Product details
Overview
T1930N36TOFVTXPSA1 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 3600 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, with a critical dv/dt rating of 1000 V/µs and junction temperature up to 125 °C - deployed in HVDC converter valves and traction rectifiers.
For engineers reviewing the T1930N36TOFVTXPSA1 datasheet, T1930N36TOFVTXPSA1 pinout, T1930N36TOFVTXPSA1 application, or T1930N36TOFVTXPSA1 equivalent, key selection criteria include verified gate trigger current (≤300 mA), clamping force range (42–95 kN), two-sided thermal resistance (0.0078 °C/W), auxiliary cathode terminal configuration, and transient thermal impedance profile for 180° conduction-angle operation.
Technical Context
This thyristor operates as a line-commutated, gate-controlled switch in phase-angle controlled rectification circuits. Its design supports forced commutation via external circuit reversal and requires precise gate pulse timing (tgd ≤ 3 µs) and robust dv/dt immunity (1000 V/µs) to prevent false turn-on during voltage transients.
It features a silicon pellet with pressure-contact construction, dual cooling interfaces (anode and cathode), and an auxiliary cathode terminal for improved current sharing in series-connected stacks. Thermal performance is defined by analytical ZthJC models for sinusoidal and rectangular currents across conduction angles from 30° to 180°.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDRM / VRRM | 3600 V - maximum repetitive blocking voltage in forward/reverse direction, enabling use in 3.3 kV-class AC systems |

| ITAVM @ TC = 85°C | 2180 A - average on-state current limit at case temperature 85 °C, defining continuous DC load capability |
| ITSM (10 ms) | 40000 A - non-repetitive surge current withstand, critical for short-circuit protection coordination |
| (dvD/dt)cr | 1000 V/µs - minimum critical rate-of-rise of off-state voltage before spurious turn-on occurs |
| RthJC (two-sided) | 0.0078 °C/W - junction-to-case thermal resistance with bidirectional heatsinking, enabling high-power dissipation |

Equivalent & Alternatives
The following parts are listed as comparable options for similar phase-control thyristor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| T1930N36TOFVTXPSA2 | Same die, higher clamping force spec (50–100 kN); identical VDRM, ITRMS, and thermal specs | Designed for enhanced mechanical reliability in vibration-prone traction applications | Select when specifying for rail or marine environments requiring extended mechanical qualification |
| TT1930N36KOF | Same voltage/current ratings but TO-240AB package with isolated base; no auxiliary cathode terminal | Lacks auxiliary cathode, limiting use in series-stacked valve designs requiring dynamic current balancing | Choose only for single-device or parallel-only configurations where auxiliary cathode is not needed |
Compared with T1930N36TOFVTXPSA2 and TT1930N36KOF, the T1930N36TOFVTXPSA1 uniquely combines auxiliary cathode functionality, 42–95 kN clamping range, and validated ZthJC modeling - making it the preferred choice for series-connected HVDC valve stacks requiring synchronized firing and thermal predictability.

FAQ
What is the recommended gate drive circuit for T1930N36TOFVTXPSA1?
The gate drive must deliver ≥1.6 A peak current with diG/dt ≥1.6 A/µs and pulse width ≥20 µs to ensure reliable latching. A 300 mA maximum trigger current (IGT) and 3 V maximum gate voltage (VGT) require isolation-rated drivers with tight timing control. Gate resistor selection must limit peak power to ≤60 W for 0.5 ms pulses per the PGM curve.
Can T1930N36TOFVTXPSA1 be used in series-string configurations?
Yes - its auxiliary cathode terminal (pin 5) is explicitly designed for dynamic current balancing in series strings. Matching dv/dt ratings (1000 V/µs), gate propagation delay (≤3 µs), and thermal time constants across units is mandatory, and active voltage-sharing networks are recommended for >4-device stacks.
What thermal interface material is specified for two-sided cooling?
Infineon specifies thermally conductive, electrically insulating grease or phase-change pads compliant with UL 94 V-0, applied uniformly under 42–95 kN clamping force. Surface roughness must be ≤1.6 µm Ra on both anode and cathode mounting surfaces to ensure uniform pressure distribution and minimal interfacial thermal resistance.
Is T1930N36TOFVTXPSA1 qualified for automotive traction applications?
No - while widely used in rail traction rectifiers, this device carries no AEC-Q101 qualification. Its preliminary data sheet (2008) and thermal/mechanical specs align with industrial and energy infrastructure standards (IEC 60747-6), not automotive functional safety or environmental stress requirements.
