBU series of surface-mount bridge rectifiers from Micro Commercial Components. The series offers various voltage and current combinations tailored for compact PCB layouts. The GBU2010S variant specifically addresses high-voltage requirements within the standard GBU footprint dimensions.

Replacement Considerations

Direct substitutes must match the 1000V reverse voltage, 3.5A average current, and GBU package outline. Verify that alternative components maintain equivalent thermal resistance and surge current ratings to ensure circuit compatibility without redesigning the thermal interface.

FAQ

What is the typical junction capacitance of the GBU2010S?

The typical junction capacitance is 80 pF, measured at 1.0MHz with a reverse voltage of 4.0V.

Does the GBU2010S require a heatsink for operation?

Operation without a heatsink is supported up to 20A case temperature at 90°C, but derating curves should be consulted for ambient temperature conditions to ensure safe junction temperatures.

What is the dielectric strength between terminals and case?

The dielectric strength is rated at 2.5KV for one minute between terminals and the case.
