Product details
Overview
TT190N18SOFHPSA1 from Infineon Technologies is a phase-control thyristor module designed for high-power AC line commutated switching in industrial power conversion systems. It delivers 190 A average on-state current (ITAVM) at TC = 85 °C, 1800 V repetitive peak off-state voltage (VDRM/VRRM), and 5200 A non-repetitive surge current (ITSM), with electrically insulated baseplate and solder-bond construction. It is used in soft starters for three-phase induction motors.
For engineers reviewing the TT190N18SOFHPSA1 datasheet, TT190N18SOFHPSA1 pinout, TT190N18SOFHPSA1 application, or TT190N18SOFHPSA1 equivalent, key selection criteria include junction-to-case thermal resistance (0.145 K/W), critical dv/dt rating (1000 V/µs), gate trigger current (≤145 mA), and RMS on-state current capability (275 A).
Technical Context
This dual-thyristor module operates in line-commutated phase-angle control mode, supporting 50/60 Hz AC mains with conduction angles from 30° to 180°. Its 125 °C maximum junction temperature, 0.9 mΩ slope resistance, and 0.85 V threshold voltage enable stable conduction under high-current transient loads.
The module integrates two anti-parallel thyristor dies in an industrial-standard package with Al₂O₃-based electrical isolation (3.6 kV insulation test voltage, 1 min). Gate drive requires ≤2.5 V trigger voltage and tolerates up to 0.25 V non-trigger voltage at 0.5×VDRM.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDRM / VRRM | 1800 V - Maximum repetitive blocking voltage per thyristor arm, enabling use in 1000 V AC line applications with safety margin. |
| ITAVM (TC = 85 °C) | 190 A - Continuous average on-state current per arm, defining steady-state thermal design basis for heatsink sizing. |
| ITSM (10 ms) | 5200 A - Non-repetitive surge current capability, supporting motor inrush and short-circuit fault ride-through. |
| RthJC | 0.145 K/W - Junction-to-case thermal resistance per module, directly determining ΔTjc under power loss conditions. |
| (dv/dt)cr | 1000 V/µs - Minimum critical rate-of-rise of off-state voltage before spurious turn-on, requiring snubber design for inductive loads. |
| VTO / rT | 0.85 V / 0.9 mΩ - Threshold voltage and slope resistance, jointly defining forward conduction loss profile at rated current. |
| IGT / VGT | ≤145 mA / ≤2.5 V - Maximum gate trigger current and voltage at 25 °C, specifying minimum driver strength required. |
Pinout & Package
TT190N18SOFHPSA1 uses an industrial-standard press-pack-style module housing with electrically insulated baseplate (Al₂O₃ ceramic), M1/M2 screw terminals, and DIN 46244 A-type control terminals (2.8 × 0.8 mm). Total weight: 165 g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A1 (Anode 1) | Main anode of first thyristor | High-current AC line input terminal for one arm; rated for 190 A continuous, 5200 A surge. |
| K1 (Cathode 1) | Main cathode of first thyristor | Output terminal for first thyristor arm; connects to load or bridge midpoint in B2/B6 configurations. |
| A2 (Anode 2) | Main anode of second thyristor | Second high-current AC line terminal; forms anti-parallel pair with K1 for bidirectional conduction. |
| K2 (Cathode 2) | Main cathode of second thyristor | Complementary output terminal; enables full-wave phase control in single-phase or three-phase bridge topologies. |
| G1, K1G | Gate and cathode reference for first thyristor | Isolated low-power control interface; requires ≤2.5 V, ≤145 mA trigger pulse with defined di/dt. |
| G2, K2G | Gate and cathode reference for second thyristor | Independent gate drive path; allows separate firing angle control for each thyristor arm in asymmetrical operation. |
Key Features
| Feature | Design Value |
|---|---|
| Solder-bond die attachment | Eliminates wire bonds and reduces thermal cycling fatigue, improving long-term reliability in high-dI/dt industrial environments. |
| Electrically insulated baseplate | Al₂O₃ ceramic isolation rated to 3.6 kV RMS (1 sec), enabling direct mounting to grounded heatsinks without additional insulation. |
| 100 A/µs critical di/dt | Ensures robust turn-on under fast-rising load currents without false triggering, critical for motor starter transients. |
| 125 °C max junction temperature | Supports operation in high-ambient industrial enclosures while maintaining 190 A ITAVM derating down to TC = 85 °C. |
| 10 mm creepage distance | Meets IEC 61140 Class I basic insulation requirements for 1000 V AC systems with pollution degree 2. |

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 |
|---|---|---|---|
| TD190N18SOF | Single-thyristor version (no anti-parallel pair); same VDRM, ITAVM, and thermal specs. | Requires external anti-parallel device for AC switching; not suitable for bidirectional phase control without added components. | Select when only unidirectional DC or half-wave AC control is needed, reducing system complexity and cost. |
| TT240N18SOF | Higher ITAVM (240 A), higher ITSM (6000 A), identical VDRM and package footprint. | Supports heavier motor loads and longer overload durations; requires larger heatsink due to increased power dissipation. | Select when upgrading existing TT190N18SOF designs for higher continuous current or extended surge margin. |
Compared with TD190N18SOF and TT240N18SOF, TT190N18SOFHPSA1 provides optimal balance of bidirectional AC control capability, thermal performance, and industrial packaging-making it ideal for soft starters and static switches where dual-arm integration reduces board space and interconnect losses.

FAQ
What is the maximum allowable case temperature for continuous operation?
The maximum allowable case temperature (TC) is +125 °C, but the rated average on-state current ITAVM = 190 A is specified at TC = 85 °C. Operation above 85 °C requires linear derating per the datasheet's TC vs. ITAVM curve, with zero current allowed at 125 °C case temperature.
Does TT190N18SOFHPSA1 require forced air cooling?
No forced air cooling is mandatory; natural convection is viable with appropriately sized heatsinks. The module's RthJC = 0.145 K/W and RthCH = 0.04 K/W per module allow thermal design using standard aluminum extrusions, provided total RthCA (case-to-ambient) remains ≤0.25 K/W for full 190 A operation at 85 °C case temperature.
Can this module be used in three-phase full-wave bridge (B6) configurations?
Yes - TT190N18SOFHPSA1 contains two anti-parallel thyristor arms, making it suitable as one leg of a three-phase B6 bridge. Two modules (totaling four arms) are required per B6 rectifier; each arm handles one half-wave conduction path with synchronized gate timing.
What gate drive voltage and current are required for reliable triggering?
A gate trigger pulse of ≤2.5 V and ≤145 mA at 25 °C is sufficient. For robust operation across temperature, drivers should deliver ≥1.5 A peak current for ≥20 µs pulses to ensure latching (IL ≤ 400 mA) and overcome worst-case VGT drift at 125 °C junction temperature.
