Product details
Overview
TT430N22KOFXPSA1 from Infineon Technologies is a phase-control thyristor module designed for high-power AC line switching and rectification in industrial drive systems. It delivers 430 A average on-state current (ITAVM) at TC = 85 °C, 2200 V repetitive peak off-state voltage (VDRM/VRRM), and 14 kA non-repetitive surge current (ITSM), enabling robust operation in soft starters and static power controllers.
For engineers reviewing the TT430N22KOFXPSA1 datasheet, TT430N22KOFXPSA1 pinout, TT430N22KOFXPSA1 application, or TT430N22KOFXPSA1 equivalent, key selection criteria include junction-to-case thermal resistance (0.062 K/W), gate trigger current (≤250 mA), critical dv/dt rating (1000 V/µs), and pressure-contact packaging for high-cycle reliability in harsh thermal environments.
Technical Context
This dual-thyristor module implements a press-pack, electrically insulated baseplate design with Advanced Medium Power Technology (AMPT), supporting bidirectional phase-controlled conduction in B2 (two-pulse) and B6 (six-pulse) bridge configurations. Its 125 °C maximum junction temperature and 3.6 kV RMS insulation test voltage enable operation in grounded-heatsink industrial drives.
The device features a low on-state slope resistance (rT ≤ 0.45 mΩ) and threshold voltage (VT0 ≤ 0.95 V), ensuring predictable forward conduction loss at rated current. Gate control is optimized for 1 A/µs diG/dt sensitivity and ≤4 µs delay time, compatible with standard pulse transformers and opto-triggers in crowbar and bypass-switch applications.

Pinout & Package
TT430N22KOFXPSA1 uses a press-fit, double-sided insulated module package with 60 mm baseplate, conforming to industrial standard mechanical footprint. Electrical terminals are M2 screw connections (12 Nm torque) for main anode/cathode paths and DIN 46244 A 2.8 × 0.8 mm flat control terminals.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A1 (Anode 1) | Main anode of first thyristor arm | Carries full-phase current in B2/B6 bridge upper leg; requires isolated mounting to heatsink. |
| K1 (Cathode 1) | Main cathode of first thyristor arm | Connects to DC bus positive in half-wave rectifier or common cathode in full-bridge configuration. |
| A2 (Anode 2) | Main anode of second thyristor arm | Completes complementary conduction path; electrically isolated from A1/K1 per internal AlN insulation. |
| K2 (Cathode 2) | Main cathode of second thyristor arm | Routes return current in dual-arm topology; shares thermal path but not electrical path with K1. |
| G1, K1 | Gate and cathode control pair for arm 1 | Low-energy trigger interface (≤250 mA, ≤2.2 V); galvanically isolated from power terminals. |
| G2, K2 | Gate and cathode control pair for arm 2 | Independent gate drive enables asynchronous firing in phase-shifted power controllers. |
Key Features
| Feature | Design Value |
|---|---|
| Pressure contact technology | Eliminates wire bonds and solder joints, delivering >10⁶ thermal cycles without degradation in drive inverters. |
| Electrically insulated baseplate | Class 1 basic insulation (IEC 61140) with 19 mm creepage distance supports direct-mounting on grounded heatsinks. |
| Pre-applied TIM option | Reduces RthCH to 0.0075 K/W per module, cutting thermal resistance by 25% vs. standard thermal paste application. |
| High dv/dt immunity | 1000 V/µs critical rate ensures stable blocking during fast IGBT switching noise coupling in hybrid converter topologies. |
| Low VT0 + rT combination | 0.95 V threshold + 0.45 mΩ slope yields <1.78 V on-state drop at 1500 A, minimizing conduction losses in battery charger rectifiers. |

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TT500N22KOFXPSA1 | Higher ITAVM (500 A), same VDRM/RthJC, larger baseplate (70 mm) | Better suited for higher-current UPS rectifiers requiring ≥500 A DC output | Select when thermal margin is constrained and case temperature exceeds 85 °C at 430 A load. |
| TD430N22KOFXPSA1 | Single-arm configuration, identical electrical specs, no dual-gate isolation | Used in half-controlled bridges or single-phase soft starters where dual-arm symmetry is unnecessary | Choose for cost-sensitive single-phase applications or when independent gate control of two arms is not required. |
Compared with TT500N22KOFXPSA1 and TD430N22KOFXPSA1, TT430N22KOFXPSA1 offers optimal balance of dual-arm symmetry, 430 A rating, and 60 mm footprint-ideal for space-limited B6 bridge designs needing matched thermal and electrical performance across both arms.

FAQ
What is the maximum allowable case temperature for continuous operation?
The maximum case temperature (TC) is specified as +125 °C for continuous operation. However, the rated ITAVM of 430 A is defined at TC = 85 °C; derating curves in the datasheet show usable current drops to ~320 A at TC = 125 °C for sinusoidal conduction, requiring careful thermal design with RthCH ≤ 0.020 K/W.
Can TT430N22KOFXPSA1 be used in a single-phase full-wave rectifier?
Yes - it can be configured as a single-phase full-wave bridge using both arms (A1/K1 and A2/K2) with appropriate gate sequencing. The module's dual-arm architecture and isolated baseplate support this topology, though external snubbers and gate drive isolation must meet IEC 61800-5-1 requirements for single-phase line voltages up to 690 V AC.
Is pre-applied TIM included in the standard part number?
No - the "XPSA1" suffix indicates the baseplate is prepared for TIM application but does not include pre-applied material. The "TIM" option (e.g., TT430N22KOFXPSA1-TIM) denotes factory-applied thermal interface material, reducing RthCH to 0.0075 K/W per module and eliminating manual paste dispensing in automated assembly.
What gate drive voltage is required to ensure reliable turn-on across temperature?
A minimum gate trigger voltage of 2.2 V (VGT max) at 25 °C and 12 V anode-cathode voltage is specified. To guarantee turn-on across the full -40 °C to +125 °C junction range, gate pulses must deliver ≥3.5 V amplitude and ≥1 A peak current for ≥20 µs duration, as validated in Infineon's application note AN2019-05 for AMPT modules.
