Product details
Overview
TUAU10JH from Taiwan Semiconductor is a 10A, 600V high-efficiency surface-mount ultrafast rectifier in TO-277A (SMPC4.6U) package, featuring 1.34V forward voltage at 10A/25°C, 50ns reverse recovery time, and AEC-Q101 qualification for automotive-grade reliability in freewheeling and snubber circuits.
For engineers reviewing the TUAU10JH datasheet, TUAU10JH pinout, TUAU10JH application, or TUAU10JH equivalent, key selection criteria include its 600V VRRM, wettable flank terminals for automated optical inspection, 175°C max junction temperature, and thermal resistance of 5.0°C/W (junction-to-lead).
Technical Context
The TUAU10JH is a single-die, silicon planar ultrafast recovery rectifier with glass-passivated junction and optimized carrier lifetime control to achieve 50ns trr while maintaining low leakage (<5µA @ 25°C, <12µA @ 125°C). Its TO-277A package integrates wettable flank leads compliant with J-STD-020 Level 1 moisture sensitivity.
Designed for high-frequency switching environments, it delivers stable forward conduction across -55°C to +175°C operating range, with RθJL = 5.0°C/W enabling efficient heat transfer to PCB copper pads under 10A DC load conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 600 V - Maximum repetitive reverse voltage; defines safe blocking capability in 400–600V DC bus applications |
| IF | 10 A - Continuous average forward current; supports sustained power delivery in compact SMT layouts |
| trr | 50 ns - Ultrafast reverse recovery; minimizes switching losses in 100–500 kHz DC/DC converters |
| VF @ 10A, 25°C | 1.34 V - Forward voltage drop; determines conduction loss and thermal rise at rated current |
| IR @ 600V, 25°C | <5 µA - Low reverse leakage; preserves efficiency in high-impedance snubber and hold-up circuits |
| RθJL | 5.0 °C/W - Junction-to-lead thermal resistance; enables direct thermal path to PCB without heatsink in 10A designs |
| Junction Temp Range | -55°C to +175°C - Extended operating range suitable for under-hood automotive environments |
Pinout & Package
TO-277A (SMPC4.6U) surface-mount package with cathode-indicating band, matte tin-plated wettable flank leads, and 0.114g mass. Designed for reflow soldering per J-STD-002 and whisker-resistant per JESD201 Class 2.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry | Connected to lower-potential side (e.g., switch node in buck converter); requires thermal pad connection for heat dissipation |
| Cathode | Forward current exit / reverse blocking terminal | Marked by band; ties to higher-potential rail (e.g., output capacitor positive); critical for polarity-sensitive freewheeling paths |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar ultrafast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH10R06DJF | 600V, 10A, 55ns trr, TO-277A, but no AEC-Q101 qualification | Lacks automotive stress validation; limited to industrial/commercial use | Select when AEC-Q101 is not required and slightly higher trr is acceptable |
| ON Semi MUR1060CT | 600V, dual common-cathode configuration in TO-220AC; 60ns trr; no wettable flanks | Through-hole mounting only; unsuitable for AOI-enabled SMT lines | Choose only if legacy through-hole assembly is mandated and dual-diode topology is needed |
Compared with STTH10R06DJF and MUR1060CT, the TUAU10JH uniquely combines AEC-Q101 qualification, wettable flank leads for automated inspection, and 50ns recovery in a single-die TO-277A package-making it optimal for next-gen automotive SMT power modules where reliability, manufacturability, and high-frequency efficiency are jointly prioritized.

FAQ
What is the maximum repetitive peak reverse voltage (VRRM) of the TUAU10JH?
The TUAU10JH has a VRRM of 600 V, verified per datasheet Section "Absolute Maximum Ratings." This rating ensures reliable blocking of transient voltages up to 600V in DC bus and snubber applications. The TUAU10JH must not be operated beyond this limit to prevent avalanche breakdown or permanent junction damage.
Is the TUAU10JH qualified for automotive applications?
Yes, the TUAU10JH is AEC-Q101 qualified, confirmed in the "Features" section of the official datasheet. This qualification covers stress tests including high-temperature reverse bias (HTRB), temperature cycling (TC), and highly accelerated temperature-humidity bias (HAST), making the TUAU10JH suitable for under-hood and body electronics in passenger vehicles and commercial fleets.
What is the forward voltage (VF) of the TUAU10JH at 10A and 25°C?
The TUAU10JH exhibits a typical forward voltage of 1.34 V at 10A and 25°C, with a maximum of 1.7 V under the same conditions, as specified in the "Electrical Specifications" table. This value directly impacts conduction loss and thermal design-engineers should use 1.34 V for nominal loss calculation and 1.7 V for worst-case thermal margining.
Does the TUAU10JH have wettable flank leads?
Yes, the TUAU10JH features wettable flank leads per the "Features" list and mechanical data section. These leads enable full-side solder fillet inspection using automated optical inspection (AOI) systems, improving process yield and field reliability in high-volume SMT manufacturing lines-especially critical for automotive Tier 1 suppliers.
What is the reverse recovery time (trr) of the TUAU10JH?
The TUAU10JH has a maximum reverse recovery time of 50 ns, measured at IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A, as stated in the "Electrical Specifications" table. This ultrafast recovery minimizes switching losses and EMI in high-frequency DC/DC topologies such as QR flyback and phase-shifted full-bridge converters.
