Product details
Overview
TD430N22KOFTIMHPSA1 from Infineon Technologies is a press-pack, double-sided cooled, phase-control thyristor module rated for 2200 V repetitive peak off-state voltage (VDRM/VRRM), 430 A average on-state current (ITAVM at TC = 85 °C), and 14 kA non-repetitive surge current (ITSM). 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 TD430N22KOFTIMHPSA1 datasheet, TD430N22KOFTIMHPSA1 pinout, TD430N22KOFTIMHPSA1 application, or TD430N22KOFTIMHPSA1 equivalent, key selection criteria include junction-to-case thermal resistance (0.062 K/W per module), critical dv/dt rating (1000 V/µs), gate trigger voltage (≤2.2 V), and isolation test voltage (3.6 kV for 1 sec).
Technical Context
This thyristor module implements a dual-arm, anti-parallel configuration optimized for AC phase-angle control in high-power industrial converters. Its pressure-contact construction ensures stable thermal and electrical performance under cyclic load stress, with validated turn-off time (tq = 300 µs typical) and critical rate-of-rise parameters (diT/dt)cr = 150 A/µs and (dvD/dt)cr = 1000 V/µs.
Designed for forced-air or liquid-cooled heatsink mounting, it supports DC, 60°–180° conduction angle operation with derated ITAVM up to 800 A RMS (ITRMSM) and thermal impedance ZthJC modeled analytically across transient durations from 0.00076 s to 3.12 s.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDRM / VRRM | 2200 V - Maximum repetitive blocking voltage in forward/reverse direction, enabling use in 1.1 kV AC line applications with safety margin. |
| ITAVM (TC = 85 °C) | 430 A - Continuous average on-state current per arm at case temperature 85 °C, defining steady-state power handling capability. |
| ITSM (10 ms) | 14000 A - Non-repetitive surge current rating, supporting short-circuit withstand in motor drive crowbar protection. |

Pinout & Package
TD430N22KOFTIMHPSA1 is housed in an industrial-standard press-pack module with electrically insulated AlN ceramic baseplate (60 mm × 60 mm footprint), dual-side cooling interface, and M1 (6 Nm) mechanical mounting screws plus M2 (12 Nm) terminal bolts. Control terminals conform to DIN 46244 A (2.8 × 0.8 mm flat blade).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (A1) | Main current terminal - Arm 1 anode | High-current path for one thyristor arm; requires low-inductance busbar connection and torque-controlled M2 fastening. |
| Cathode (K1) | Main current terminal - Arm 1 cathode | Completes current loop for Arm 1; shares thermal path with baseplate and must be thermally coupled to heatsink via TIM layer. |
| Anode (A2) | Main current terminal - Arm 2 anode | Second thyristor arm configured anti-parallel to Arm 1 for bidirectional AC control in bridge topologies. |
| Cathode (K2) | Main current terminal - Arm 2 cathode | Enables full-wave phase control; both arms share common insulated baseplate but are electrically isolated from each other and ground. |
| Gate (G1) | Control input - Arm 1 gate | Low-energy trigger input (≤250 mA IGT, ≤2.2 V VGT); requires isolated gate driver with <4 µs delay (tgd max) for synchronized firing. |
| Gate (G2) | Control input - Arm 2 gate | Independent gate terminal for second arm; enables independent or complementary triggering in asymmetrical control schemes. |
| Cathode (K) | Reference node - Common cathode reference | Shared cathode reference point for gate drivers; not a current-carrying terminal but essential for referenced gate biasing. |
Key Features
| Feature | Design Value |
|---|---|
| Pressure contact technology | Eliminates wire bonds and solder layers, delivering >10⁶ thermal cycles reliability and stable RthJC over lifetime without degradation. |
| Pre-applied thermal interface material (TIM) | Reduces RthCH by 25% vs. bare surface (0.0075 K/W vs. 0.010 K/W), enabling faster thermal response and lower peak junction temperature during transients. |
| Electrically insulated baseplate (AlN) | Provides 3.6 kV isolation (1 sec) and Class I basic insulation per IEC 61140, removing need for additional isolation hardware in grounded heatsink systems. |
| Advanced Medium Power Technology (AMPT) | Optimizes carrier lifetime and emitter geometry to achieve 0.95 V threshold voltage (VT0) and 0.45 mΩ slope resistance (rT) at 125 °C junction. |
| Validated commutation turn-off time (tq) | 300 µs typical at Tvj = 125 °C, enabling reliable forced-commutated operation in static VAR compensators and active rectifiers. |

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 |
|---|---|---|---|
| TT430N22KOF | No pre-applied TIM; RthCH = 0.010 K/W (vs. 0.0075 K/W with TIM); identical VDRM, ITAVM, and package dimensions. | Requires user-applied thermal paste; less suitable for high-volume automated assembly where TIM consistency is critical. | Select TT430N22KOF only when TIM rework or custom thermal interface is required; otherwise TD430N22KOFTIMHPSA1 offers superior thermal repeatability. |
| TD500N22KOF | Higher ITAVM = 500 A (TC = 85 °C); same VDRM = 2200 V; RthJC = 0.053 K/W; larger mechanical footprint (65 mm × 65 mm). | Supports higher continuous current in space-constrained designs where thermal margin is prioritized over board area. | Choose TD500N22KOF when system-level ITAVM exceeds 430 A and heatsink capacity permits larger module footprint; not drop-in compatible due to mounting hole pattern change. |
Compared with TT430N22KOF, TD430N22KOFTIMHPSA1 delivers lower thermal resistance and factory-consistent TIM application, while TD500N22KOF trades size for +16% current rating-making the original optimal for cost-sensitive, high-volume soft starter modules requiring proven TIM integration.

FAQ
What is the maximum allowable junction temperature for TD430N22KOFTIMHPSA1?
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, calculated peak junction temperature remains ≤125 °C using the provided ZthJC transient model and RthCH values.
Does TD430N22KOFTIMHPSA1 require external snubbers in standard phase-control applications?
Snubbers are not mandatory due to its high (dvD/dt)cr rating of 1000 V/µs, but are recommended for inductive loads with rapid voltage transients exceeding 500 V/µs. The module's validated turn-off time (tq = 300 µs) and gate non-trigger voltage (VGD ≤ 0.25 V) support snubberless operation only when circuit dv/dt stays below 70% of (dvD/dt)cr with proper gate drive timing.
Can TD430N22KOFTIMHPSA1 be used in single-phase versus three-phase configurations?
Yes-it supports both. In single-phase, it operates as a back-to-back pair (A1–K1 and A2–K2) for full-wave AC control. In three-phase, two modules configure a six-pulse (B6) bridge, with each arm handling up to 430 A ITAVM. Derating curves in the datasheet specify ITAVM vs. conduction angle and cooling conditions for both topologies.
What is the creepage distance and why does it matter for this module?
The creepage distance is 19 mm, measured across the insulated AlN baseplate between main terminals and mounting surface. This value satisfies reinforced insulation requirements for Pollution Degree 2 environments per IEC 60664-1, ensuring safe operation in industrial enclosures with dust and occasional condensation without risk of surface tracking or flashover.
