Product details
Overview
GBU15L05H from Taiwan Semiconductor is a 15A, 600V AEC-Q101-qualified low forward-voltage quad bridge rectifier in GBU package, featuring 0.90V max VF at 7.5A/25°C and 200A IFSM (8.3ms), used in automotive-grade SMPS and lighting power supplies.
For engineers reviewing the GBU15L05H datasheet, GBU15L05H pinout, GBU15L05H application, or GBU15L05H equivalent, key selection criteria include its AEC-Q101 qualification, 600V VRRM rating, 0.90V max forward voltage, 150°C junction temperature limit, and GBU package thermal resistance of 3°C/W (junction-to-case).
Technical Context
This discrete bridge rectifier integrates four silicon diodes in a single-phase full-wave configuration with oxide planar chip junctions. It delivers 15A average forward current and withstands 600V repetitive peak reverse voltage, supporting high-efficiency operation in compact power converters.
Thermal performance is defined by RθJC = 3°C/W and RθJA = 15°C/W, enabling reliable operation up to 150°C junction temperature. Its AEC-Q101 qualification confirms suitability for automotive under-hood applications requiring robust surge immunity and long-term reliability.

Equivalent & Alternatives
The following parts are listed as comparable options for similar bridge rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| GBU15K | 600V VRRM, non-AEC-Q101, 1.1V max VF @ 7.5A | General-purpose industrial/commercial power supplies without automotive qualification | Lower cost where AEC-Q101 and low VF are not required |
| GBU15J | 600V VRRM, non-AEC-Q101, 1.05V max VF @ 7.5A, same GBU package | Cost-sensitive consumer adapters and lighting drivers with moderate efficiency targets | Acceptable substitute if 0.15V higher VF and absence of automotive qualification are acceptable |
Compared with GBU15K and GBU15J, the GBU15L05H provides superior efficiency (0.90V vs. ≥1.05V VF), guaranteed automotive reliability (AEC-Q101), and tighter thermal resistance-making it optimal for thermally constrained, mission-critical, or regulated environments where long-term conduction loss and qualification matter.

FAQ
What is the peak repetitive reverse voltage rating of the GBU15L05H?
The GBU15L05H has a peak repetitive reverse voltage (VRRM) rating of 600 V. This value is confirmed in the Absolute Maximum Ratings table of the official Taiwan Semiconductor datasheet (Version C2103). It defines the maximum AC voltage the device can block during normal operation without entering avalanche breakdown. Exceeding this rating risks irreversible damage.
Is the GBU15L05H pin-compatible with standard GBU-package bridge rectifiers?
Yes, the GBU15L05H uses the industry-standard GBU package with identical mechanical dimensions and 4-pin terminal layout (AC1, AC2, +, –). Its pinout matches other GBU-series rectifiers such as GBU15K and GBU15J, enabling drop-in replacement in existing PCB footprints when thermal and electrical margins permit.
Does the GBU15L05H require a heatsink in typical 15A operation?
The GBU15L05H has RθJC = 3°C/W and RθJA = 15°C/W. At 15A with 0.90V VF, power dissipation is ~13.5W. Without forced airflow or copper pour, junction temperature will exceed 150°C. A heatsink or ≥2 oz copper plane is required for continuous 15A operation per the derating curve in the datasheet.
What does the "H" suffix in GBU15L05H signify?
The "H" suffix in GBU15L05H indicates AEC-Q101 qualification. Per Taiwan Semiconductor's Ordering Information table, "H" denotes full automotive-grade reliability testing-including temperature cycling, high-temperature reverse bias, and mechanical shock-verified per AEC-Q101 Rev D. This distinguishes it from non-H variants like GBU15L05.
How does the forward voltage of GBU15L05H compare to GBU15L06H at 7.5A and 25°C?
At 7.5A and 25°C, the GBU15L05H has a maximum forward voltage (VF) of 0.90 V, while the GBU15L06H is rated at 0.96 V max under identical conditions. Both share the same low-VF design, but the GBU15L05H offers marginally lower conduction loss due to its optimized 600V-rated die structure.
