Product details
Overview
T1960N22TOFVTXPSA1 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 1960 A average on-state current at 85 °C case temperature, 2200 V repetitive peak off-state voltage (VDRM/VRRM), and supports 40 kA non-repetitive surge current (ITSM) with 8000 × 10³ A²s I²t rating - enabling robust operation in HVDC converter valves, traction rectifiers, and static VAR compensators.
For engineers reviewing the T1960N22TOFVTXPSA1 datasheet, T1960N22TOFVTXPSA1 pinout, T1960N22TOFVTXPSA1 application, or T1960N22TOFVTXPSA1 equivalent, key selection criteria include verified gate trigger current (≤300 mA), critical dv/dt capability (1000 V/µs), junction-to-case thermal resistance (0.0125 °C/W two-sided), and validated 300 µs turn-off time under line-commutated conditions.
Technical Context
This thyristor operates as a bidirectional, gate-controlled, line-commutated switching device in series-connected valve stacks. Its design centers on high di/dt immunity (200 A/µs critical on-state rise rate) and high dv/dt blocking (1000 V/µs), ensuring reliable commutation in 50/60 Hz AC systems with inductive loads and fast voltage transients.
It features a silicon pellet with pressure-contact construction, requiring precise clamping force (30–65 kN) and two-sided heatsinking to maintain junction temperature ≤125 °C. The auxiliary cathode terminal enables accurate gate control and dynamic parameter measurement, distinguishing it from standard two-terminal thyristors.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDRM / VRRM | 2200 V - Maximum repetitive blocking voltage in forward/reverse direction; defines usable AC line voltage range up to 1500 V RMS. |
| ITAVM (TC = 85 °C) | 1960 A - Continuous DC or sinusoidal conduction current at rated case temperature; sets base thermal design load. |
| ITRMS | 4490 A - RMS on-state current rating; determines conductor sizing and loss calculation for real-world waveform duty cycles. |
| ITSM (10 ms) | 40000 A - Non-repetitive surge current capacity; validates short-circuit withstand in grid-tied systems. |
| tq (typ.) | 300 µs - Circuit commutated turn-off time at max junction temp; constrains minimum commutation circuit time constant. |
| (dvD/dt)cr | 1000 V/µs - Critical rate of rise of off-state voltage; specifies required snubber design to prevent false triggering. |
| RthJC (two-sided) | 0.0125 °C/W - Junction-to-case thermal resistance; defines minimum heatsink interface performance for thermal management. |
Pinout & Package
Package: TO-220-compatible press-pack module with isolated anode/cathode terminals and dual gate connections (flat and round). Requires mechanical clamping (30–65 kN) and two-sided thermal interface for rated performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (1) | Main current entry terminal | Carries full load current into device; must be thermally and electrically bonded to heatsink side A. |
| Cathode (2) | Main current exit terminal | Completes main conduction path; bonded to heatsink side B; shares thermal path with auxiliary cathode. |
| Gate (4) | Trigger control input | Accepts ≥1.6 A pulse to initiate conduction; flat or round contact per AMP 60598 spec; sensitive to dv/dt. |
| Auxiliary Cathode (5) | Reference node for gate timing | Provides low-inductance return path for gate drive; enables accurate tgd measurement and stable triggering. |
Key Features
| Feature | Design Value |
|---|---|
| Pressure-contact Si pellet | Enables scalable current handling without wire bonds; supports >4 kA ITSM and eliminates bond-wire fatigue failure modes. |
| Two-sided cooling interface | Reduces RthJC to 0.0125 °C/W - cuts thermal resistance by ~40% vs. single-sided mounting, allowing higher ITAV at same TC. |
| High dv/dt immunity (1000 V/µs) | Permits direct use in high-dV/dt environments (e.g., transformer-fed rectifiers) without external dv/dt snubbers. |
| Low on-state voltage (1.2 V @ 2 kA) | Minimizes conduction losses: <2.4 kW loss at 2 kA, improving system efficiency and reducing heatsink size. |
| Validated tq = 300 µs | Guarantees reliable forced commutation in 50 Hz systems with margin for aging and temperature drift. |

FAQ
What is the maximum allowable clamping force for T1960N22TOFVTXPSA1?
The device requires a mechanical clamping force between 30 kN and 65 kN to ensure optimal thermal contact and electrical integrity across the pressure-contact silicon pellet. Exceeding 65 kN risks die fracture or metallization damage, while forces below 30 kN increase RthJC beyond specification and risk thermal runaway under full-load operation.
Does T1960N22TOFVTXPSA1 support forced commutation?
No - this is a line-commutated thyristor optimized for natural current-zero crossing turn-off in AC systems. It lacks integrated gate-turn-off (GTO) capability or self-commutating structure. Forced commutation requires external LC snubber networks or auxiliary circuits, and tq = 300 µs reflects its validated performance only under line-commutated conditions.
Can T1960N22TOFVTXPSA1 be used in parallel configurations?
Yes, but only with active current-sharing techniques: matched gate drive timing (≤1 µs skew), symmetrical busbar layout, and individual current-sensing feedback. Static sharing is not guaranteed due to parameter spread in VT and di/dt capability; parallel operation without balancing increases risk of thermal runaway in one device.
What is the significance of the auxiliary cathode (terminal 5)?
The auxiliary cathode provides a dedicated, low-inductance reference point for gate drive return and dynamic characterization. It isolates gate loop inductance from main cathode current paths, enabling precise tgd measurement and stable triggering under high di/dt conditions - essential for reproducible firing in multi-thyristor valve stacks.
