GBU810

Overview

The MDD GBU810 is a single-phase bridge rectifier utilizing glass-passivated silicon junctions within a molded plastic GBU package. It provides a maximum repetitive peak reverse voltage of 1000V and an average forward rectified current of 8.0A at a case temperature of 100°C. The device supports a peak forward surge current of 200A for an 8.3ms half-sine wave. Electrical characteristics include a maximum forward voltage of 1.0V at 5.0A DC and a reverse leakage current of 10µA at 25°C, rising to 0.5mA at 125°C. The component operates across a junction temperature range from -55°C to +150°C with a thermal resistance of 2.2°C/W.

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm packaging details. The provided specification sheet indicates bulk packaging containing 500 pieces per box. Confirm that the requested part matches the exact electrical ratings and mechanical dimensions required for your design implementation before finalizing orders.

Selection Notes

Select this component when a 1000V blocking capability and 8A continuous current are required in a through-hole configuration. Ensure adequate heatsinking or airflow is available if operating near the maximum thermal limits. Verify that the PCB layout accommodates the specific lead spacing and physical footprint defined in the mechanical data section of the datasheet.

Part Context

This component belongs to the GBU series of bridge rectifiers manufactured by MDD. The series offers various voltage and current combinations within the same standardized GBU package form factor. This specific model represents the 1000V/8A variant within the lineup, designed for general rectification tasks where robustness and standard mounting are prioritized.

Replacement Considerations

Cross-reference with other manufacturers offering identical GBU-4 packages rated for 1000V and 8A. Ensure equivalent surge current ratings and thermal resistance values are met. Verify pinout compatibility and physical dimensions to guarantee direct replacement without PCB modifications.
