Product details
Overview
TD430N22KOFHPSA2 from Infineon Technologies is a press-pack, double-sided cooled phase-control thyristor module rated for 2200 V repetitive peak off-state voltage and 430 A average on-state current at 85 °C case temperature. It features electrically insulated baseplate, pre-applied thermal interface material (TIM), and Advanced Medium Power Technology (AMPT) for industrial power control in soft starters and static switches.
For engineers reviewing the TD430N22KOFHPSA2 datasheet, TD430N22KOFHPSA2 pinout, TD430N22KOFHPSA2 application, or TD430N22KOFHPSA2 equivalent, key selection criteria include junction-to-case thermal resistance (0.062 K/W), critical dv/dt rating (1000 V/µs), gate trigger current (≤250 mA), and surge current capability (14 kA, 10 ms).
Technical Context
This thyristor module implements a dual-arm, symmetrical press-contact structure with silicon pellets mounted on aluminum nitride (AlN) insulation. It supports line-commutated operation with 300 µs typical turn-off time under 100 V reverse voltage and 20 V/µs dv/dt conditions.
Designed for high-reliability medium-power AC phase control, it delivers 1.78 V maximum on-state voltage at 1500 A and 125 °C junction temperature, with 0.45 mΩ slope resistance and 150 A/µs critical di/dt rating to ensure robust triggering and commutation stability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDRM / VRRM | 2200 V - Maximum repetitive forward/reverse blocking voltage; defines AC line voltage compatibility up to 1.5 kV RMS systems. |
| ITAVM (TC = 85 °C) | 430 A - Continuous average on-state current per arm; sets steady-state conduction capacity in rectifier or controller topologies. |
| ITSM (10 ms) | 14000 A - Non-repetitive surge current; determines short-circuit withstand capability during fault events. |
| RthJC | 0.062 K/W - Junction-to-case thermal resistance per module; enables thermal design of heatsink interface for ≤125 °C max junction temperature. |
| (dv/dt)cr | 1000 V/µs - Critical rate of rise of off-state voltage; ensures reliable blocking without spurious turn-on under fast transients. |
| VT0 / rT | 0.95 V / 0.45 mΩ - Threshold voltage and slope resistance; defines conduction loss profile and forward voltage drop linearity. |
| tq (typ.) | 300 µs - Circuit commutated turn-off time; constrains minimum commutation interval in phase-controlled bridge configurations. |
Pinout & Package
TD430N22KOFHPSA2 is housed in an industrial-standard press-pack module with electrically insulated AlN baseplate and 60 mm × 60 mm footprint. Mechanical terminals conform to M2 (12 Nm) torque specification for power connections and DIN 46244 A (2.8 × 0.8 mm) for gate control leads.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (A1) | Main power terminal (arm 1) | High-current input path for one thyristor arm; requires low-inductance busbar connection. |

| Anode (A2) | Main power terminal (arm 2) | Second arm anode; enables full-bridge or back-to-back configuration with independent gate control. |
| Cathode (K2) | Main power terminal (arm 2) | Second arm cathode; isolated from K1 by internal AlN insulation for true dual-arm operation. |
| Gate (G1) | Control input (arm 1) | Low-energy trigger interface requiring ≤2.2 V gate voltage and ≥1 A pulse for reliable latching. |
| Gate (G2) | Control input (arm 2) | Independent gate drive node; supports asynchronous or complementary firing sequences. |
Key Features
| Feature | Design Value |
|---|---|
| Pressure contact technology | Eliminates wire bonds and solder layers, enabling >10⁶ thermal cycles and stable RthJC over lifetime. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar phase-control thyristor module applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TT430N22KOFHPSA2 | Same die, identical electrical specs, but uses non-pre-applied TIM and standard baseplate insulation (3.0 kV test voltage). | Lacks pre-applied TIM; requires manual TIM application and additional isolation verification for grounded heatsinks. | Select when thermal interface process control is available and cost sensitivity outweighs assembly simplification. |
| TD430N22KO1FHPSA2 | Includes enhanced dv/dt rating (1200 V/µs) and tighter VT0 tolerance (0.90 V max), but same ITAVM and RthJC. | Better suited for high-dv/dt environments (e.g., long cable feeds, transformer-coupled sources) without derating. | Choose where system-level transients exceed 1000 V/µs and gate drive timing margins are constrained. |
Compared with TT430N22KOFHPSA2 and TD430N22KO1FHPSA2, TD430N22KOFHPSA2 uniquely balances pre-applied TIM convenience, 3.6 kV isolation, and proven 1000 V/µs dv/dt immunity-making it optimal for volume industrial drives and UPS where assembly yield and thermal predictability are prioritized.

FAQ
What is the maximum allowable junction temperature for TD430N22KOFHPSA2?
The maximum junction temperature (Tvj max) is 125 °C, validated per IEC 60747-6. Operation beyond this limit risks irreversible degradation of the silicon die and pressure-contact interface. Thermal design must ensure that under worst-case ITAVM and ambient conditions, junction temperature remains ≤125 °C using the provided ZthJC transient impedance model.
Does TD430N22KOFHPSA2 require forced air or liquid cooling?
No mandatory forced cooling is required, but thermal management must be designed per application duty cycle. With RthCH = 0.0075 K/W (with TIM) and RthJC = 0.062 K/W, natural convection may suffice only below ~150 A ITAVM. At full 430 A rating, a heatsink with RthCA ≤ 0.12 K/W and active airflow or liquid coupling is recommended to maintain TC ≤ 85 °C.
Can TD430N22KOFHPSA2 be used in anti-parallel configuration for AC switching?
Yes - its dual-arm, electrically isolated structure supports true anti-parallel connection without external isolation. Each arm (A1/K1 and A2/K2) operates independently with separate gate inputs, enabling bidirectional AC conduction control in static switch or solid-state relay implementations.
Is the pre-applied TIM reworkable or replaceable?
The pre-applied TIM is factory-cured and not intended for removal or rework. Attempting to scrape or clean it compromises bond integrity and voids warranty. If replacement is necessary due to contamination or damage, Infineon specifies use of Dow Corning TC-5632 or Henkel Loctite ABLESTIK QMI510 as qualified alternatives applied at 0.1–0.15 mm thickness.
