Taiwan Semiconductor Corporation GBL02

Overview

GBL02 from Taiwan Semiconductor is a 4A, 200V repetitive peak reverse voltage (VRRM) standard bridge rectifier in GBL package, featuring glass passivated chip junctions, <1.1V forward voltage at 4A/25°C, and <5µA reverse current at 25°C. It serves as the AC-to-DC front-end in compact offline power supplies for consumer adapters.

For engineers reviewing the GBL02 datasheet, GBL02 pinout, GBL02 application, or GBL02 equivalent, key selection criteria include VRRM margin for surge tolerance, thermal resistance (RθJA = 32°C/W), junction temperature rating (150°C), and AEC-Q101 qualification availability for automotive-grade variants.

Technical Context

The GBL02 integrates four silicon diodes in a single-phase full-wave bridge configuration with common-cathode and common-anode terminals. Its glass passivation ensures stable reverse leakage (<5 µA at 25°C) and high dielectric strength under humid conditions.

Thermally, it delivers RθJC = 8°C/W to case and RθJA = 32°C/W in free-air PCB mounting, enabling 4A continuous conduction at TA ≤ 40°C without heatsink. The 150°C maximum junction temperature supports operation in enclosed industrial enclosures.

Key Specifications

Pinout & Package

GBL02 uses the GBL surface-mount package: 4-pin, single-row, gull-wing leads, 2.00g mass, UL 94V-0 molding compound, matte tin-plated terminals compliant with J-STD-002 solderability and JESD201 Class 2 whisker resistance.

Compared with GBU2K and KBP202, the GBL02 offers superior thermal performance (RθJA = 32°C/W), lower leakage (<5 µA), and UL recognition-making it optimal for compact, certified, and thermally demanding SMPS designs where reliability and regulatory compliance are prioritized.

Availability

GBL02 is available at Aetrix Electronics and suitable for switching mode power supplies, LED lighting drivers, and USB-C wall adapters requiring stable component supply, consistent parametric performance, and long-term manufacturing continuity.

Supply support for GBL02 includes scheduled delivery planning, volume procurement assistance, BOM continuity management, traceable sourcing, and lifecycle availability coordination for OEM customers, industrial embedded developers, connected-device designers, and electronics production programs.

Manufacturer

Taiwan Semiconductor Corporation (TSC) is a vertically integrated analog and discrete semiconductor manufacturer headquartered in Hsinchu, Taiwan, serving industrial, computing, and consumer markets since 1979.

The GBL02 belongs to TSC's standard bridge rectifier product line, engineered for high-reliability AC/DC front-end conversion in space-constrained, thermally demanding offline power applications.

FAQ

What is the maximum repetitive peak reverse voltage (VRRM) of the GBL02?

The GBL02 has a VRRM of 200 V, meaning it can reliably block reverse voltages up to 200 V in repetitive AC waveforms. This rating is confirmed in the Absolute Maximum Ratings table for the GBL02 specifically-not extrapolated from adjacent variants-and ensures safe operation with 100 V RMS input (141 V peak) plus margin for line surges. The GBL02 must not be substituted with lower-VRRM variants like GBL01 (100 V) in 200 V applications.

Does the GBL02 require a heatsink for 4A continuous operation?

The GBL02 sustains 4A average forward current at TC = 50°C without external heatsinking, per its Absolute Maximum Ratings. In free-air PCB mounting (RθJA = 32°C/W), it operates safely at 4A only if ambient temperature remains ≤40°C. For higher ambient or sustained 4A loads, thermal design must use copper pour or metal-core PCB to emulate case-controlled conditions-no bolt-on heatsink is defined in the datasheet for the GBL package.

Is the GBL02 RoHS and halogen-free compliant?

Yes, the GBL02 is RoHS compliant and halogen-free per IEC 61249-2-21, as explicitly stated in the FEATURES section. Its molding compound meets UL 94V-0 flammability rating, and terminals are matte tin plated and solderable per J-STD-002. These compliance attributes are verified for the GBL02 and apply to all variants in the GBL005–GBL10 family.

What is the forward voltage drop (VF) of the GBL02 at rated current?

The GBL02 exhibits a maximum forward voltage drop of 1.1 V at 4A and 25°C junction temperature, per the Electrical Specifications table. At 2A, VF is ≤1.0 V. This value reflects worst-case conduction loss across the internal diode quad and directly impacts thermal design-e.g., 4.4 W dissipation at 4A-so derating is required at elevated temperatures per the Forward Current Derating Curve.

Can the GBL02 be used in automotive applications?

The base GBL02 is not AEC-Q101 qualified, but the pin-compatible GBL02H variant is explicitly qualified per AEC-Q101. Engineers designing for automotive body electronics must specify GBL02H-not GBL02-to meet stress-test requirements for temperature cycling, humidity, and mechanical vibration. The GBL02H shares identical electrical specs and GBL package dimensions but undergoes additional qualification screening.
