Product details
Overview
TUAU6JH from Taiwan Semiconductor is a 6A, 600V glass-passivated surface-mount rectifier in TO-277A (SMPC4.6U) package, featuring low forward voltage (1.17 V at 6A, 25°C), fast reverse recovery time (≤50 ns), and AEC-Q101 qualification for automotive-grade reliability. It serves as a high-efficiency freewheeling or output rectifier in DC/DC converters and SMPS.
For engineers reviewing the TUAU6JH datasheet, TUAU6JH pinout, TUAU6JH application, or TUAU6JH equivalent, key selection factors include its 600V VRRM, 140A IFSM, wettable flank leads for solder inspection, J-STD-020 Level 1 moisture sensitivity, and thermal resistance RθJL = 6°C/W - critical for thermally constrained power designs.
Technical Context
The TUAU6JH is a single-die, silicon planar junction rectifier with glass passivation for enhanced ruggedness and stability under thermal cycling. Its design targets high-frequency switching applications where low conduction loss and fast recovery minimize switching losses.
It operates across a junction temperature range of –55°C to +150°C (not +175°C), with thermal performance characterized on a 16 mm × 16 mm PCB copper pad. Junction-to-lead thermal resistance (6°C/W) enables efficient heat transfer to the PCB, supporting compact layout in space-constrained power stages.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 600 V - maximum repetitive reverse voltage; defines safe blocking capability in 600V-class power rails |
| IF | 6 A - continuous forward current rating at TA = 25°C; derates to zero at 150°C junction |
| VF | 1.17 V (max @ 6A, 25°C) - low conduction loss enabling >92% efficiency in 12V–48V output rectification |
| trr | ≤50 ns - fast recovery minimizes reverse recovery charge (Qrr) and associated switching loss in 100–500 kHz converters |
| CJ | 64 pF (@1 MHz, 4V) - low junction capacitance reduces capacitive turn-on loss and EMI generation |
| RθJL | 6 °C/W - enables direct thermal coupling to PCB copper, simplifying thermal design without heatsinks below ~4W dissipation |
Pinout & Package
Package: TO-277A (SMPC4.6U), surface-mount, single-anode/single-cathode configuration with cathode band marking. Wettable flank leads support automated optical solder-joint inspection.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry point during forward conduction | Connected to lower-potential side (e.g., switch node or ground return); requires low-inductance routing |
| Cathode | Current exit point during forward conduction | Connected to higher-potential rail (e.g., output capacitor positive); marked by visible band on package |
| Lead (exposed metal tab) | Thermal path and mechanical anchor | Electrically connected to cathode; must be routed to large copper pour for thermal management |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive underhood applications including engine control modules and ADAS power supplies |
| Glass-passivated junction | Prevents moisture ingress and metallization corrosion, ensuring long-term reliability in humid environments |
| Wettable flank leads | Enables automated X-ray or AOI inspection of solder fillets without requiring cross-sectioning |
| J-STD-020 Level 1 MSL | No bake preconditioning required before reflow; supports standard SMT assembly without moisture-related popcorning |
| Halogen-free & RoHS compliant | Meets IEC 61249-2-21 and EU RoHS Directive 2011/65/EU for environmentally regulated end equipment |
Applications
| Switch Mode Power Supply | Inverter DC Link |
|---|---|
Use Scenario: Secondary-side synchronous rectification in 36–60V telecom and server PSUs operating at 200–300 kHz. IC Role / Device Role / Timing Role: Output rectifier replacing Schottky diodes to reduce conduction loss while maintaining fast recovery. Use Value: 1.17 V VF at 6A lowers average power loss by ~0.4 W vs. 1.5 V alternatives, improving thermal margin in sealed enclosures. | Use Scenario: Freewheeling path in 3-phase motor inverters for HVAC compressors and industrial pumps. IC Role / Device Role / Timing Role: Clamp diode across IGBTs to absorb inductive kickback energy during turn-off. Use Value: 140 A IFSM withstands high-current transients; 50 ns trr limits voltage overshoot and snubber losses. |
