Product details
Overview
TPUH6J from Taiwan Semiconductor is a 600 V, 6 A ultrafast recovery rectifier diode in TO-277 surface-mount package, with 50 ns reverse recovery time (trr), 1.85 V forward voltage (VF) at 6 A, and 100 µA maximum reverse leakage current (IR) at 600 V, used in high-frequency AC/DC converters and PFC stages.
For engineers reviewing the TPUH6J datasheet, TPUH6J pinout, TPUH6J application, or TPUH6J equivalent, key selection criteria include its ultrafast switching performance, thermal resistance (RθJA = 50 °C/W), junction temperature rating (TJ = 175 °C), and compatibility with automated SMT assembly on standard PCB pad layouts per JEDEC TO-277.
Technical Context
The TPUH6J employs an optimized epitaxial planar structure to achieve fast soft-recovery characteristics critical for reducing EMI and switching losses in continuous-conduction-mode (CCM) PFC circuits. Its 50 ns trr is measured under standardized conditions (IF = 6 A, di/dt = 100 A/µs, TJ = 25 °C).
Thermal design is enabled by low RθJC (1.5 °C/W) and a molded plastic body compliant with JEDEC TO-277 Issue A. The device supports repetitive peak reverse voltage (VRRM) of 600 V and surge current (IFSM) up to 100 A (8.3 ms single half-sine wave).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 600 V - Maximum repetitive peak reverse voltage; defines safe blocking capability in bridge or boost diode positions. |
| IF(AV) | 6 A - Average forward current at TC = 115 °C; sets continuous power-handling limit in thermally managed layouts. |
| trr | 50 ns - Reverse recovery time at IF = 6 A, di/dt = 100 A/µs; enables operation up to ~200 kHz without excessive switching loss. |
| VF | 1.85 V @ 6 A - Forward voltage drop; directly impacts conduction loss and thermal rise in high-current paths. |
| IR | 100 µA @ 600 V, TJ = 25 °C - Low leakage ensures minimal standby power loss and stable voltage hold-off. |
| TJ max | 175 °C - Maximum junction temperature; allows reliable operation in compact, high-power-density industrial power supplies. |
Pinout & Package
TPUH6J is housed in a single-diode TO-277 (SMP) surface-mount package with cathode-indicated molded plastic body (JEDEC TO-277 Issue A). Dimensions: 6.50 × 4.30 × 1.40 mm (L × W × H), with 3-pin terminal configuration (Anode, Cathode, Cathode tab).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (Anode) | Anode connection | Primary current entry point; requires low-inductance trace routing in high-di/dt applications. |
| Pin 2 (Cathode) | Cathode connection | Current exit path; electrically tied to exposed cathode tab for thermal and electrical return. |
| Tab (Cathode) | Thermal & electrical cathode | Exposed metal pad for soldering to PCB copper pour; provides primary thermal path (RθJC = 1.5 °C/W). |
Key Features
| Feature | Design Value |
|---|---|
| Ultrafast recovery | 50 ns trr minimizes switching loss and EMI generation in high-frequency PFC and SMPS outputs. |
| High surge rating | 100 A IFSM (8.3 ms) supports robust inrush and transient overload handling in AC input stages. |
| Low thermal resistance | RθJC = 1.5 °C/W enables efficient heat transfer to PCB, reducing need for external heatsinks. |
| JEDEC-compliant SMT package | TO-277 outline ensures compatibility with standard pick-and-place equipment and reflow profiles. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar ultrafast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH6L06D | Same VRRM (600 V), slightly higher VF (1.9 V @ 6 A), trr = 55 ns, TO-277 package. | Marginally higher conduction loss; suitable where 5 ns trr difference is acceptable. | Prefer TPUH6J when minimizing EMI in noise-sensitive PFC designs. |
| VS-6EWH06FN-M3 | Identical VRRM, IF(AV), and trr; lower VF (1.75 V @ 6 A); same TO-277 footprint. | Better conduction efficiency; tighter VF distribution across temperature. | Select VS-6EWH06FN-M3 for highest efficiency in thermally constrained 12 V output rails. |
Compared with STTH6L06D and VS-6EWH06FN-M3, the TPUH6J offers balanced trade-offs between ultrafast recovery, forward voltage, and thermal robustness-making it optimal for cost-sensitive industrial PFC and AC/DC front-end designs requiring proven JEDEC TO-277 reliability.

FAQ
What is the maximum junction temperature rating for TPUH6J?
The TPUH6J has a maximum junction temperature (TJ) rating of 175 °C. This allows sustained operation in high-ambient environments such as enclosed industrial power supplies or UPS systems. Derating curves in the official TPUH6J datasheet specify allowable current reduction above TC = 115 °C, ensuring safe thermal margin under full load.
Does TPUH6J support automated SMT assembly?
Yes, TPUH6J uses a JEDEC TO-277 (SMP) surface-mount package with defined pad layout and thermal pad dimensions. It is compatible with standard reflow profiles (peak ≤ 260 °C) and pick-and-place equipment. The cathode tab must be soldered to a minimum 100 mm² copper pour for optimal thermal performance in the TPUH6J layout.
What is the reverse recovery time (trr) of TPUH6J and under what test conditions?
The TPUH6J has a reverse recovery time (trr) of 50 ns, measured at IF = 6 A, di/dt = 100 A/µs, and TJ = 25 °C. This value is confirmed in the TPUH6J datasheet revision E2309 and reflects soft-recovery behavior critical for minimizing switching noise in PFC and SMPS applications.
How does TPUH6J compare to standard fast recovery diodes in terms of EMI generation?
Due to its 50 ns trr and soft recovery profile, the TPUH6J generates significantly less high-frequency ringing and conducted EMI than standard fast recovery diodes (trr > 100 ns). In actual 65 kHz PFC designs, this reduces common-mode filter size by ~30% and eases EMC compliance testing for the TPUH6J-based system.
Is TPUH6J pin-compatible with other TO-277 ultrafast diodes like STTH6L06D?
Yes, TPUH6J shares identical TO-277 mechanical dimensions, terminal locations, and cathode marking with STTH6L06D and VS-6EWH06FN-M3. All three use the same 3-terminal (anode/cathode/tab) configuration and JEDEC-compliant footprint, enabling direct board-level substitution without layout changes-provided thermal and electrical margins remain verified for the TPUH6J application.
