Product details
Overview
T1190N14TOFVTXPSA1 from Infineon Technologies is a high-power phase-control thyristor designed for industrial AC power regulation in medium- to high-voltage line-commutated converters. It delivers 1190 A average on-state current at 85 °C case temperature, supports 1400 V repetitive peak off-state voltage (VDRM/VRRM), and withstands 25.5 kA non-repetitive surge current (ITSM) - enabling use in 3-phase rectifier bridges for steel mill drives and HVDC converter valves.
For engineers reviewing the T1190N14TOFVTXPSA1 datasheet, T1190N14TOFVTXPSA1 pinout, T1190N14TOFVTXPSA1 application, or T1190N14TOFVTXPSA1 equivalent, key selection criteria include its 125 °C maximum junction temperature, 200 A/µs critical di/dt rating, 1000 V/µs critical dv/dt capability, gate trigger current ≤250 mA, and two-sided clamped package requiring 16–32 kN mounting force.
Technical Context
This thyristor operates as a line-commutated switching device in phase-angle controlled rectifiers and inverters. Its design centers on robust thermal performance: 0.023 °C/W maximum junction-to-case thermal resistance with two-sided cooling, 240 µs typical turn-off time (tq), and validated operation across -40 °C to +125 °C case temperature range.
The device features a pressure-contact silicon pellet construction with auxiliary cathode terminal, enabling high-current conduction (2770 A RMS) and low on-state voltage drop (1.06 V at 1 kA, 2.05 V at 5.4 kA). Gate control is optimized for reliable triggering under high dv/dt stress, with VGD ≤0.2 V and IGD ≤10 mA at maximum junction temperature.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar phase-control thyristor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TT1190N14KOF | Same VDRM (1400 V) and ITAVM (1190 A), but uses TO-240AB package with integrated heat spreader and lower clamping force (12–24 kN). | Designed for bolt-down mounting without external pressure plates; less suitable for ultra-high-reliability stacked valve assemblies. | Select when simplified mechanical integration outweighs need for maximum surge margin and thermal symmetry. |
| T1230N14TOF | Higher ITAVM (1230 A at 85 °C) and ITSM (27 kA), but same TO-240AA package and thermal resistance (0.023 °C/W). | Offers 3.4% higher continuous current rating; identical footprint and cooling interface - direct upgrade where thermal headroom is constrained. | Select when upgrading legacy T1190N designs to increase power density without changing heatsink or clamping hardware. |

FAQ
What is the recommended gate drive circuit for T1190N14TOFVTXPSA1?
A pulse transformer or optocoupler-based gate driver delivering ≥1 A peak gate current for ≥20 µs is required to ensure reliable turn-on. The gate trigger voltage must exceed 2 V (VGT max), and the non-trigger voltage must remain below 0.2 V (VGD max) at maximum junction temperature to prevent false triggering under high dv/dt conditions.
Can T1190N14TOFVTXPSA1 be used in forced-commutated circuits?
No - this device is designed exclusively for line-commutated operation. Its 240 µs typical turn-off time (tq) and lack of gate turn-off capability make it unsuitable for chopper or PWM applications. Forced commutation requires GTOs or IGCTs with active gate control for both turn-on and turn-off.
What is the significance of the auxiliary cathode (terminal 5)?
The auxiliary cathode provides a dedicated, low-inductance reference point for gate drive circuitry. It stabilizes the gate-cathode voltage during rapid voltage transients (dv/dt), preventing spurious turn-on by isolating gate loop impedance from main current paths - critical in high-noise converter valve environments.
How does two-sided cooling affect thermal design?
Two-sided cooling halves the effective thermal path length, reducing RthJC to 0.023 °C/W. This allows 25–30% higher power dissipation versus single-sided mounting at the same case temperature, enabling compact heatsink designs in multi-thyristor stacks where axial space is constrained.
