Taiwan Semiconductor Corporation GBU1003HD2G

Overview

GBU1003HD2G from Taiwan Semiconductor is a 10A, 200V AEC-Q101-qualified standard bridge rectifier in GBU package, featuring 220A surge current capability, 1500VRMS dielectric strength, and typical reverse leakage <5µA at 25°C - used in automotive-grade AC/DC front-end stages of lighting drivers and SMPS.

For engineers reviewing the GBU1003HD2G datasheet, GBU1003HD2G pinout, GBU1003HD2G application, or GBU1003HD2G equivalent, key selection criteria include VRRM=200V, IFSM=220A, RθJC=2°C/W, TJ max=150°C, and AEC-Q101 qualification for under-hood power conversion designs.

Technical Context

This quad-diode bridge rectifier integrates four silicon junction diodes in a single-phase full-wave configuration with common-cathode/common-anode topology. It supports continuous 10A forward current and withstands repetitive 200V reverse voltage (VRRM), with thermal resistance RθJC = 2°C/W enabling efficient heat transfer to heatsink-mounted PCBs.

Designed for high-reliability automotive environments, GBU1003HD2G meets AEC-Q101 stress testing requirements and features matte tin-plated leads compliant with J-STD-002 solderability, UL 94V-0 molding compound, and halogen-free construction per IEC 61249-2-21.

FAQ

What is the peak repetitive reverse voltage rating of GBU1003HD2G?

The GBU1003HD2G has a peak repetitive reverse voltage (VRRM) rating of 200 V. This value is specified in the Absolute Maximum Ratings table of the official Taiwan Semiconductor datasheet (Version M2103) and defines the maximum AC or DC reverse voltage the device can block repeatedly without breakdown. It is critical for ensuring safe operation in 120VAC or 230VAC-derived circuits where peak line voltage reaches ~170V or ~325V respectively, requiring adequate derating margin.

Is GBU1003HD2G qualified to AEC-Q101 standards?

Yes, GBU1003HD2G is explicitly AEC-Q101 qualified, as confirmed by the "H" suffix in its ordering code and documented in the FEATURES section of the Taiwan Semiconductor datasheet. This qualification covers stress tests including temperature cycling, high-temperature operating life, and unbiased highly accelerated stress testing - making GBU1003HD2G suitable for automotive power electronics such as headlamp drivers and body control modules.

What does the "D2G" suffix mean in GBU1003HD2G?

The "D2G" suffix in GBU1003HD2G indicates tape-and-reel packaging (D2) and green (halogen-free) molding compound (G), per Taiwan Semiconductor's ordering nomenclature. D2 denotes 20-piece/reel packaging in embossed carrier tape, while G confirms compliance with IEC 61249-2-21 halogen-free requirements - both essential for automated SMT assembly and environmental compliance in automotive and industrial manufacturing.

What is the thermal resistance from junction to case for GBU1003HD2G?

The junction-to-case thermal resistance (RθJC) of GBU1003HD2G is 2°C/W, as published in the THERMAL PERFORMANCE section of the datasheet. This low value enables effective heat transfer from the silicon die to the external heatsink or metal-core PCB, supporting continuous 10A operation at elevated ambient temperatures when properly mounted - a key advantage over higher-RθJC alternatives in space-constrained power designs.

Can GBU1003HD2G replace GBU1004HD2G in an existing design?

No, GBU1003HD2G cannot directly replace GBU1004HD2G without design review, because their peak repetitive reverse voltage ratings differ: GBU1003HD2G is rated at 200V VRRM, while GBU1004HD2G is rated at 400V. Substituting the lower-voltage part risks premature breakdown under 400V-rated conditions. Verify actual circuit peak reverse stress before substitution; if below 200V, GBU1003HD2G may be acceptable, but derating and safety certification must be re-evaluated.
