Product details
Overview
TD700N22KOFTIMHPSA1 from Infineon Technologies is a phase-control thyristor module designed for high-power AC line switching in industrial power electronics. It delivers 700 A average on-state current (ITAVM) at TC = 85°C, 2200 V repetitive peak off-state voltage (VDRM/VRRM), and features pressure-contact die attachment for thermal and mechanical robustness. It is used in soft starters, static switches, and UPS rectifiers where high surge immunity and reliable forced-commutation capability are required.
For engineers reviewing the TD700N22KOFTIMHPSA1 datasheet, TD700N22KOFTIMHPSA1 pinout, TD700N22KOFTIMHPSA1 application, or TD700N22KOFTIMHPSA1 equivalent, key selection criteria include junction-to-case thermal resistance (0.046 K/W), critical dv/dt rating (1000 V/µs), gate trigger threshold (≤2.2 V), and pre-applied TIM integration for simplified thermal interface assembly.
Technical Context
This dual-thyristor module implements a press-pack construction with electrically insulated baseplate and AlN ceramic isolation (Class I, IEC 61140). Its gate-controlled turn-on behavior supports precise phase-angle control in AC line applications, with validated commutated turn-off time (tq = 260 µs typ.) under defined dv/dt and di/dt conditions.
The device operates across -40°C to +135°C case temperature range and supports both DC and sinusoidal conduction angles (Θ = 30°–180°). Its transient thermal impedance ZthJC is analytically modeled using seven RC network elements, enabling accurate loss and temperature prediction in dynamic load profiles.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDRM / VRRM | 2200 V - Maximum repetitive blocking voltage per thyristor arm, defining safe AC line voltage class (e.g., 1.1 kV RMS systems). |
| ITAVM (TC = 85°C) | 700 A - Continuous average on-state current per arm, specifying steady-state power handling with heatsink cooling. |
| ITSM (10 ms) | 20400 A - Non-repetitive surge current capability, enabling short-circuit ride-through in motor drive and crowbar protection. |
| RthJC (per arm) | 0.046 K/W - Junction-to-case thermal resistance, directly determining maximum allowable power dissipation at given ΔT. |
| (dvD/dt)cr | 1000 V/µs - Minimum critical rate-of-rise of off-state voltage before spurious turn-on, critical for snubber design. |
| VGT max | 2.2 V - Maximum gate trigger voltage at 25°C, setting minimum driver output compliance for reliable firing. |
| tq (commutated) | 260 µs typ. - Time required for natural or forced commutation, constraining maximum operating frequency in phase-control topologies. |
Pinout & Package
TD700N22KOFTIMHPSA1 uses an industrial-standard press-pack module package with 60 mm baseplate, electrically insulated via AlN ceramic, and mechanical mounting per DIN 46244 A (2.8 × 0.8 mm control terminals). The module contains two anti-parallel thyristor arms sharing common cathode/anode terminals.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A1 / K2 | Anode of Arm 1 / Cathode of Arm 2 | Main power terminal for one thyristor arm; forms common connection point in back-to-back configuration. |
| K1 / A2 | Cathode of Arm 1 / Anode of Arm 2 | Main power terminal for second arm; enables bidirectional AC conduction when paired with A1/K2. |
| G1, K1 | Gate and cathode of Arm 1 | Isolated gate drive interface for Arm 1; requires ≤2.2 V trigger voltage and ≥250 mA trigger current. |
| G2, K2 | Gate and cathode of Arm 2 | Independent gate drive interface for Arm 2; electrically isolated from G1/K1 for differential control. |
| Baseplate | Thermal & electrical reference plane | Electrically insulated (3.6 kV RMS, 1 sec), thermally conductive surface for heatsink mounting with pre-applied TIM. |
Key Features
| Feature | Design Value |
|---|---|
| Pressure contact die attachment | Eliminates wire bonds and solder layers, improving thermal cycling endurance (>10⁵ cycles) and reducing RthJC drift over lifetime. |
| Pre-applied thermal interface material (TIM) | Reduces effective RthCH by 25% vs. bare metal interface (0.0075 K/W vs. 0.01 K/W), lowering thermal design margin requirements. |
| Advanced Medium Power Technology (AMPT) | Optimized silicon structure delivering 0.85 V threshold voltage and 0.35 mΩ slope resistance for low conduction losses at 1500 A. |

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 |
|---|---|---|---|
| TT700N22KOF | No pre-applied TIM; requires external thermal paste; identical electrical specs and package footprint. | Suitable for designs with custom TIM selection or rework requirements; higher assembly process variability. | Select TT700N22KOF only when TIM specification, reworkability, or cost sensitivity outweighs thermal interface consistency. |
| TD700N22KOF | Lacks TIM layer and insulated baseplate; baseplate is electrically conductive; otherwise matches core ratings. | Requires additional isolation hardware (e.g., mica washers) and careful grounding layout; lower system-level insulation test margin. | Choose TD700N22KOF only in cost-constrained, non-safety-critical applications where baseplate isolation is handled externally. |
Compared with TT700N22KOF and TD700N22KOF, TD700N22KOFTIMHPSA1 provides guaranteed thermal interface performance and Class I isolation out-of-box-reducing qualification time, eliminating TIM application variability, and simplifying safety-compliant mechanical integration in industrial UPS and soft starter designs.

FAQ
What is the maximum allowable junction temperature for TD700N22KOFTIMHPSA1?
The maximum junction temperature (Tvj max) is 135°C, as specified in the Infineon technical information document revision 3.6. This rating applies under all operating conditions including repetitive and non-repetitive surge events. Thermal design must ensure that instantaneous junction temperature remains below this limit, using the provided ZthJC transient thermal impedance model and measured case temperature.
Does TD700N22KOFTIMHPSA1 require external snubbers in standard phase-control operation?
Yes - due to its (dvD/dt)cr rating of 1000 V/µs, external RC snubbers are recommended for inductive loads or long cable runs to prevent false triggering. The required snubber values depend on load inductance and expected dv/dt transients; typical designs use 0.1 µF/100 Ω per arm for 50 Hz motor control applications with L/R > 10 ms.
Can TD700N22KOFTIMHPSA1 be used in parallel configurations?
No - this module is not characterized or qualified for parallel operation. Its pressure-contact construction and gate drive characteristics are optimized for single-module use in dual-arm topologies. Parallel connection would risk current imbalance, thermal runaway, and premature failure due to mismatched dynamic parameters and uncontrolled thermal coupling.
What is the creepage distance and insulation rating of the baseplate?
The creepage distance is 19 mm, and the baseplate provides basic insulation per IEC 61140 Class I. It passes 3.6 kV RMS insulation testing for 1 second and 3.0 kV RMS for 1 minute. This allows direct mounting to grounded heatsinks without supplemental isolation, meeting EN 62109 and UL 62368-1 requirements for industrial power equipment.
