Product details
Overview
T1930N34TOFVTXPSA1 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 3400 V repetitive peak off-state voltage (VDRM/VRRM), 4200 A RMS on-state current (ITRMS), and 2180 A average on-state current at 85 °C case temperature-enabling robust operation in HVDC converter valves, static VAR compensators, and rolling mill drive rectifiers.
For engineers reviewing the T1930N34TOFVTXPSA1 datasheet, T1930N34TOFVTXPSA1 pinout, T1930N34TOFVTXPSA1 application, or T1930N34TOFVTXPSA1 equivalent, key selection criteria include its 125 °C maximum junction temperature, 150 A/µs critical di/dt rating, 1000 V/µs critical dv/dt capability, gate trigger current ≤300 mA, and two-sided cooling-compatible TO-247-style press-pack package with auxiliary cathode terminal.
Technical Context
This thyristor operates as a line-commutated, gate-controlled semiconductor switch in phase-angle controlled rectification circuits. Its design supports forced commutation via external circuitry and requires precise gate pulse timing (tgd ≤3 µs) and minimum latching current (IL ≤1500 mA) to ensure reliable turn-on under high di/dt conditions.
Thermal performance is defined by a 0.0078 °C/W max junction-to-case thermal resistance (two-sided cooling, θ = 180° sin), transient thermal impedance modeling (ZthJC analytical elements provided), and derating curves for sinusoidal and rectangular currents across conduction angles from 30° to 180°.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDRM / VRRM | 3400 V - Maximum repetitive blocking voltage in forward/reverse direction at Tvj max, enabling use in 3.3 kV-class AC systems |
| ITRMS | 4920 A - RMS on-state current rating defines continuous thermal loading capacity under real-world AC waveforms |
| ITAVM @ TC=85°C | 2180 A - Average on-state current limit at 85 °C case temperature, used for steady-state thermal design |
| (diT/dt)cr | 150 A/µs - Minimum required rate of rise of on-state current to avoid localized hot-spot formation during turn-on |
| (dvD/dt)cr | 1000 V/µs - Critical off-state voltage rise rate threshold beyond which spurious turn-on may occur without gate assist |
| RthJC (two-sided) | 0.0078 °C/W - Junction-to-case thermal resistance under optimal two-sided heatsink mounting, directly impacts thermal margin |
| vT @ iT=8 kA | 2.90 V - On-state voltage drop at full-rated surge current, used to calculate conduction losses in worst-case scenarios |
Pinout & Package
The T1930N34TOFVTXPSA1 uses a press-pack, double-sided cooled, stud-mount package compliant with Infineon's TO-247-style mechanical outline (see Annex, Page 3). It features four terminals: Anode (1), Cathode (2), Gate (4), and Auxiliary Cathode (5), with clamping force range 42–95 kN.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (1) | Main current entry terminal | Carries full load current into device; requires high-pressure contact and thermally conductive interface to heatsink |
| Cathode (2) | Main current exit terminal | Primary cathode path for on-state conduction; electrically and thermally coupled to main heatsink surface |
| Gate (4) | Control input | Low-energy trigger terminal requiring ≥1.6 A gate pulse with diG/dt ≥1.6 A/µs to ensure reliable turn-on |
| Auxiliary Cathode (5) | Secondary cathode reference | Provides isolated low-inductance return path for gate drive and sensing, reducing noise coupling in high-di/dt applications |
Key Features
| Feature | Design Value |
|---|---|
| High VDRM/VRRM grading | 3400 V rating enables direct integration into 3.3 kV AC distribution and traction rectifier systems without series stacking |
| Two-sided cooling support | 0.0078 °C/W RthJC allows symmetric thermal management using dual heatsinks, improving reliability in high-power converters |
| Robust dv/dt immunity | 1000 V/µs critical off-state voltage rise rate prevents false triggering in noisy industrial EMI environments |
| Low on-state slope resistance | 0.20 mΩ rT minimizes conduction loss variation across operating current range, supporting stable thermal behavior |
| Gate-triggered latching | 1500 mA IL ensures secure turn-on even under high junction temperature and low gate drive margin conditions |

Equivalent & Alternatives
The following parts are listed as comparable options for similar phase-control thyristor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TT1930N34KOF | Same VDRM/VRRM (3400 V) and ITRMS (4920 A), but rated for 110 °C max junction temperature and uses different gate structure (K-type). | Designed for lower-cost, non-AEC-Q101 qualified industrial drives; lacks auxiliary cathode terminal. | Select when gate noise immunity is less critical and cost sensitivity outweighs need for auxiliary cathode isolation. |
| T1930N34TOFVTXPSA2 | Identical electrical specs and package, but with enhanced gate trigger sensitivity (IGT ≤250 mA vs. 300 mA) and tighter VGT tolerance (≤2.5 V). | Targeted at high-reliability aerospace and defense converters where gate drive margin must exceed 20%. | Select when driving from low-power isolated gate drivers or operating near thermal limits where reduced IGT improves turn-on consistency. |
Compared with TT1930N34KOF and T1930N34TOFVTXPSA2, the T1930N34TOFVTXPSA1 uniquely balances high dv/dt immunity (1000 V/µs), auxiliary cathode isolation, and AEC-Q101-aligned qualification-making it optimal for safety-critical grid infrastructure and traction systems demanding long-term thermal stability and EMI resilience.

FAQ
What is the maximum allowable clamping force for T1930N34TOFVTXPSA1?
The device requires mechanical mounting with a clamping force between 42 kN and 95 kN, as specified in the mechanical properties section of the datasheet. Exceeding 95 kN risks silicon die fracture or metallization damage, while forces below 42 kN increase thermal resistance and risk thermal runaway under full-load operation.
Does T1930N34TOFVTXPSA1 support forced commutation?
No-it is a line-commutated thyristor, meaning turn-off relies on natural current zero-crossing in the AC supply. Forced commutation requires external circuitry (e.g., commutation chokes or capacitor networks) and is not intrinsic to the device; its tq (turn-off time) of 450 µs is specified under standardized line-commutated test conditions.
Is auxiliary cathode (Terminal 5) electrically isolated from main cathode (Terminal 2)?
Yes-Terminal 5 is a dedicated, low-inductance auxiliary cathode referenced separately from Terminal 2. It is intended for gate driver return and sensing circuits to minimize ground loop noise and improve dv/dt immunity, and must not be shorted to Terminal 2 in layout.
What gate drive parameters ensure reliable turn-on at Tvj = 125 °C?
At maximum junction temperature, reliable turn-on requires gate pulses with peak current ≥1.6 A, diG/dt ≥1.6 A/µs, pulse width ≥20 µs, and gate trigger voltage ≤3 V. The datasheet specifies IGT ≤300 mA and VGT ≤3 V at 25 °C, but derating is mandatory at elevated temperature to maintain latching margin.
