GBU1008

Overview

The MDD GBU1008 is a through-hole glass passivated single-phase bridge rectifier belonging to the GBU series. It features a molded plastic body with UL flammability classification 94V-0 and is designed for printed circuit board mounting. The device supports a maximum repetitive peak reverse voltage of 800 V and an average forward rectified current of 10 A at a case temperature of 100°C. It withstands a peak forward surge current of 220 A under JEDEC testing conditions. The component operates within a junction temperature range of -55°C to +150°C and exhibits a typical forward voltage of 1.0 V at 5.0 A DC.

Procurement Notes

Verify the original manufacturer designation as MDD against the specific part code GBU100800L1080 provided in the specification sheet. Confirm that the package configuration matches the bulk box requirement of 500 pieces per box. Ensure the reverse voltage rating of 800 V aligns with the target circuit design requirements before finalizing procurement orders.

Selection Notes

Select this component when a 10 A continuous current rating and 800 V blocking voltage are required for through-hole applications. Consider the thermal resistance of 2.2 °C/W and the operating temperature range up to 150°C for high-temperature environments. Verify compatibility with PCB mounting styles and ensure adequate heatsinking if operating near the maximum current limit at elevated ambient temperatures.

Part Context

This component belongs to the GBU series of through-hole bridge rectifiers, which offers various voltage ratings from 50 V to 1000 V while maintaining a consistent 10 A current capacity. The GBU1008 specifically addresses applications requiring higher reverse voltage endurance compared to lower-rated variants like the GBU1005 or GBU1006 within the same physical footprint and mechanical design family.

Replacement Considerations

Cross-reference part numbers such as GBU100800L1080 may serve as equivalents. Verify mechanical dimensions and pinout configurations match the existing PCB layout. Ensure electrical parameters including reverse voltage and forward current ratings meet or exceed the original design specifications.
