Product details

Overview

T2001N36TOFXPSA1 from Infineon Technologies is a phase-control thyristor designed for high-power medium-voltage AC/DC conversion, featuring V_DRM/V_RRM = 3600 V, I_TAVM = 2060 A at T_C = 85°C, and I_TSM = 44 kA (10 ms), used in load-commutated inverters and industrial drive rectifiers.

For engineers reviewing the T2001N36TOFXPSA1 datasheet, T2001N36TOFXPSA1 pinout, T2001N36TOFXPSA1 application, or T2001N36TOFXPSA1 equivalent, key selection criteria include blocking voltage stability at 125°C junction, di/dt capability of 300 A/µs, gate trigger current ≤350 mA, and two-sided forced cooling compatibility with 36–52 kN clamping force.

Technical Context

This thyristor employs a pressure-contact silicon pellet structure enabling bidirectional heat extraction and stable conduction under 50/60 Hz line-frequency blocking. Its critical dv/dt rating of 1000 V/µs and di/dt rating of 300 A/µs support reliable turn-on in high-di/dt commutation circuits without snubbers.

Thermal design relies on transient junction-to-case impedance modeling (Z_thJC) with analytical R-τ network parameters for both anode- and cathode-sided cooling configurations. The device operates up to 125°C junction temperature with 8.0 K/kW maximum steady-state R_thJC under two-sided DC cooling.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DRM/V_RRM	3600 V - Sustains full 50/60 Hz AC line voltage in medium-voltage drives up to 3.6 kV system level.
I_TAVM	2060 A @ T_C = 85°C - Continuous RMS conduction current rating for rectifier stacks in industrial motor drives.
I_TSM	44000 A @ 10 ms - Withstands short-circuit surge currents in cycloconverter and LCI fault conditions.
(di/dt)_cr	300 A/µs - Enables direct triggering without external di/dt limiting in fast-switching phase-control topologies.
(dv/dt)_cr	1000 V/µs - Maintains off-state integrity during rapid voltage transients in unfiltered AC line interfaces.
R_thJC	8.0 K/kW (two-sided DC) - Defines minimum heatsink thermal resistance required to maintain T_vj ≤ 125°C at full load.
v_T0, r_T	1.0 V, 0.25 mΩ - Low conduction loss profile supporting <1.5 V forward drop at 2000 A, reducing thermal stress in high-current paths.

Pinout & Package

Package: Disc-type, double-side cooled, press-pack thyristor with 121 mm max diameter, 86 mm contact diameter, and 26 mm height. Requires mechanical clamping force of 36–52 kN.

Pin/Terminal	Circuit Role	Design Meaning
Anode (1)	Main power terminal (high-side current path)	Carries full load current into device; must be mounted to heatsink with uniform pressure distribution.
Cathode (2)	Main power terminal (low-side current path)	Completes main conduction loop; electrically isolated mounting surface required for dual-sided cooling.
Gate (4)	Control input	Triggers conduction when ≥350 mA pulse applied; sensitive to noise-requires shielded gate wiring.
Hilfskathode / Auxiliary Cathode (5)	Gate return reference	Provides low-inductance gate current return path independent of main cathode; essential for stable triggering.

Key Features

Feature	Design Value
Full 50/60 Hz blocking over -40°C to +125°C	Ensures uninterrupted operation across industrial ambient and junction temperature extremes without derating.
High case non-rupture current	Withstands 44 kA surge without mechanical failure-critical for fault-tolerant drive systems.
Two-sided DC cooling interface	Enables 8.0 K/kW R_thJC, halving thermal resistance versus single-sided mounting for same footprint.
Pressure-contact Si pellet construction	Eliminates solder fatigue and thermal cycling failure modes common in metallized-base packages.
300 A/µs critical di/dt	Supports direct gate triggering in high-speed phase control without series inductors or snubber networks.

Applications

High-Current Rectifier

Rectifier for Drives Applications

Use Scenario: 3-phase, 6-pulse rectification in >5 MW steel mill rolling drives operating at 2.5–3.3 kV AC line voltage.

