Product details
Overview
TUAU6JH from Taiwan Semiconductor is a 6A, 600V glass-passivated surface-mount rectifier in TO-277A (SMPC4.6U) package, featuring 1.17V max forward voltage at 6A/25°C, 50ns reverse recovery time, and AEC-Q101 qualification for automotive-grade reliability. It serves as a high-efficiency freewheeling or output rectifier in DC-DC converters and industrial SMPS.
For engineers reviewing the TUAU6JH datasheet, TUAU6JH pinout, TUAU6JH application, or TUAU6JH equivalent, key selection criteria include its 600V VRRM rating, wettable flank terminals for automated optical inspection, junction-to-lead thermal resistance of 6°C/W, and 150°C maximum junction temperature for high-temperature operation.
Technical Context
The TUAU6JH is a single-die, fast-recovery silicon rectifier optimized for switching power supplies operating up to 100 kHz. Its design integrates glass passivation for stable leakage performance and low stored charge (Qrr implied by trr ≤ 50 ns), enabling reduced switching losses in hard-switched topologies.
Thermal performance is defined for mounting on a 16 mm × 16 mm copper pad: RθJL = 6°C/W enables efficient heat transfer to PCB copper, while RθJA = 50°C/W reflects ambient-limited dissipation in standard layouts. The device's 150°C TJ max rating aligns with AEC-Q101 stress conditions for under-hood automotive use.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 600 V - Maximum repetitive reverse blocking voltage; defines safe operating range in 48–400 V bus applications. |
| IF | 6 A - Continuous forward current rating at TC = 110°C; supports compact heatsink-free designs up to ~15 W output. |
| VF (6A, 25°C) | 1.17 V max - Low conduction loss ensures >92% efficiency in 12 V output SMPS at full load. |
| trr | 50 ns max - Fast recovery minimizes switching loss and EMI in high-frequency converters (≥50 kHz). |
| RθJL | 6 °C/W - Enables direct thermal coupling to PCB copper; allows 10 W dissipation with <60°C temperature rise above lead. |
| IR (125°C) | 100 µA max - Low leakage preserves efficiency in high-temperature environments like motor drives or inverters. |
| CJ | 64 pF - Junction capacitance impacts snubber design and EMI filtering requirements in flyback and LLC topologies. |
Pinout & Package
Package: TO-277A (SMPC4.6U) - Surface-mount, single-anode/single-cathode configuration with wettable flank leads and cathode band polarity marking.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

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-M3/45 | Same 600 V VRRM, 6 A IF, but TO-277A package with 1.25 V VF (6A/25°C) and 60 ns trr. | Higher VF increases conduction loss; slightly slower recovery may require larger snubbers in >150 kHz designs. | Acceptable where thermal margin exists and cost sensitivity outweighs efficiency optimization. |
| ON Semiconductor MUR660CT | 600 V, 6 A dual common-cathode configuration in TO-220AC; VF = 1.7 V (6A/25°C), trr = 60 ns. | Through-hole package requires manual or wave soldering; higher VF degrades efficiency in space-constrained SMPS. | Only suitable when TO-220 mechanical fit is required or dual-diode topology is needed. |
Compared with VS-6EWH06FN-M3/45 and MUR660CT, the TUAU6JH delivers lower forward voltage and faster recovery in a surface-mount AEC-Q101-qualified package-making it optimal for high-density, high-efficiency automotive and industrial power converters where thermal performance and manufacturability are critical.

FAQ
What is the maximum junction temperature for the TUAU6JH?
The TUAU6JH has a maximum junction temperature (TJ max) of +150°C, validated under AEC-Q101 stress testing conditions. This rating applies when mounted on a 16 mm × 16 mm copper pad per JEDEC standards. Operation beyond this temperature risks parametric shift and accelerated failure; derating curves in the datasheet define safe IF versus TC limits.
Does the TUAU6JH have wettable flank leads?
Yes, the TUAU6JH features wettable flank leads in its TO-277A (SMPC4.6U) package. These chamfered, fully plated side surfaces enable automated optical inspection (AOI) of solder fillet formation during reflow, supporting IPC-A-610 Class 2 and Class 3 assembly verification without requiring X-ray inspection.
What is the reverse recovery time (trr) specification for the TUAU6JH?
The TUAU6JH has a maximum reverse recovery time (trr) of 50 ns, measured at IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A. This fast recovery characteristic reduces switching losses and voltage overshoot in high-frequency DC-DC converters and motor drive inverters operating up to 200 kHz.
Is the TUAU6JH compliant with halogen-free and RoHS requirements?
Yes, the TUAU6JH is halogen-free per IEC 61249-2-21 and RoHS compliant per EU Directive 2011/65/EU. The molding compound and matte tin-plated leads meet both environmental standards, making it suitable for green manufacturing and global export without restriction.
How does the TUAU6JH differ from the TUAU6DH and TUAU6MH variants?
The TUAU6JH is the 600 V variant in the TUAU6xH family; TUAU6DH is 200 V (VF = 0.89 V max), and TUAU6MH is 1000 V (VF = 1.48 V max). All share identical package (TO-277A), current rating (6 A), thermal specs (RθJL = 6°C/W), and AEC-Q101 qualification-but differ in VRRM, VF, trr, and CJ to match system voltage and efficiency targets.
