GBU806

Overview

The MDD GBU806 is a single-phase bridge rectifier utilizing glass-passivated silicon die within a molded plastic GBU-4 package. It supports through-hole mounting with solder pin termination. Key electrical parameters include a maximum repetitive peak reverse voltage of 600V and an average forward rectified current of 8.0A at Tc=100°C. The device withstands a peak forward surge current of 200A (8.3ms). Forward voltage is typically 1.0V at 4.0A DC, while reverse current is 10µA at 25°C. Operating junction temperature ranges from -55°C to +150°C.

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm packaging quantity and terminal plating specifications. Ensure the component meets RoHS compliance requirements for the target assembly process. Cross-reference the original part number GBU806 with the provided specification sheet N0626 to validate technical alignment before procurement.

Selection Notes

Select this component when a 600V blocking voltage and 8A continuous current rating are required for through-hole PCB assembly. Consider the 200A surge capability for applications with high inrush currents. Verify thermal management needs based on the 2.2°C/W thermal resistance and derating curves for capacitive loads.

Part Context
