Taiwan Semiconductor Corporation GBU1002H

Overview

GBU1002H from Taiwan Semiconductor is a 10A, 100V AEC-Q101-qualified standard bridge rectifier in GBU package, featuring 220A surge current capability, 1500VRMS dielectric strength, and typical reverse leakage <0.1μA at 25°C - used in automotive-grade AC/DC front-ends and industrial SMPS.

For engineers reviewing the GBU1002H datasheet, GBU1002H pinout, GBU1002H application, or GBU1002H equivalent, key selection criteria include peak reverse voltage (100V), thermal resistance (R_θJC = 2°C/W), junction temperature range (–55°C to +150°C), and AEC-Q101 qualification status for automotive reliability validation.

Technical Context

The GBU1002H integrates four silicon diodes in a single-phase full-wave bridge configuration with quad-terminal layout (AC1, AC2, +, –). It operates within a junction temperature range of –55°C to +150°C and delivers 10A average forward current with 220A non-repetitive surge rating (8.3ms half-sine).

Thermal performance is defined by R_θJA = 21°C/W (free-air) and R_θJC = 2°C/W (case), enabling high-power density mounting on PCBs. Reverse recovery behavior is not specified; it is optimized for line-frequency rectification rather than high-frequency switching.

Manufacturer

Taiwan Semiconductor Corporation (TSC) is a vertically integrated analog and discrete semiconductor manufacturer headquartered in Hsinchu, Taiwan, serving global industrial, automotive, and consumer markets since 1979.

The GBU series was developed for high-reliability AC/DC front-end applications demanding robust surge immunity, low leakage, and extended temperature operation - especially where space-constrained PCB layouts require quad-terminal bridge integration.

FAQ

What is the peak repetitive reverse voltage rating of the GBU1002H?

The GBU1002H has a peak repetitive reverse voltage (V_RRM) rating of 100 V. This value defines the maximum AC voltage the device can block during normal operation without breakdown. It corresponds to a maximum RMS input voltage of approximately 70 V, making the GBU1002H suitable for low-voltage AC inputs such as 24–48 VAC control circuits or auxiliary windings in multi-output power supplies.

Is the GBU1002H pin-compatible with other GBU-series rectifiers?

Yes, the GBU1002H shares the identical GBU package outline and quad-terminal pinout (AC1, AC2, +, –) with all members of the GBU1001–GBU1007 family, including GBU1001H through GBU1007H. Mechanical and soldering compatibility is maintained across the series, enabling layout reuse when upgrading V_RRM or selecting AEC-Q101 variants like the GBU1002H.

Does the GBU1002H meet RoHS and halogen-free requirements?

Yes, the GBU1002H is RoHS compliant and halogen-free per IEC 61249-2-21. The molding compound is UL 94V-0 rated, and the matte tin-plated leads meet J-STD-002 solderability standards. These certifications are confirmed in the official Taiwan Semiconductor datasheet revision M2103 and apply specifically to the "H" suffix variant, including the GBU1002H.

What is the maximum junction temperature for continuous operation of the GBU1002H?

The GBU1002H supports a maximum junction temperature (T_J) of +150°C for continuous operation, with a storage temperature range of –55°C to +150°C. This rating enables reliable use in high-ambient environments such as automotive engine compartments or sealed industrial enclosures, provided thermal design maintains junction temperature below this limit using the specified R_θJC = 2°C/W path.

How does the AEC-Q101 qualification impact the use of the GBU1002H?

The AEC-Q101 qualification confirms that the GBU1002H has passed rigorous stress tests including temperature cycling, high-temperature reverse bias (HTRB), and electrostatic discharge - required for automotive electronic components. This makes the GBU1002H suitable for under-hood and chassis-mounted applications where reliability under thermal and mechanical stress is critical, unlike standard GBU1002 which lacks this validation.
