Taiwan Semiconductor Corporation GBL01H

Overview

GBL01H from Taiwan Semiconductor is a 4A, 100V AEC-Q101-qualified standard bridge rectifier in GBL package, featuring glass-passivated junctions, 150A surge rating, and <0.1μA typical reverse leakage at 25°C - used in automotive-grade AC/DC front-ends and lighting power supplies.

For engineers reviewing the GBL01H datasheet, GBL01H pinout, GBL01H application, or GBL01H equivalent, key selection criteria include repetitive peak reverse voltage (100 V), forward current rating (4 A at TC = 50°C), thermal resistance (R_θJL = 13 °C/W), and AEC-Q101 qualification for under-hood reliability.

Technical Context

The GBL01H integrates four silicon diodes in a single-phase full-wave bridge configuration with quad internal layout, enabling direct AC-to-DC conversion without external interconnects. Its glass-passivated junction ensures stable reverse characteristics across temperature and humidity stress.

Designed for surface-mount PCB assembly, it supports soldering per J-STD-002 and meets JESD201 Class 2 whisker resistance. The GBL package provides UL 94V-0 flammability compliance and 2.00 g mass for mechanical stability in vibration-prone environments.

Key Specifications

Pinout & Package

GBL01H uses the industry-standard GBL package: molded plastic case with 4 matte tin-plated leads, UL 94V-0 rated compound, and polarity marked on top surface. Dimensions conform to Taiwan Semiconductor's GBL outline drawing (Version K2103).

Equivalent & Alternatives

The following parts are listed as comparable options for similar bridge rectifier applications.

Compared with GBU4K and DF04M, the GBL01H uniquely combines AEC-Q101 qualification, 13 °C/W junction-to-lead thermal resistance, and <5 µA reverse leakage - making it the only option qualified for automotive front-end rectification with minimal PCB thermal overhead.

Availability

GBL01H is available at Aetrix Electronics and suitable for automotive lighting systems, industrial AC-DC adapters, and commercial LED ballasts requiring stable component supply, long-lifecycle assurance, and AEC-Q101-compliant sourcing.

Supply support for GBL01H 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, specializing in rectifiers, TVS diodes, MOSFETs, and bipolar transistors since 1979.

The GBL series was developed specifically for high-reliability AC/DC conversion in automotive and industrial power supplies, emphasizing thermal robustness, low leakage, and qualification-ready packaging.

FAQ

What is the maximum junction temperature rating for GBL01H?

The GBL01H has a maximum junction temperature (T_J) of +150°C, verified per absolute maximum ratings in the K2103 datasheet. This rating enables operation in under-hood automotive environments and enclosed LED drivers. Thermal design must maintain junction temperature below this limit using the specified R_θJL = 13 °C/W path to PCB copper. The GBL01H achieves this while sustaining 4 A forward current at T_C = 50°C.

Is GBL01H pin-compatible with other GBL-series rectifiers like GBL02H or GBL04H?

Yes, all GBL-series devices including GBL01H, GBL02H, and GBL04H share identical GBL package dimensions, lead count, pinout (AC1, AC2, +, –), and mounting footprint. Voltage ratings differ (100 V vs. 200 V vs. 400 V), but mechanical and electrical interface compatibility is maintained across the family. The GBL01H can be substituted in layouts designed for higher-voltage variants when system requirements allow reduced V_RRM.

Does GBL01H meet halogen-free and RoHS requirements?

Yes, GBL01H complies with both RoHS Directive 2011/65/EU and IEC 61249-2-21 halogen-free standards. The molding compound contains no brominated flame retardants or chlorine-based additives, and lead content is below 1000 ppm. This is confirmed in the K2103 revision documentation and supported by Taiwan Semiconductor's material declarations. GBL01H is fully compliant for use in eco-regulated markets.

What is the surge current rating of GBL01H and how is it tested?

The GBL01H supports a non-repetitive peak forward surge current (I_FSM) of 150 A, tested per JEDEC JESD201 with an 8.3 ms single half-sine waveform superimposed on rated load. This rating ensures robustness against inrush currents during cold start in lighting and adapter applications. The GBL01H maintains this capability across its full operating temperature range, with no derating required up to T_J = 125°C.

How does the AEC-Q101 qualification of GBL01H impact its use in automotive designs?

The AEC-Q101 qualification of GBL01H validates performance across temperature cycling, high-temperature reverse bias, and mechanical shock tests required for automotive under-hood and cabin applications. It eliminates need for additional qualification testing by Tier 1 suppliers. GBL01H is approved for use in LED headlamps, body control modules, and infotainment power supplies where reliability over 15+ years is mandated - unlike non-qualified alternatives such as standard GBL01.
