Taiwan Semiconductor Corporation GBL01

Overview

GBL01 from Taiwan Semiconductor is a 4A, 100V standard bridge rectifier in GBL package, featuring glass-passivated junctions, <1.1V forward voltage at 4A/25°C, <5µA reverse leakage at 25°C, and 150A surge rating - used in AC/DC front-ends of compact SMPS and LED drivers.

For engineers reviewing the GBL01 datasheet, GBL01 pinout, GBL01 application, or GBL01 equivalent, key selection criteria include peak reverse voltage (100V), thermal resistance (R_θJL = 13°C/W), AEC-Q101 qualification availability, UL recognition (E-326243), and compatibility with J-STD-002 soldering standards.

Technical Context

The GBL01 integrates four silicon diodes in a single-phase full-wave bridge configuration with common-cathode/common-anode topology. Its glass-passivated junction ensures stable reverse characteristics up to 125°C, and its 13°C/W junction-to-lead thermal resistance supports conduction-cooled PCB mounting without heatsinks at ≤3A continuous operation.

Rated for 100V repetitive peak reverse voltage (V_RRM) and 70V RMS reverse voltage (V_R(RMS)), the device delivers 4A average forward current at T_C = 50°C and maintains <500µA IR at 125°C - enabling reliable operation in thermally constrained lighting and adapter designs.

Key Specifications

Pinout & Package

Compared with GBU1K and KBU4B, the GBL01 uniquely balances 4A current handling, 100V V_RRM, UL recognition, and 13°C/W thermal resistance - making it optimal for compact, certified, medium-power AC/DC converters where thermal headroom and regulatory alignment are critical.

Availability

GBL01 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 lead-time visibility, and traceable sourcing.

Supply support for GBL01 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

FAQ

What is the maximum average forward current rating for GBL01 at ambient temperature?

The GBL01 is rated for 3A average forward current at T_A = 40°C with free-air convection. At T_C = 50°C (case temperature), its rating increases to 4A. This distinction is critical: PCB copper pad area and thermal vias directly impact whether the 4A rating applies. For GBL01, sustained 4A operation requires adequate copper thermal mass or heatsinking per the datasheet's 0.5"x0.5" pad recommendation.

Does GBL01 have AEC-Q101 qualification?

The base GBL01 is not AEC-Q101 qualified; however, the AEC-Q101-compliant variant is explicitly designated as GBL01H per Taiwan Semiconductor's ordering code table. GBL01H shares identical electrical and thermal specs but undergoes additional stress testing for automotive applications. Always verify the "H" suffix in the orderable part number when targeting automotive use cases.

What is the reverse recovery time (t_rr) of GBL01?

Taiwan Semiconductor does not specify reverse recovery time (t_rr) for the GBL01 because it is a standard (non-fast-recovery) silicon bridge rectifier. Its design prioritizes low leakage and thermal robustness over switching speed. For high-frequency SMPS (>100kHz), fast-recovery alternatives like GBU1J or FRED-based bridges should be evaluated instead of relying on GBL01.

Can GBL01 replace GBL005 in a 50V design?

No - GBL01 is not a drop-in replacement for GBL005. Although both share the GBL package and pinout, GBL005 has a 50V V_RRM while GBL01 is rated for 100V. Using GBL01 in a 50V-design context introduces unnecessary voltage overhead and may affect thermal behavior due to differing junction capacitance (95pF vs. ~40pF in higher-voltage variants). Select the exact voltage grade matching the circuit's reverse stress requirement.

What is the marking code visible on the GBL01 package?

The GBL01 is laser-marked with "GBL01" on the top surface of the GBL package, along with green compound indicator "G", factory code "F", and date code "YWW". This marking aligns with Taiwan Semiconductor's standard GBL-series labeling per Version K2103 documentation and confirms authenticity during incoming inspection.