| DC/DC Converter | Automotive Body Control Module |
Use Scenario: Isolated flyback or forward converter in 12V/24V automotive auxiliary supplies. IC Role / Device Role / Timing Role: Primary-side clamp or secondary-side rectifier handling 6A continuous load. Use Value: AEC-Q101 qualification and –55°C to +150°C operation ensure compliance with automotive ambient and junction temp requirements. | Use Scenario: Reverse polarity protection and load dump clamping in BCM power inputs. IC Role / Device Role / Timing Role: Input protection rectifier placed between battery feed and LDO/regulator input. Use Value: 600V VRRM safely blocks ISO 7637-2 pulse 5a (load dump up to 60V + 100V transient), eliminating need for external TVS. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar high-voltage rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay VS-6EWH06FN-M3 | Same TO-277A package, 600V VRRM, but higher VF (1.35 V max @ 6A) and slower trr (75 ns) | Higher conduction loss reduces efficiency in high-duty-cycle converters; less suitable for >250 kHz operation | Select when cost priority outweighs efficiency or when legacy design validation exists |
| ON Semiconductor MUR660CT | TO-220AC package (through-hole), dual common-cathode die, 600V, but no AEC-Q101 qualification or wettable flanks | Requires manual assembly or wave soldering; unsuitable for fully automated automotive SMT lines | Select only for non-automotive industrial prototypes where footprint flexibility offsets automation constraints |
Compared with VS-6EWH06FN-M3 and MUR660CT, the TUAU6JH delivers superior thermal performance (RθJL = 6°C/W vs. ≥12°C/W), automotive qualification, and SMT process compatibility - making it optimal for volume automotive and high-reliability industrial power modules.

FAQ
What is the maximum junction temperature rating for the TUAU6JH?
The TUAU6JH has a maximum junction temperature (TJ) of +150°C, not +175°C - this is explicitly defined in the Absolute Maximum Ratings table for the TUAU6JH variant. Operation above this limit risks parametric shift and accelerated failure. Derating curves confirm zero average forward current capability at 150°C ambient on standard PCB mounting.
Does the TUAU6JH support lead-free reflow soldering per JEDEC J-STD-020?
Yes, the TUAU6JH is rated at Moisture Sensitivity Level 1 per J-STD-020, meaning it can withstand multiple reflow cycles up to 260°C peak without baking. Its matte tin-plated leads comply with IPC-J-STD-002 for solderability, and the package meets UL 94V-0 flammability requirements for lead-free assembly processes.
Is the TUAU6JH pin-compatible with other devices in the TUAU6xH family?
Yes, all TUAU6xH variants - including TUAU6DH, TUAU6GH, TUAU6JH, TUAU6KH, and TUAU6MH - share identical TO-277A (SMPC4.6U) mechanical dimensions, pinout, and thermal pad layout. Voltage rating differences do not affect physical or electrical interface compatibility, enabling drop-in replacement during design iteration or voltage binning.
What is the reverse recovery charge (Qrr) specification for the TUAU6JH?
The datasheet does not publish Qrr directly, but provides trr ≤ 50 ns under IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A test conditions. Based on typical Qrr–trr correlation for fast rectifiers, Qrr is estimated at < 25 nC - sufficient for minimizing switching loss in 200–400 kHz converters without requiring active snubbing.
Can the TUAU6JH be used in place of a Schottky diode in a 48V output rectifier?
The TUAU6JH is not a Schottky diode - it is a fast recovery silicon PN rectifier. While its 1.17 V VF is higher than typical Schottky VF, its 600V rating and AEC-Q101 qualification make it suitable where Schottky voltage limits (typically ≤200V) or temperature instability (>125°C) preclude use. For 48V outputs, it trades slightly higher conduction loss for superior reliability and surge robustness.
