Taiwan Semiconductor Corporation GBL005

Overview

GBL005 from Taiwan Semiconductor is a 4A, 50V repetitive peak reverse voltage (VRRM) standard quad bridge rectifier with glass passivated junctions, UL Recognized (E-326243), RoHS- and halogen-free compliant, designed for PCB mounting in compact AC/DC power conversion stages.

For engineers reviewing the GBL005 datasheet, GBL005 pinout, GBL005 application, or GBL005 equivalent, key selection factors include its 150A surge rating (IFSM), 13°C/W junction-to-lead thermal resistance, 1.1V max forward voltage at 4A/25°C, and AEC-Q101 qualification availability - critical for reliability-critical SMPS and lighting designs.

Technical Context

The GBL005 integrates four silicon diodes in a single-phase full-wave bridge configuration housed in a GBL molded package. Its glass passivated junction ensures stable reverse leakage (<5 µA at 25°C) and high dielectric strength, while the matte tin-plated leads meet J-STD-002 solderability and JESD201 Class 2 whisker resistance requirements.

Thermally, it delivers R_θJL = 13°C/W and R_θJC = 8°C/W, enabling operation up to T_J = 150°C. Junction capacitance is 95 pF per diode at 1 MHz/4 V, optimized for switching frequencies typical in offline adapters and LED drivers.

FAQ

What is the maximum junction temperature rating for GBL005?

The GBL005 has a maximum junction temperature (T_J) of +150°C, verified per absolute maximum ratings in the official Taiwan Semiconductor datasheet (Version K2103). This rating applies under steady-state conditions with appropriate thermal management - such as mounting on ≥0.5"×0.5" copper pads or using a heatsink. Exceeding this limit risks irreversible degradation of the glass-passivated junction.

Does GBL005 support automotive applications?

The standard GBL005 is not AEC-Q101 qualified, but Taiwan Semiconductor offers the GBL005H variant - identical electrically and mechanically, with added AEC-Q101 stress testing for automotive use. For automotive-grade deployment, specify GBL005H; the base GBL005 remains suitable for industrial and commercial applications meeting IEC/UL safety standards.

What is the forward voltage drop of GBL005 at full rated current?

The GBL005 exhibits a maximum forward voltage (V_F) of 1.1 V at I_F = 4 A and T_J = 25°C, per the Electrical Specifications table. At elevated junction temperatures (e.g., 125°C), V_F decreases slightly due to semiconductor physics, but the 1.1 V value represents the worst-case conduction loss used for thermal and efficiency calculations in the GBL005 design.

Is GBL005 lead-free and RoHS compliant?

Yes, the GBL005 is fully RoHS compliant and halogen-free per IEC 61249-2-21. Its matte tin-plated leads are lead-free, and the molding compound meets UL 94V-0 flammability requirements. Taiwan Semiconductor confirms compliance in the product documentation (Version K2103), and the device carries the RoHS marking on packaging and datasheet.

What does the "GBL" in GBL005 signify?

The "GBL" prefix in GBL005 denotes the package type - a 4-terminal, single-phase bridge rectifier in a molded plastic case with standardized dimensions and terminal layout defined by Taiwan Semiconductor. It is distinct from GBU, KBP, or DB packages and indicates compatibility with specific footprint and thermal mounting guidelines outlined in the GBL Package Outline Drawing.
