Product details
Overview
TUAU10GH from Taiwan Semiconductor is a 10A, 400V repetitive peak reverse voltage (VRRM) surface-mount ultrafast rectifier in TO-277A (SMPC4.6U) package, featuring 1.06V max forward voltage at 10A/25°C, 50ns max reverse recovery time, and AEC-Q101 qualification for automotive-grade reliability in DC-DC converters and freewheeling circuits.
For engineers reviewing the TUAU10GH datasheet, TUAU10GH pinout, TUAU10GH application, or TUAU10GH equivalent, key selection criteria include its 400V VRRM, wettable flank leads for automated optical inspection, 150A surge rating, -55°C to +150°C operating junction temperature range, and compliance with JESD201 Class 2 whisker resistance and RoHS/halogen-free standards.
Technical Context
The TUAU10GH is a single-die, glass-passivated silicon planar junction rectifier optimized for high-efficiency switching power supplies. Its ultrafast recovery (≤50ns) minimizes switching losses in high-frequency topologies, while the TO-277A package's low RθJL of 5.0°C/W supports thermal management on standard PCB copper pads.
Designed for automotive and industrial environments, it delivers stable reverse leakage (<5µA at 25°C, <12µA at 125°C) across its rated voltage range and maintains forward voltage performance over temperature - 0.88V typ. at 10A/125°C - enabling predictable conduction loss modeling in thermal design.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 400 V - maximum repetitive reverse blocking voltage without breakdown |
| IF | 10 A - continuous average forward current at case temperature ≤75°C |
| IFSM | 150 A - non-repetitive surge current capability (8.3ms half-sine) |
| trr | ≤50 ns - ultrafast reverse recovery time reduces switching losses in SMPS |
| VF | 1.06 V max at 10A/25°C - low conduction loss enables higher efficiency in high-current paths |
| RθJL | 5.0 °C/W - junction-to-lead thermal resistance supports direct heat transfer to PCB copper |
| Junction Temp | -55°C to +150°C - extended operating range suitable for under-hood automotive use |

Equivalent & Alternatives
The following parts are listed as comparable options for similar ultrafast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH10R04DJF | 400V VRRM, 10A IF, 45ns trr, TO-277A package, but not AEC-Q101 qualified | Lacks automotive qualification; suitable for industrial/commercial DC-DC only | Select when AEC-Q101 is not required and slightly faster recovery is prioritized |
| ON Semi MUR1040 | 400V VRRM, 10A IF, 60ns trr, DO-214AB package, no wettable flanks | Different footprint requires PCB redesign; lacks MSL Level 1 and AEC-Q101 | Choose only if TO-277A is unavailable and lead-free reflow compatibility is confirmed |
Compared with STTH10R04DJF and MUR1040, the TUAU10GH uniquely combines AEC-Q101 qualification, wettable flank leads, and J-STD-020 Level 1 moisture sensitivity - making it the only drop-in option for automotive production lines requiring full process traceability and AOI support without layout change.

FAQ
What is the maximum junction temperature rating for the TUAU10GH?
The TUAU10GH has a maximum junction temperature (TJ) rating of +150°C, validated per its AEC-Q101 qualification. This allows operation in under-hood automotive environments where ambient temperatures exceed 105°C, provided thermal design maintains junction temperature within this limit using the specified RθJL = 5.0°C/W path to PCB copper.
Does the TUAU10GH support lead-free reflow soldering?
Yes, the TUAU10GH features matte tin-plated leads compliant with J-STD-002 solderability requirements and rated for lead-free reflow profiles up to 260°C peak. Its J-STD-020 moisture sensitivity level is Level 1, meaning no baking is required prior to assembly - simplifying manufacturing flow and reducing risk of popcorning.
How does the TUAU10GH's reverse recovery time compare to standard fast rectifiers?
The TUAU10GH specifies ≤50ns reverse recovery time (trr), placing it in the ultrafast rectifier category. This is approximately 2–3× faster than standard fast recovery rectifiers (typically 100–200ns), directly reducing switching losses and EMI generation in high-frequency DC-DC converters operating above 100kHz.
Is the TUAU10GH pin-compatible with other parts in the TUAU10xH series?
Yes, all TUAU10xH variants - including TUAU10DH, TUAU10GH, TUAU10JH, TUAU10KH, and TUAU10MH - share identical TO-277A (SMPC4.6U) packaging, pinout, and mechanical dimensions. Only the VRRM rating differs (200V to 1000V), enabling direct substitution based on system voltage requirements without PCB changes.
What is the significance of the "wettable flank" feature on the TUAU10GH?
The wettable flank design on the TUAU10GH provides solderable sidewalls on its leads, enabling automated optical inspection (AOI) of solder fillet formation during SMT reflow. This improves process yield and field reliability in high-volume automotive production, where void detection and solder joint integrity are critical quality checkpoints.
