Taiwan Semiconductor Corporation GBL10H

Overview

GBL10H from Taiwan Semiconductor is a 4A, 1000V 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 SMPS and lighting power supplies.

For engineers reviewing the GBL10H datasheet, GBL10H pinout, GBL10H application, or GBL10H equivalent, key selection criteria include peak reverse voltage (1000V), thermal resistance (R_θJL = 13°C/W), AEC-Q101 qualification status, junction capacitance (40pF), and UL recognition (E-326243).

Technical Context

The GBL10H integrates four silicon diodes in a single-phase full-wave bridge configuration with quad anode-cathode topology. Its glass-passivated junction ensures stable reverse characteristics up to 125°C and supports high-reliability operation in automotive ambient conditions.

Thermal performance is defined by R_θJC = 8°C/W and R_θJL = 13°C/W, enabling direct PCB mounting on 0.5"×0.5" copper pads or heatsink mounting per Fig.1 derating curve. Junction temperature range is −55°C to +150°C.

Key Specifications

Pinout & Package

GBL10H uses the GBL molded plastic package (UL 94V-0 rated), with 4 terminals arranged in standard bridge configuration: two AC input pins (marked ~) and one DC+ (anode common) and one DC− (cathode common) output pin. Polarity is marked on top surface per datasheet diagram.

Supply support for GBL10H 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 power ICs since 1979.

The GBL series was developed specifically for high-reliability AC/DC front-end applications demanding AEC-Q101 compliance, UL safety recognition, and robust thermal performance in compact GBL packaging.

FAQ

What does the "H" suffix in GBL10H signify?

The "H" suffix in GBL10H indicates AEC-Q101 qualification per JESD22-A108 stress testing standards. This certification confirms the device meets automotive-grade reliability requirements for temperature cycling, high-temperature reverse bias, and unbiased high-temperature storage - a distinction not present in the base GBL10 variant. GBL10H is fully tested and documented to this standard by Taiwan Semiconductor.

Is GBL10H compatible with lead-free reflow soldering processes?

Yes, GBL10H features matte tin-plated leads qualified to J-STD-002 for solderability and passes JESD201 Class 2 whisker testing. It supports standard lead-free reflow profiles (peak temperature ≤260°C, time above 217°C ≤60 seconds) without degradation of electrical or mechanical performance.

What is the maximum allowable ambient temperature for GBL10H at 4A continuous current?

At 4A continuous forward current, GBL10H must be operated with case temperature limited to 50°C per datasheet derating curves. With R_θJA = 32°C/W, the maximum ambient temperature is approximately 34°C when mounted on standard PCB copper pads - requiring heatsinking or forced air cooling for higher ambient environments.

Does GBL10H require external snubber circuits in typical SMPS applications?

GBL10H's 40pF junction capacitance and glass-passivated construction provide inherent noise suppression, and its 1000V V_RRM margin typically eliminates the need for external snubbers in 277V/400V AC-input SMPS. However, snubbers remain recommended for systems subject to severe line transients exceeding IEC 61000-4-5 Level 4.

How is polarity marked on the GBL10H package?

Polarity on GBL10H is marked on the top surface of the GBL package: the "+" symbol identifies the DC output anode terminal, "−" marks the cathode terminal, and "~" symbols mark both AC input terminals. The marking layout follows the standard GBL outline diagram in Taiwan Semiconductor's K2103 datasheet revision.
