GBU1010

Overview

The MDD GBU1010 is a glass passivated single-phase bridge rectifier in the GBU series, designed for through-hole mounting. It features a molded plastic body with UL flammability classification 94V-0 and solder-plated terminals. The device supports a repetitive peak reverse voltage of 1000V and an average forward rectified current of 10A at Tc=100°C. Key electrical parameters include a peak forward surge current of 220A, a maximum forward voltage of 1.0V at 5.0A DC, and a thermal resistance (RθJA) of 2.2°C/W. Operating junction temperature ranges from -55°C to +150°C.

Feature Summary

• Glass passivated chip junctions provide reliable low-cost construction utilizing molded plastic techniques.
• Suitable for printed circuit board applications with any mounting position.
• Plastic material meets Underwriters Laboratory flammability classification 94V-0.

Applications

• General purpose power supply circuits
• Industrial electronic equipment
• Consumer electronics AC-to-DC conversion

Procurement Notes

Verify that the component matches the original MDD specification sheet N0310-GBU1010000L10A. Confirm the package type is bulk with 500 pieces per box as indicated by the 'L' code. Ensure the marking on the body reads GBU1010 and check for RoHS/RoHS III compliance documentation before finalizing procurement orders.

Selection Notes

Select this component when a 1000V rating and 10A continuous current are required for single-phase rectification. Consider the 220A surge capability for inrush protection. Verify thermal management requirements against the 2.2°C/W thermal resistance value if operating near the maximum junction temperature limit.

Part Context

The GBU1010 belongs to the GBU series of glass passivated bridge rectifiers manufactured by MDD. This series covers various voltage and current ratings, ranging from lower amperage models like GBU0406 to higher capacity units like GBU2510. The GBU1010 specifically targets high-voltage, medium-current applications within this standardized through-hole family.

Replacement Considerations

Cross-reference part numbers such as DiodesZetex GBU1010 or HY Electronic GBU1010 for potential substitutes. Verify that alternative manufacturers meet the same 1000V VRRM, 10A IAV, and GBU package dimensions to ensure mechanical and electrical compatibility.

FAQ

What is the maximum forward surge current rating?

The peak forward surge current (IFSM) is rated at 220A for an 8.3ms single half sine-wave superimposed on rated load.

How does capacitive loading affect the current rating?

For capacitive loads, the average forward rectified current must be derated by 20% compared to resistive or inductive loads.

What is the typical junction capacitance?

The junction capacitance (CJ) is typically 70 pF, measured at 1MHz with an applied reverse voltage of 4.0V DC.
