Taiwan Semiconductor Corporation GBL202

Overview

GBL202 from Taiwan Semiconductor is a 2A, 100V standard bridge rectifier in GBL package, featuring glass-passivated junctions, <1μA reverse leakage at 25°C, and 60A surge rating - used in AC/DC front-end stages of compact SMPS and LED drivers.

For engineers reviewing the GBL202 datasheet, GBL202 pinout, GBL202 application, or GBL202 equivalent, key selection criteria include VRRM=100V, IF=2A, VF≤1.0V @2A, RθJA=32°C/W, and AEC-Q101 qualification availability (GBL202H variant).

Technical Context

The GBL202 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 across -55°C to +150°C operating range and supports high dielectric strength for isolation-critical power supplies.

Designed for PCB mounting with matte tin-plated leads compliant with J-STD-002, the device delivers 14.9 A²s fusing rating under 8.3ms half-sine surge and exhibits typical junction capacitance of 25pF per diode at 1MHz/4V.

Equivalent & Alternatives

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

Compared with GBL202, GBU2A offers lower cost but insufficient VRRM for universal-input SMPS, while DF02MA provides higher voltage rating and same package compatibility at the expense of slightly elevated conduction loss and missing automotive qualification.

FAQ

What is the maximum junction temperature rating for GBL202?

The GBL202 has a maximum junction temperature (TJ MAX) of +150°C, verified per absolute maximum ratings table. This allows operation in high-ambient environments such as enclosed LED drivers or industrial control cabinets. Derating curves in the datasheet specify usable current vs. ambient temperature, and thermal design must ensure RθJA × (Pdissipated) + TA ≤ 150°C. The GBL202 achieves this with its 32°C/W RθJA and low VF conduction loss.

Does GBL202 have AEC-Q101 qualification?

The base GBL202 is not AEC-Q101 qualified; however, the GBL202H variant - indicated by the "H" suffix in the ordering code - is fully AEC-Q101 qualified per Version J2103 documentation. This qualification covers temperature cycling, humidity testing, and mechanical shock, making GBL202H suitable for automotive infotainment and body electronics power supplies where reliability under extended thermal stress is mandatory.

What is the forward voltage drop specification for GBL202 at rated current?

The GBL202 has a maximum forward voltage drop (VF) of 1.0 V per diode at IF = 2 A and TJ = 25°C, measured under pulsed conditions (PW = 0.3 ms). This value reflects worst-case conduction loss across the bridge - totaling ≤2.0 V drop across both conducting diodes in series during each half-cycle. Real-world VF increases with junction temperature, reaching ~1.1 V at 125°C, as confirmed in the typical forward characteristics curve.

How does the GBL202 compare to GBL201 and GBL203 in terms of voltage rating?

The GBL202 is rated for 100 V repetitive peak reverse voltage (VRRM), positioned between GBL201 (50 V) and GBL203 (200 V) in the GBL201–GBL207 family. Its 100 V rating supports 70 V RMS input - sufficient for 100 VAC nominal grids and 85–265 VAC universal-input designs with appropriate derating. Unlike GBL201, it avoids overvoltage risk in 120 VAC regions; unlike GBL203, it maintains lower junction capacitance (25 pF) and tighter VF consistency.

What packaging and taping options are available for GBL202?

The GBL202 is supplied in tube packaging with 25 units per tube, as specified in the ordering information section. Both standard (GBL202) and AEC-Q101 qualified (GBL202H) versions use identical GBL molded package and tube format. Tape-and-reel is not listed in the official documentation for this part number; alternative packaging requires custom quoting and may impact lead time and minimum order quantity.
