Product details
Overview
T1930N38TOFVTXPSA1 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 3800 V repetitive peak off-state voltage (VDRM/VRRM), 4920 A RMS on-state current (ITRMS), and 40 kA non-repetitive surge current (ITSM) at 10 ms, enabling robust operation in HVDC valve stacks and traction rectifiers.
For engineers reviewing the T1930N38TOFVTXPSA1 datasheet, T1930N38TOFVTXPSA1 pinout, T1930N38TOFVTXPSA1 application, or T1930N38TOFVTXPSA1 equivalent, key selection criteria include junction-to-case thermal resistance (0.0078 °C/W two-sided), critical dv/dt rating (1000 V/µs), gate trigger current (≤300 mA), and latching current (≤1500 mA) under standardized test conditions.
Technical Context
This thyristor employs a pressure-contact silicon pellet structure with dual-side cooling capability and is optimized for forced-commutated or line-commutated turn-off in high-energy pulse applications. Its 450 µs typical circuit commutated turn-off time (tq) and 150 A/µs critical di/dt rating support reliable commutation in 50/60 Hz grid-connected systems with controlled firing angles.
The device features a defined on-state characteristic (vT = A + B·iT + C·ln(iT) + D·iT²) with Tvj max coefficients, enabling precise conduction loss modeling. Gate control uses flat and round terminal options per AMP 60598, supporting both low-inductance and standard mounting configurations in high-current busbar assemblies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDRM / VRRM | 3800 V - Maximum repetitive blocking voltage in forward/reverse direction, defining suitability for 3.3 kV AC line applications. |
| ITRMS | 4920 A - RMS on-state current capacity under sinusoidal conduction, directly determining thermal design margin for continuous load handling. |
| ITSM (10 ms) | 40000 A - Non-repetitive surge current rating, specifying short-circuit withstand capability during fault clearing. |
| (dv/dt)cr | 1000 V/µs - Minimum required snubber dv/dt immunity to prevent false triggering in high-di/dt environments. |
| RthJC (two-sided) | 0.0078 °C/W - Junction-to-case thermal resistance with dual-side cooling, setting baseline for heatsink sizing and thermal interface design. |
| IGT max | 300 mA - Maximum gate trigger current at 25°C and 12 V anode voltage, defining minimum driver output requirement. |
| tq typ | 450 µs - Typical commutated turn-off time at Tvj max, critical for calculating minimum commutation interval in phase-controlled rectifiers. |

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (1) | Main current terminal (high-side) | Carries full load current into device; requires low-inductance, high-force connection to busbar or heatsink. |

| Gate (4) | Control input | Triggers conduction; flat or round terminal per AMP 60598; must meet IGT ≤ 300 mA and VGT ≤ 3 V thresholds. |
| Auxiliary Cathode (5) | Secondary cathode reference | Provides low-impedance return path for gate drive and sensing; improves triggering reliability in stacked configurations. |
Key Features
| Feature | Design Value |
|---|---|
| Pressure-contact Si pellet | Enables scalable current handling up to 4920 A RMS without wire bonding limitations or thermal fatigue failure modes. |

| High (dv/dt)cr rating | 1000 V/µs ensures stable blocking during fast transients in high-voltage converter bridges without external snubbers. |
| Defined on-state V–I model | Four-coefficient analytical equation (A=2.085, B=7.262E−5, C=−0.244, D=0.02706) enables accurate loss simulation across 1–11 kA range. |
| Standardized gate terminals | Flat and round gate options (AMP 60598 compliant) support both low-inductance PCB-mounted drivers and rugged cable-based control wiring. |

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TT1930N38KOF | Same VDRM/VRRM (3800 V) and ITRMS (4920 A), but rated for 125°C Tvj max and uses TO-240AB package with different clamping geometry. | Designed for air-cooled stacks; lacks auxiliary cathode terminal; lower RthJC (0.0072 °C/W) but requires higher clamping force (55–105 kN). | Select when using forced-air heatsinks and requiring tighter thermal resistance, accepting revised mechanical mounting requirements. |

FAQ
What is the maximum allowable case temperature for continuous operation?
The maximum allowable case temperature (TC) depends on conduction angle and cooling method. With two-sided cooling and 180° sinusoidal conduction, TC must not exceed 85°C at 2180 A ITAV, or 55°C at 3140 A ITAV. Derating curves in the datasheet define exact limits for rectangular waveforms and partial conduction angles.
Does this thyristor require a heat sink, and what thermal interface materials are recommended?
Yes - mandatory use of a high-conductivity heatsink with dual-side contact is required due to its 4920 A ITRMS rating. Infineon specifies thermal grease with ≥8 W/m·K conductivity and surface roughness <0.8 µm Ra on both heatsink faces. Interface pressure must be maintained within 42–95 kN to ensure RthJC ≤ 0.0078 °C/W.
Can the auxiliary cathode terminal be left unconnected?
No - the auxiliary cathode (terminal 5) must be connected to the main cathode potential via low-inductance path. It provides critical gate return current routing and stabilizes triggering behavior in high-di/dt environments; leaving it floating risks erratic turn-on and increased gate power dissipation.
What gate drive voltage and current are required for reliable triggering?
A minimum gate pulse of 1.6 A peak current and 3 V amplitude is required at 25°C to guarantee turn-on within 3 µs. At Tvj max (125°C), gate trigger current increases to ≤300 mA, and gate non-trigger voltage drops to ≤0.25 V - drive circuits must comply with these limits across the full operating temperature range.
