Taiwan Semiconductor Corporation GBL02H

Overview

GBL02H from Taiwan Semiconductor is a 4A, 200V AEC-Q101-qualified 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 automotive-grade AC/DC front-ends for lighting and adapters.

For engineers reviewing the GBL02H datasheet, GBL02H pinout, GBL02H application, or GBL02H equivalent, key selection criteria include peak reverse voltage (200V), thermal resistance (R_θJL = 13°C/W), AEC-Q101 qualification status, and UL recognition (E-326243) for safety-critical power conversion designs.

Technical Context

The GBL02H 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-reliability mounting on PCBs with 0.5"×0.5" copper pads.

Thermal performance is defined by R_θJC = 8°C/W and R_θJA = 32°C/W, enabling 4A continuous conduction at T_C = 50°C without heatsink. Reverse recovery is not specified; device operates as a standard (non-fast) rectifier with typical C_J = 95pF per diode at 1MHz/4V.

FAQ

What is the peak repetitive reverse voltage rating of the GBL02H?

The GBL02H has a peak repetitive reverse voltage (V_RRM) rating of 200 V. This value defines the maximum AC voltage the device can block during normal operation without entering avalanche breakdown. It is measured across the AC input terminals with respect to the DC output terminals and is validated per JEDEC standards. The GBL02H's 200 V rating makes it suitable for 120 VAC mains applications with safety margin against line surges.

Is the GBL02H qualified to AEC-Q101 standards?

Yes, the GBL02H is explicitly AEC-Q101 qualified, as indicated by the "H" suffix in its ordering code. This qualification covers stress tests including high-temperature operating life, temperature cycling, and unbiased highly accelerated stress testing. The GBL02H's AEC-Q101 status is documented in Taiwan Semiconductor's official qualification report K2103 and enables use in automotive power modules, LED lighting controllers, and body electronics where reliability under harsh conditions is mandatory.

What is the forward voltage drop of the GBL02H at rated current?

The GBL02H exhibits a maximum forward voltage drop (V_F) of 1.1 V per diode at 4 A and 25°C junction temperature. Since the device contains four diodes in bridge configuration, two conduct simultaneously during each half-cycle, resulting in ~2.2 V total conduction drop across the bridge. This value directly impacts conduction losses and thermal design - for example, at 4 A continuous, power dissipation is approximately 4.4 W under worst-case V_F.

Does the GBL02H have UL safety recognition?

Yes, the GBL02H carries UL Recognition under file number E-326243. This certification confirms compliance with UL 60747-4 for semiconductor devices and validates its dielectric strength, flammability rating (UL 94V-0), and construction integrity. UL recognition simplifies end-product safety approvals for power supplies targeting North American markets and is maintained across all GBLxH variants in the family.

What is the thermal resistance from junction to lead (R_θJL) for the GBL02H?

The GBL02H has a typical junction-to-lead thermal resistance (R_θJL) of 13°C/W. This parameter reflects heat transfer efficiency from the silicon die to the soldered lead terminations and is critical for estimating solder-joint temperature rise and long-term reliability. When mounted on a PCB with adequate copper area (e.g., 0.5"×0.5" pads), this R_θJL enables the GBL02H to sustain 4 A average current at case temperature ≤50°C without external heatsinking.
