Taiwan Semiconductor Corporation GBU1006H

Overview

GBU1006H from Taiwan Semiconductor is a 10A, 800V AEC-Q101-qualified standard bridge rectifier in GBU package, featuring 220A surge current capability, 1500VRMS dielectric strength, and <5µA reverse leakage at 25°C. It serves as the AC-to-DC front-end in automotive-grade power supplies and lighting drivers.

For engineers reviewing the GBU1006H datasheet, GBU1006H pinout, GBU1006H application, or GBU1006H equivalent, key selection criteria include peak reverse voltage (800V), thermal resistance (R_θJC = 2°C/W), AEC-Q101 qualification status, and junction temperature range (–55°C to +150°C).

Technical Context

The GBU1006H integrates four silicon diodes in a single-phase full-wave bridge configuration with quad-anode/cathode topology. Its 800V V_RRM rating supports industrial and automotive input stages where line transients exceed 600V RMS.

Thermal performance is defined by R_θJA = 21°C/W (free air) and R_θJC = 2°C/W, enabling 10A continuous operation with minimal heatsinking when mounted on PCB copper areas ≥4 cm². Junction capacitance is 94 pF per diode at 1 MHz and 4.0 V reverse bias.

FAQ

What is the peak repetitive reverse voltage rating of the GBU1006H?

The GBU1006H has a peak repetitive reverse voltage (V_RRM) rating of 800 V. This value is confirmed in the Absolute Maximum Ratings table of the official Taiwan Semiconductor datasheet (Version M2103). It defines the maximum reverse voltage the device can withstand repeatedly without breakdown, making the GBU1006H suitable for 400VAC input-derived applications with safety margin. The GBU1006H maintains this rating across its full operating temperature range.

Is the GBU1006H AEC-Q101 qualified, and what does that mean for design use?

Yes, the GBU1006H is explicitly AEC-Q101 qualified, as indicated by the "H" suffix in its ordering code and confirmed in the FEATURES section of the datasheet. This qualification validates the device for automotive electronic components under stress conditions including temperature cycling, mechanical shock, and humidity. For designs targeting engine compartments or ADAS modules, the GBU1006H satisfies Tier-1 supplier requirements where GBU1006 (non-H) would be rejected.

What is the thermal resistance from junction to case (R_θJC) for the GBU1006H?

The junction-to-case thermal resistance (R_θJC) of the GBU1006H is 2°C/W, per the THERMAL PERFORMANCE table in the official datasheet. This low value allows efficient heat transfer from the silicon die to the PCB pad or external heatsink. When designing for 10A continuous operation, this R_θJC enables thermal management using minimal copper area or compact clip-on heatsinks-critical for space-constrained automotive and industrial layouts.

How does the GBU1006H differ from the GBU1006 in terms of packaging and marking?

The GBU1006H and GBU1006 share identical GBU package dimensions, lead finish (matte tin), and mechanical outline. The only physical difference is the marking: GBU1006H units are laser-marked with "GBU1006H" to denote AEC-Q101 qualification, while GBU1006 units display "GBU1006". Both use the same UL 94V-0 molding compound and weigh approximately 4.0 g. No PCB layout changes are needed when upgrading from GBU1006 to GBU1006H.

What is the maximum reverse leakage current (I_R) of the GBU1006H at 125°C?

At junction temperature of 125°C and rated reverse voltage, the GBU1006H exhibits a maximum reverse leakage current (I_R) of 500 µA per diode, as specified in the ELECTRICAL SPECIFICATIONS table. This value is measured under pulse test conditions (PW = 30 ms) and reflects worst-case leakage under elevated thermal stress. It remains well below thresholds that would impact efficiency in high-temperature automotive or industrial applications.
