Taiwan Semiconductor Corporation GBL201

Overview

GBL201 from Taiwan Semiconductor is a 2A, 50V standard bridge rectifier in GBL package with quad configuration, glass-passivated junctions, and UL Recognized (E-326243) construction; it delivers ≤1V forward voltage at 2A and <0.1μA reverse leakage at 25°C, used in AC/DC front-end stages of compact SMPS and LED drivers.

For engineers reviewing the GBL201 datasheet, GBL201 pinout, GBL201 application, or GBL201 equivalent, key selection criteria include repetitive peak reverse voltage (50V), surge current rating (60A), thermal resistance (R_θJL = 13°C/W), AEC-Q101 qualification availability, and RoHS/halogen-free compliance per IEC 61249-2-21.

Technical Context

The GBL201 integrates four silicon diodes in a single-phase full-wave bridge configuration, enabling direct AC-to-DC conversion without external interconnection. Its glass-passivated junction ensures stable reverse characteristics across temperature and long-term reliability under repeated surge stress.

With a maximum junction temperature of 150°C and R_θJA = 32°C/W, the GBL201 supports continuous 2A conduction in PCB-mounted applications where ambient temperatures remain ≤75°C; its 14.9 A²s fusing rating defines safe single-pulse energy handling under 8.3ms half-sine surges.

FAQ

What is the maximum repetitive peak reverse voltage rating for GBL201?

The GBL201 has a maximum repetitive peak reverse voltage (V_RRM) of 50 V. This value is fixed for the GBL201 variant and defines the highest AC peak voltage the device can block during normal operation without entering avalanche breakdown. It is confirmed in the Absolute Maximum Ratings table of the official Taiwan Semiconductor datasheet (Version J2103). Exceeding this rating risks irreversible junction damage.

Does GBL201 have AEC-Q101 qualification?

The base GBL201 is not AEC-Q101 qualified, but the GBL201H variant is explicitly listed as AEC-Q101 qualified in the Ordering Information section. The "H" suffix denotes automotive-grade reliability testing including temperature cycling, high-temperature reverse bias, and electrostatic discharge robustness. For automotive applications, GBL201H must be specified; standard GBL201 is intended for industrial and consumer use.

What is the forward voltage drop of GBL201 at rated current?

The GBL201 exhibits a maximum forward voltage (V_F) of 1.0 V per diode at I_F = 2 A and T_J = 25°C, as specified in the Electrical Specifications table. This value represents worst-case conduction loss under pulsed test conditions (PW = 0.3 ms). At elevated junction temperatures or lower currents, V_F decreases slightly, but design calculations should use 1.0 V to ensure margin.

How does the GBL201 package differ from GBU or KBU packages?

The GBL201 uses the GBL package-a compact, molded plastic body with 4 gull-wing leads optimized for surface-mount assembly. Compared to the through-hole GBU package (larger footprint, higher R_θJA = 45°C/W) or the larger KBU package, GBL offers lower thermal resistance (R_θJL = 13°C/W), tighter dimensional control, and compatibility with automated pick-and-place. Its 2.00g weight and UL 94V-0 rating further distinguish it for high-density PCB layouts.

What is the surge current capability of GBL201 and how is it tested?

The GBL201 supports a non-repetitive peak forward surge current (I_FSM) of 60 A for an 8.3 ms single half-sine waveform, as defined in JEDEC standards. This rating is validated under worst-case thermal conditions (T_A = 25°C) and corresponds to a fusing I²t of 14.9 A²s. It ensures robustness against line transients and capacitor inrush during power-up, provided the surge interval allows sufficient junction cooling between events.
