GBU806-K

Overview

The GBU806-K is an 8 A, 800 V standard bridge rectifier manufactured by Taiwan Semiconductor Corporation. It utilizes a GBU molded plastic package with matte tin-plated leads for through-hole mounting. The device features a repetitive peak reverse voltage of 800 V and supports a maximum average forward current of 8 A. Peak forward surge current capability reaches 200 A under single half-sine-wave conditions. Electrical characteristics include a typical junction-to-ambient thermal resistance of 21 °C/W and a maximum junction temperature of 150 °C.

Feature Summary

• High case dielectric strength rated at 1500 VRMS
• Molding compound meets UL 94V-0 flammability rating
• Typical reverse leakage current less than 0.1 μA
• UL Recognized File # E-326243

Applications

• Switching mode power supply (SMPS)
• Adapters
• Lighting application

Procurement Notes

Verify the specific part number against official datasheets to confirm electrical ratings and package dimensions. Ensure compliance with RoHS standards and halogen-free requirements according to IEC 61249-2-21 before procurement. Confirm that the supplier provides genuine components from Taiwan Semiconductor Corporation to avoid counterfeit parts.

Selection Notes

Select the GBU806-K when an 800 V blocking voltage is required for AC to DC conversion in compact designs. Consider the GBU package size for PCB space constraints and verify thermal management needs based on the 21 °C/W junction-to-ambient resistance. Evaluate surge current requirements against the 200 A IFSM rating for circuit protection.

Part Context

This component belongs to the GBU804-K through GBU807-K series from Taiwan Semiconductor Corporation. The series offers standardized 8 A bridge rectifiers with varying reverse voltage ratings from 400 V to 1000 V. The GBU806-K specifically addresses applications requiring 800 V blocking capability within this unified package family.

Replacement Considerations

Compatible substitutes within the same series include GBU804-K (400 V), GBU805-K (600 V), and GBU807-K (1000 V). Verify voltage ratings match the specific circuit requirements when selecting alternatives.
