Overview
The MDD GBU808 is a through-hole glass-passivated bridge rectifier from the GBU series. It features a molded plastic body with UL flammability classification 94V-0 and solder-plated terminals. The device supports a maximum repetitive peak reverse voltage of 800 V and an average forward rectified current of 8.0 A at a case temperature of 100°C. It withstands a peak forward surge current of 200 A for an 8.3 ms half-sine wave. The component operates within a junction temperature range of -55°C to +150°C and exhibits a typical thermal resistance of 2.2 °C/W.
Feature Summary
- Glass passivation provides reliable protection against environmental stressors.
- Molded plastic construction ensures low-cost assembly and mechanical durability.
- High surge overload rating accommodates transient current spikes during operation.
Applications
- Printed circuit board power supply circuits
- General-purpose AC to DC rectification
- Industrial equipment power modules
Procurement Notes
Verify that the specific order matches the original part number MDD GBU808. Confirm the package quantity corresponds to bulk boxes containing 500 pieces per box as specified in the documentation. Ensure compliance with RoHS and RoHS III standards if required by the end application. Cross-reference the internal part code GBU0808000L880 to confirm exact specifications before finalizing procurement.
Selection Notes
Select this component when an 800 V reverse voltage rating and 8 A continuous current capacity are required for through-hole mounting. The GBU808 is suitable for applications needing high surge tolerance up to 200 A. Consider the 2.2 °C/W thermal resistance for heatsinking requirements. Verify that the operating environment stays within the -55°C to +150°C junction temperature limits.
Part Context
The GBU808 belongs to the GBU series of through-hole bridge rectifiers manufactured by MDD. This series utilizes a glass-passivated junction and a molded plastic case designed for PCB mounting. The product line includes various voltage and current ratings, with the GBU808 specifically designated for 800 V and 8 A applications.
Replacement Considerations
Cross-reference part numbers such as GBU0808000L880 may be used for identification. Verify electrical parameters including 800 V reverse voltage and 8 A forward current match exactly before substitution.