IC Role / Device Role / Timing Role: Main power switching element in series-connected thyristor stacks, triggered synchronously with AC zero-crossing.

Use Value: 3600 V blocking and 2060 A average current enable compact stack design with reduced parallel devices and lower conduction losses.

Use Scenario: Field-weakening rectifier stage in high-inertia HVAC compressors requiring regenerative braking via controlled conduction angle.

IC Role / Device Role / Timing Role: Phase-controlled conduction element modulating DC bus voltage by adjusting firing delay relative to AC phase.

Use Value: 300 A/µs di/dt capability ensures precise turn-on timing even under rapidly changing load inductance, minimizing torque ripple.

Medium Voltage Drives

Load Commutating Inverter (LCI)

Use Scenario: Input rectifier section of 4.16 kV MV drive feeding synchronous motors in mining conveyor systems.

IC Role / Device Role / Timing Role: Line-commutated switch converting utility AC to regulated DC, coordinated with inverter thyristors for harmonic mitigation.

Use Value: 1000 V/µs dv/dt rating prevents false triggering during high-dv/dt transients from upstream transformer switching.

Use Scenario: Inverter bridge in large synchronous motor drives where load inductance provides natural commutation.

IC Role / Device Role / Timing Role: Bidirectional current-handling switch turned off by reverse voltage from rotating load back-EMF.

Use Value: 300 µs typical turn-off time (t_q) and 8.5 mAs recovered charge ensure reliable commutation margin at 50 Hz fundamental frequency.

Equivalent & Alternatives

The following parts are listed as comparable options for similar phase-control thyristor applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
TT2000N36KOF	V_DRM/V_RRM = 3600 V, I_TAVM = 2000 A @ 85°C, R_thJC = 8.5 K/kW, no auxiliary cathode terminal	Lacks dedicated gate return path; requires careful PCB layout to minimize gate loop inductance	Preferred where gate drive simplicity outweighs need for ultra-stable triggering in noisy EMI environments
SKKT 2000/36	V_DRM/V_RRM = 3600 V, I_TAVM = 2050 A @ 85°C, R_thJC = 9.2 K/kW, integrated heat sink interface	Uses bolt-down package instead of press-pack; lower clamping force requirement (25–40 kN)	Selected when mechanical assembly constraints prohibit high-force press-fit mounting

Compared with TT2000N36KOF and SKKT 2000/36, T2001N36TOFXPSA1 offers superior gate noise immunity via auxiliary cathode, tighter thermal resistance (8.0 vs. ≥8.5 K/kW), and higher surge current margin (44 vs. 42 kA), making it optimal for mission-critical LCI and high-reliability drive rectifiers.

FAQ

What is the recommended clamping force range for T2001N36TOFXPSA1?

The device requires a mechanical clamping force between 36 kN and 52 kN to ensure uniform pressure across the 86 mm contact diameter and maintain specified R_thJC and v_T performance. Force below 36 kN increases contact resistance and thermal impedance; above 52 kN risks ceramic housing fracture or silicon pellet damage.

Does T2001N36TOFXPSA1 support single-sided cooling?

Yes, but with significant thermal penalty: R_thJC degrades to 15.0 K/kW (anode-cooled) or 17.0 K/kW (cathode-cooled), reducing maximum allowable I_TAVM by ~30% at T_C = 85°C. Two-sided cooling is strongly recommended to achieve rated 2060 A conduction.

What gate drive parameters ensure reliable triggering?

A minimum gate trigger current of 350 mA (peak), 2.5 V gate voltage, and ≥3 A latching current with di/dt ≥6 A/µs are required. Gate pulse width must exceed 20 µs, and the auxiliary cathode (terminal 5) must be connected directly to gate driver ground to minimize loop inductance and prevent misfiring.

How does the auxiliary cathode (terminal 5) differ from the main cathode (terminal 2)?

Terminal 5 is a dedicated low-inductance return path for gate current only-it is not rated for main conduction current. It electrically isolates gate drive return from high-di/dt main cathode current paths, preventing gate signal corruption during turn-on and improving noise immunity in high-power EMI environments.
