Taiwan Semiconductor Corporation GBU606H

Overview

GBU606H from Taiwan Semiconductor is a 6A, 800V AEC-Q101 qualified standard bridge rectifier in GBU package, featuring 175A surge current capability, 2°C/W junction-to-case thermal resistance, and typical reverse leakage <5µA at 25°C. It serves as the AC-DC input stage in automotive-grade power adapters and industrial SMPS.

For engineers reviewing the GBU606H datasheet, GBU606H pinout, GBU606H application, or GBU606H equivalent, key selection criteria include peak reverse voltage (800V), forward current rating (6A), AEC-Q101 qualification status, thermal resistance (R_θJC = 2°C/W), and junction capacitance (94pF).

Technical Context

This quad-diode bridge integrates four silicon PN junctions in a single-phase full-wave configuration with common-cathode and common-anode terminals. Its internal layout supports high-reliability operation under repetitive surge conditions (IFSM = 175A, t = 8.3ms) and maintains stable reverse blocking up to 800V V_RRM.

The device uses matte tin-plated leads compliant with J-STD-002 solderability standards and achieves 1500V_RMS dielectric strength between case and terminals. Thermal performance is defined by R_θJA = 21°C/W and R_θJC = 2°C/W, enabling direct heatsink mounting for high-power density designs.

FAQ

What is the peak repetitive reverse voltage rating of the GBU606H?

The GBU606H has a peak repetitive reverse voltage (V_RRM) rating of 800 V. This value is specified in the Absolute Maximum Ratings table of the official Taiwan Semiconductor datasheet (Version N2103). The 800 V rating applies specifically to the GBU606H variant and distinguishes it from other members of the GBU601–GBU607 family, such as GBU605 (600 V) and GBU607 (1000 V). This parameter defines the maximum AC voltage the device can block during normal operation without risk of avalanche breakdown.

Is the GBU606H qualified to AEC-Q101 standards?

Yes, the GBU606H is explicitly AEC-Q101 qualified, as confirmed in the FEATURES section and ORDERING INFORMATION notes of the Taiwan Semiconductor datasheet. The "H" suffix in GBU606H denotes AEC-Q101 qualification, which includes stress testing for temperature cycling, high-temperature reverse bias (HTRB), and electrostatic discharge (ESD). This makes the GBU606H suitable for automotive applications where component reliability under thermal, mechanical, and electrical stress is mandatory.

What is the junction-to-case thermal resistance of the GBU606H?

The junction-to-case thermal resistance (R_θJC) of the GBU606H is 2 °C/W, as published in the THERMAL PERFORMANCE section of the official datasheet. This value is measured under standard test conditions and reflects the efficiency of heat conduction from the silicon die to the outer case surface. A low R_θJC enables effective thermal coupling to an external heatsink, allowing the GBU606H to sustain its full 6 A forward current rating at higher ambient temperatures when properly mounted.

Does the GBU606H meet RoHS and halogen-free requirements?

Yes, the GBU606H is RoHS compliant and halogen-free in accordance with IEC 61249-2-21, as stated in the FEATURES section of the Taiwan Semiconductor datasheet. The halogen-free designation applies to the molding compound and internal materials, and RoHS compliance covers restriction of lead, mercury, cadmium, hexavalent chromium, PBB, and PBDE. These certifications are verified through material declarations and third-party testing, supporting compliance in EU, China, and other regulated markets.

What is the typical junction capacitance of the GBU606H?

The typical junction capacitance (C_J) of the GBU606H is 94 pF per diode, measured at 1 MHz and 4.0 V reverse bias, as specified in the ELECTRICAL SPECIFICATIONS table for GBU605–GBU607 variants. This value is lower than earlier family members (e.g., GBU601–GBU604 at 211 pF), resulting in reduced high-frequency switching noise and improved EMI performance in fast-switching AC-DC converters using the GBU606H.
