Product details
Overview
T2001N34TOFXPSA1 from Infineon Technologies is a high-power phase-control thyristor designed for medium-voltage drive rectification and load-commutated inverter applications. It delivers 2060 A average on-state current at 85°C case temperature, 3400 V repetitive peak off-state voltage (VDRM/VRRM), and withstands 44 kA surge current (ITSM) with 300 A/µs critical di/dt capability.
For engineers reviewing the T2001N34TOFXPSA1 datasheet, T2001N34TOFXPSA1 pinout, T2001N34TOFXPSA1 application, or T2001N34TOFXPSA1 equivalent, key selection criteria include clamping force range (36–52 kN), two-sided thermal resistance (8.0 K/kW), gate trigger current ≤350 mA, and transient recovery charge ≤8.5 mAs under rated commutation conditions.
Technical Context
This thyristor employs a pressure-contact silicon pellet structure enabling bidirectional heat dissipation and high case non-rupture current. Its blocking capability is validated across –40°C to +125°C junction temperature with stable 3400 V DC and 50/60 Hz AC off-state voltage hold-off.
The device supports high di/dt turn-on (300 A/µs) and dv/dt immunity (1000 V/µs), with analytical transient thermal impedance data provided for anode-, cathode-, and two-sided cooling configurations to support precise thermal design in high-current converters.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDRM / VRRM | 3400 V - guarantees reliable 50/60 Hz and DC blocking up to medium-voltage AC line levels |
| ITAVM (TC = 85°C) | 2060 A - defines continuous conduction rating for rectifier stacks in industrial drives |
| ITSM (10 ms, Tvj = 25°C) | 44000 A - determines short-circuit robustness during fault events in cycloconverters |
| (diT/dt)cr | 300 A/µs - enables fast, controlled turn-on without spurious triggering in high-di/dt inverters |
| RthJC (two-sided) | 8.0 K/kW - sets minimum heatsink thermal conductance required for 85°C case operation |
| Qr (recovered charge) | 8.5 mAs - directly impacts snubber sizing and commutation circuit losses in LCIs |
| Clamping Force | 36–52 kN - specifies mechanical assembly torque range to maintain low contact resistance and thermal interface integrity |
Pinout & Package
Package: Press-pack, double-sided cooled, 121 mm diameter disc housing with integrated gate and auxiliary cathode terminals.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (1) | Main power terminal (high-side current path) | Carries full load current; requires symmetric clamping for thermal uniformity |
| Cathode (2) | Main power terminal (low-side current path) | Provides return path; thermally coupled to heatsink via direct metal contact |
| Gate (4) | Control input for turn-on initiation | Accepts ≤350 mA trigger pulse; isolated from main terminals per IEC 60747-6 |
| Auxiliary Cathode (5) | Secondary cathode connection for gate control reference | Ensures stable gate-cathode voltage reference under high dV/dt transients |
Key Features

| High case non-rupture current | Withstands mechanical stress from 44 kA surge without housing fracture or contact separation |
| Low threshold voltage (vT0 = 1.0 V) | Reduces conduction loss by ~15% vs. comparable 3.3 kV thyristors at 2000 A |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-power phase-control thyristor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TT1700N34KOF | Higher ITAVM (2150 A @ 85°C), identical VDRM/VRRM (3400 V), RthJC = 7.5 K/kW | Better suited for continuous-duty rectifiers requiring margin above 2060 A | Select when thermal headroom or long-term derating is critical |
| T2001N32TOFXPSA1 | Lower VDRM/VRRM (3200 V), same ITAVM (2060 A), identical package and clamping specs | Used where system overvoltage protection limits maximum blocking requirement | Select when 3200 V rating satisfies insulation coordination and reduces cost |
Compared with TT1700N34KOF and T2001N32TOFXPSA1, the T2001N34TOFXPSA1 offers optimal balance of 3400 V blocking, 2060 A conduction, and 8.0 K/kW thermal resistance-making it ideal for medium-voltage drives where both voltage margin and thermal efficiency are constrained.

FAQ
What is the recommended clamping force range for T2001N34TOFXPSA1?
The specified clamping force is 36–52 kN. Applying force within this range ensures optimal thermal contact resistance between the silicon pellet and copper electrodes, maintains mechanical stability under 44 kA surge currents, and prevents micro-movement that could degrade long-term conduction performance. Exceeding 52 kN risks deformation of internal contacts.
Does T2001N34TOFXPSA1 require forced gate triggering?
Yes-it is a gate-controlled thyristor requiring a defined gate trigger pulse (≤350 mA, ≤2.5 V) to initiate conduction. Unlike DIAC-triggered devices, it does not self-fire; precise timing control is achieved via external gate drivers synchronized to AC line zero-crossing for phase-angle modulation.
Can T2001N34TOFXPSA1 be used in single-sided cooled configurations?
Yes, but with derating: RthJC increases to 15.0 K/kW (anode-cooled) or 17.0 K/kW (cathode-cooled). This raises junction temperature by ~35°C at 2060 A, requiring either reduced current rating or enhanced heatsink performance. Two-sided cooling is strongly preferred for rated operation.
What is the significance of the 'O' 4th letter in the type designation?
The 'O' denotes a circuit-commutated turn-off time (tq) of 300 µs (typical) at maximum junction temperature and rated current. This parameter defines the minimum time required for natural current zero-crossing and reverse recovery before safe reapplication of forward voltage-critical for reliable operation in load-commutated inverters and cycloconverters.
