Taiwan Semiconductor Corporation GBL201H

Overview

GBL201H from Taiwan Semiconductor is a 2A, 50V AEC-Q101-qualified standard bridge rectifier in GBL package, featuring glass-passivated junctions, <0.1μA typical reverse leakage at 25°C, and 13°C/W junction-to-lead thermal resistance. It delivers full-wave AC-to-DC conversion for compact power supplies in automotive-grade lighting and adapters.

For engineers reviewing the GBL201H datasheet, GBL201H pinout, GBL201H application, or GBL201H equivalent, key selection criteria include peak repetitive reverse voltage (50 V), forward current rating (2 A), surge capability (60 A @ 8.3 ms), thermal resistance (13°C/W), and AEC-Q101 qualification status.

Technical Context

The GBL201H integrates four silicon diodes in a single-phase bridge configuration with common-cathode/common-anode topology, enabling full-wave rectification without external interconnects. Its glass-passivated junction ensures stable reverse characteristics across temperature and long-term reliability under cyclic thermal stress.

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

FAQ

What is the peak repetitive reverse voltage rating for GBL201H?

The GBL201H has a peak repetitive reverse voltage (VRRM) rating of 50 V. This value is specified in the Absolute Maximum Ratings table of the official Taiwan Semiconductor datasheet (Version J2103). It defines the maximum AC input voltage peak the device can block continuously without avalanche breakdown. Exceeding this voltage risks irreversible junction damage.

Is GBL201H suitable for automotive applications?

Yes, GBL201H is explicitly AEC-Q101 qualified, as confirmed by its "H" suffix in the ordering code and documentation on page 1 of the Taiwan Semiconductor datasheet. This qualification covers stress tests including temperature cycling, high-temperature reverse bias, and electrostatic discharge-making GBL201H suitable for under-hood and cabin automotive power systems such as LED headlamps and body control modules.

What is the forward voltage drop of GBL201H at rated current?

The GBL201H exhibits a maximum forward voltage drop (VF) of 1.0 V per diode at IF = 2 A and TJ = 25°C, as stated in the Electrical Specifications table. Since the bridge contains two diodes conducting in series during each half-cycle, the total forward drop across the bridge is ≤2.0 V under those conditions-critical for calculating conduction losses in power supply efficiency analysis.

Does GBL201H require heatsinking in typical applications?

GBL201H does not require an external heatsink in most 2 A continuous applications due to its low RθJL of 13°C/W and ability to transfer heat through its leads into PCB copper. However, thermal design must verify junction temperature remains below 150°C using actual ambient conditions, airflow, and PCB copper area. For sustained 2 A loads above 60°C ambient, increasing thermal pad size or adding local copper pours is recommended.

What packaging and plating specifications apply to GBL201H?

GBL201H uses the GBL molded package with matte tin-plated leads, fully compliant with J-STD-002 for solderability. The molding compound meets UL 94V-0 flammability rating, and the device passes JESD201 Class 2 whisker testing. Lead finish and mechanical construction are documented in the Mechanical Data section of the Taiwan Semiconductor datasheet (Version J2103).
