Product details
Overview
TT190N16SOFHPSA2 from Infineon Technologies is a phase-control thyristor module configured as a dual-arm (two-chip) AC power switching device with 1600 V repetitive peak off-state voltage, 190 A average on-state current at 85 °C case temperature, and electrically insulated Al₂O₃ baseplate. It delivers 5200 A non-repetitive surge current capability and is designed for industrial AC power control in soft starters and UPS rectifiers.
For engineers reviewing the TT190N16SOFHPSA2 datasheet, TT190N16SOFHPSA2 pinout, TT190N16SOFHPSA2 application, or TT190N16SOFHPSA2 equivalent, key selection criteria include verified thermal resistance (RthJC = 0.145 K/W per module), gate trigger parameters (IGT ≤ 145 mA, VGT ≤ 2.5 V), and isolation rating (3.6 kV RMS/1 sec).
Technical Context
This dual-thyristor module operates in phase-angle controlled AC circuits, where precise gate timing governs conduction angle to regulate RMS output voltage and current. Its 125 °C maximum junction temperature and 0.9 mΩ slope resistance enable high-efficiency power handling under continuous 190 A DC-equivalent load conditions.
The module integrates solder-bond interconnect technology and Class 1 basic insulation (Al₂O₃ ceramic), supporting safe operation in grounded-heatsink configurations. Critical dv/dt (1000 V/µs) and di/dt (100 A/µs) ratings ensure reliable commutation in inductive drive and UPS applications without spurious turn-on.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDRM / VRRM | 1600 V - Maximum repetitive blocking voltage in forward/reverse direction; defines AC line voltage compatibility up to 1150 V RMS. |
| ITAVM (TC = 85 °C) | 190 A - Continuous average on-state current per module; sets thermal design baseline for heatsink sizing. |
| ITSM (10 ms) | 5200 A - Non-repetitive surge current; supports motor inrush and short-circuit withstand in soft starter designs. |
| RthJC | 0.145 K/W - Junction-to-case thermal resistance per module; enables direct thermal modeling for forced-air or liquid-cooled systems. |
| V(TO) / rT | 0.85 V / 0.9 mΩ - Threshold voltage and slope resistance; determines conduction loss profile (PTAV ≈ ITAV² × rT + ITAV × V(TO)). |
| VISOL (1 sec) | 3.6 kV RMS - Isolation test voltage; certifies safety compliance for industrial equipment operating at 690 V AC mains. |
| (dv/dt)cr | 1000 V/µs - Critical rate of rise of off-state voltage; prevents false triggering in high-noise rectifier or static switch environments. |
Pinout & Package
TT190N16SOFHPSA2 uses an industry-standard isolated package with solder-bond construction and Al₂O₃ ceramic baseplate. Mechanical mounting uses M1 screws (5 Nm ±15%), electrical terminals use M2 screws (5 Nm ±10%), and control terminals conform to DIN 46244 A (2.8 × 0.8 mm).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A1 (Anode 1) | Main current terminal - Arm 1 anode | Carries full-phase current in one thyristor arm; connected to AC line input in bridge configurations. |
| K1 (Cathode 1) | Main current terminal - Arm 1 cathode | Output node for Arm 1; ties to load or common DC bus in half-controlled rectifier topologies. |
| A2 (Anode 2) | Main current terminal - Arm 2 anode | Second thyristor arm anode; enables dual-phase or full-wave AC control in B2/B6 bridge layouts. |
| K2 (Cathode 2) | Main current terminal - Arm 2 cathode | Second arm output; used for complementary conduction in six-pulse rectifier or static switch back-to-back arrangements. |
| G1, K1G | Gate control - Arm 1 | Isolated gate drive interface for Arm 1; requires ≤2.5 V trigger voltage and ≥145 mA pulse current. |
| G2, K2G | Gate control - Arm 2 | Independent gate interface for Arm 2; supports asynchronous or synchronized firing in multi-phase control. |
Key Features
| Feature | Design Value |
|---|---|
| Solder-bond interconnect | Eliminates wire bonds to improve thermal cycling reliability and reduce parasitic inductance in high-di/dt switching. |
| Electrically insulated baseplate | Al₂O₃ ceramic (Class 1 insulation) enables direct mounting to grounded heatsinks without additional isolation hardware. |
| Dual-arm thyristor integration | Two matched thyristor chips in single package simplify PCB layout and ensure balanced current sharing in bridge rectifiers. |
| High dv/dt immunity | 1000 V/µs critical off-state voltage rise rate prevents false triggering in noisy industrial EMI environments. |
| Low conduction loss | 0.85 V threshold + 0.9 mΩ slope resistance yields <1.52 V on-state drop at 500 A, reducing thermal stress in high-current UPS stages. |

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 |
|---|---|---|---|
| TD190N16SOF | Single-arm configuration; same VDRM, ITAVM, RthJC, but no second thyristor arm. | Requires two modules for B6 rectifier; increases footprint and gate drive complexity vs. dual-arm TT190N16SOFHPSA2. | Select when modular redundancy or separate arm control is required; avoid if space-constrained dual-arm integration is preferred. |
| TT240N16SOF | Higher ITAVM (240 A), larger RthJC (0.115 K/W), identical VDRM and isolation rating. | Supports higher continuous current in same footprint; suitable for upgraded soft starters or higher-power UPS systems. | Choose for future-proofing or thermal headroom; verify gate drive compatibility and heatsink retention force for heavier module mass. |
Compared with TD190N16SOF and TT240N16SOF, TT190N16SOFHPSA2 offers optimal balance of dual-arm integration, 190 A rating, and 0.145 K/W thermal resistance-making it ideal for space-constrained B2/B6 rectifiers and static switches where gate synchronization and thermal predictability are critical.

FAQ
What is the maximum allowable case temperature for continuous operation?
The maximum case temperature (Tc op) is rated from –40 °C to +125 °C. For continuous 190 A average current (ITAVM), the case must not exceed 85 °C to maintain specified thermal resistance and lifetime reliability. Derating is required above 85 °C per the ITAVM vs. TC curve in the datasheet.
Does TT190N16SOFHPSA2 require external snubbers in standard rectifier applications?
Snubbers are not mandatory for typical B2 or B6 rectifier operation due to its 1000 V/µs (dv/dt)cr rating and low stored charge. However, RC snubbers are recommended for highly inductive loads or when operating near maximum VDRM to suppress voltage overshoot during commutation.
How is gate drive isolation implemented for this module?
Gate terminals (G1/K1G and G2/K2G) are electrically isolated from the main power terminals and baseplate. The module relies on externally supplied isolated gate drivers-typically transformer-coupled or optocoupled-to meet the 3.6 kV isolation requirement and prevent ground-loop interference in multi-module systems.
Can TT190N16SOFHPSA2 be used in parallel configurations?
Parallel operation is not recommended. The module is designed as a self-contained dual-arm unit with matched chip characteristics. Parallel connection of multiple modules introduces current-sharing imbalance risks due to parameter tolerances and thermal coupling differences, violating Infineon's application guidance for this series.
