Taiwan Semiconductor Corporation GBU15L06H

Overview

GBU15L06H from Taiwan Semiconductor is a 15A, 800V AEC-Q101-qualified low-V_F standard bridge rectifier in GBU package, featuring 0.93V typical forward voltage at 7.5A/25°C, 200A surge rating (8.3ms), and 150°C max junction temperature. It serves as the primary AC-to-DC conversion stage in automotive-grade power supplies.

For engineers reviewing the GBU15L06H datasheet, GBU15L06H pinout, GBU15L06H application, or GBU15L06H equivalent, key selection criteria include peak reverse voltage (800V), thermal resistance (R_θJC = 3°C/W), AEC-Q101 qualification status, low forward drop for efficiency-critical designs, and GBU package compatibility with high-power board layouts.

Technical Context

This quad-configuration bridge rectifier integrates four silicon diodes in a single GBU molded package with oxide planar chip junctions. Its design supports high-reliability operation under repetitive 800V reverse stress and transient 200A surge currents, with thermal performance optimized via low R_θJC (3°C/W) for conduction-limited thermal management.

The device delivers stable reverse leakage ≤5µA at 25°C and ≤150µA at 125°C, while maintaining forward voltage consistency across temperature - 0.93V typ. at 25°C and unmeasured but bounded per spec at 125°C. UL Recognized (E-326243) and halogen-free construction meet automotive and industrial safety requirements.

FAQ

What is the peak repetitive reverse voltage rating for GBU15L06H?

The GBU15L06H has a peak repetitive reverse voltage (V_RRM) rating of 800 V, verified per Taiwan Semiconductor's official datasheet revision C2103. This rating allows safe operation with 560 V_RMS input voltage and provides margin against line surges. The "06" in the part number explicitly denotes the 800V grade, distinguishing it from the 600V GBU15L05 variant.

Is GBU15L06H qualified to AEC-Q101, and what does the "H" suffix indicate?

Yes, GBU15L06H is AEC-Q101 qualified - the "H" suffix in the ordering code explicitly denotes this qualification per Taiwan Semiconductor's ordering information table. This means the GBU15L06H has undergone stress testing for automotive temperature cycling, humidity, and mechanical shock, making it suitable for under-hood and cabin power electronics where reliability is mission-critical.

What is the typical forward voltage of GBU15L06H at 7.5A and 25°C?

The typical forward voltage (V_F) of GBU15L06H is 0.93 V at 7.5 A and 25°C, with a maximum of 0.96 V under the same conditions. This value is measured per diode within the bridge and reflects the low-V_F design that improves system efficiency. At 125°C, V_F decreases but is not specified in the datasheet beyond typ. behavior.

Does GBU15L06H have UL recognition, and what is the file number?

Yes, GBU15L06H is UL Recognized with File # E-326243, as confirmed in the Mechanical Data section of the official datasheet. This recognition applies to the GBU package construction and validates compliance with UL 94V-0 flammability and electrical safety requirements for end-product certification in North America and other UL-accepting regions.

What is the junction-to-case thermal resistance (R_θJC) of GBU15L06H, and why does it matter?

The junction-to-case thermal resistance (R_θJC) of GBU15L06H is 3°C/W, a key thermal parameter published in the Thermal Performance table. This low value enables efficient heat transfer from the silicon die to the external heatsink or PCB copper, allowing higher sustained current operation without exceeding the 150°C maximum junction temperature - especially critical in compact, sealed, or high-ambient-temperature applications.
