Product details
Overview
TT240N32KOFHPSA1 from Infineon Technologies is a phase-control thyristor module rated for 3200 V repetitive peak off-state voltage (VDRM/VRRM), 240 A average on-state current (ITAVM) at TC = 85°C, and 6100 A non-repetitive surge current (ITSM). It features dual thyristor arms in press-pack construction with AlN isolation, designed for high-power AC line commutated rectification in industrial motor drives and medium-voltage DC power supplies.
For engineers reviewing the TT240N32KOFHPSA1 datasheet, TT240N32KOFHPSA1 pinout, TT240N32KOFHPSA1 application, or TT240N32KOFHPSA1 equivalent, key selection criteria include its 0.039 °C/W junction-to-case thermal resistance per module, 100 A/µs critical di/dt rating, 500 V/µs critical dv/dt capability, and gate trigger parameters (IGT ≤ 250 mA, VGT ≤ 1.5 V) under standard test conditions.
Technical Context
This dual-arm thyristor module operates in natural- or forced-cooled configurations with sinusoidal or rectangular conduction angles (Θ = 30°–180°). Its design supports line-commutated turn-off (tq typ. 350 µs) and withstands 3.0 kV RMS insulation test voltage for 1 minute.
The module uses silicon pellets with pressure-contact metallization and aluminum nitride (AlN) internal isolation. Thermal performance is characterized by analytical ZthJC and ZthCA transient impedance models, enabling precise loss and temperature prediction across duty cycles and cooling conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDRM / VRRM | 3200 V - Maximum repetitive blocking voltage per arm, defining usable AC line voltage range up to 2200 V RMS. |
| ITAVM (TC = 85°C) | 240 A - Continuous average current per arm under heatsink-limited thermal conditions. |
| ITSM (10 ms) | 6100 A - Short-circuit withstand capability without latch-up or thermal runaway. |
| (diT/dt)cr | 100 A/µs - Minimum required snubber dI/dt rating to prevent false turn-on during commutation. |
| (dvD/dt)cr | 500 V/µs - Required snubber dv/dt rating to avoid spurious triggering under fast transients. |
| RthJC (per module) | 0.039 °C/W - Junction-to-case thermal resistance under DC conduction, critical for heatsink sizing. |
| vT max (iT = 1200 A) | 3.43 V - On-state voltage drop at high current, directly determining conduction losses (PTAV ≈ vT × ITAV). |
Pinout & Package
TT240N32KOFHPSA1 is a press-pack dual-thyristor module housed in an insulated metal case with two isolated power arms. Electrical terminals are M1 (mechanical mounting) and M2 (electrical connection) screw terminals per arm; control terminals conform to DIN 46244 A (2.8 × 0.8 mm flat blade).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode 1 (A1) | Main current terminal - Arm 1 anode | High-current input for first thyristor arm; requires ≥12 Nm torque on M2 terminal. |
| Cathode 1 (K1) | Main current terminal - Arm 1 cathode | High-current output for first arm; electrically isolated from Arm 2 via AlN substrate. |
| Gate 1 (G1) | Control input - Arm 1 gate | Low-energy trigger interface (≤250 mA, ≤1.5 V); must be isolated from other gates and power paths. |
| Anode 2 (A2) | Main current terminal - Arm 2 anode | Second independent thyristor arm anode; enables B2/B6 bridge topologies. |
| Cathode 2 (K2) | Main current terminal - Arm 2 cathode | Second arm cathode; shares case thermal path but maintains >19 mm creepage distance to A1/K1. |
| Gate 2 (G2) | Control input - Arm 2 gate | Independent gate drive node; no internal coupling to G1 - allows asymmetric firing control. |
Key Features
| Feature | Design Value |
|---|---|
| Press-pack Si pellet construction | Eliminates wire bonds and solder layers, enabling >125°C junction operation and >10⁶ thermal cycles. |
| AlN ceramic isolation | Provides 3.0 kV RMS insulation strength and stable thermal conductivity (170 W/m·K) over lifetime. |
| Dual independent thyristor arms | Supports B2 (2-pulse) and B6 (6-pulse) rectifier topologies without external isolation components. |
| Gate-trigger robustness | Guaranteed turn-on with IGT ≤ 250 mA and VGT ≤ 1.5 V at 25°C, with IH ≤ 300 mA holding current. |
| Transient thermal modeling | Supplied ZthJC and ZthCA analytical functions enable accurate loss and temperature simulation for arbitrary waveforms. |
Applications
| Industrial Motor Drives | Medium-Voltage DC Power Supplies |
|---|---|
|
Use Scenario: 3-phase, 6-pulse thyristor rectifier feeding DC link of 500 kW induction motor drive operating at 690 V AC line. IC Role / Device Role / Timing Role: Line-commutated power conversion stage; each TT240N32KOFHPSA1 arm handles one phase leg in B6 configuration. Use Value: Enables direct AC-to-DC conversion without intermediate transformers; 3200 V blocking supports 690 V AC systems with 2× safety margin. |
Use Scenario: High-reliability DC power supply for electroplating process requiring 1200 A @ 12 V DC output with adjustable voltage via phase-angle control. IC Role / Device Role / Timing Role: Main power switching element in single-phase or three-phase controlled rectifier; gate timing defines output voltage level. Use Value: 240 A average current rating per arm sustains full-load operation with natural cooling; low RthJC minimizes heatsink mass. |
| Static VAR Compensators (SVC) | DC Traction Substations |
|
Use Scenario: Thyristor-switched capacitor bank in utility-scale SVC system regulating reactive power on 33 kV distribution feeder. IC Role / Device Role / Timing Role: Fast-switching reactive power controller; synchronized firing controls capacitive current injection timing. Use Value: 100 A/µs di/dt rating ensures reliable turn-on under high dv/dt from capacitor switching transients. |
Use Scenario: Rectifier station converting 25 kV AC catenary supply to 1500 V DC for urban rail traction systems. IC Role / Device Role / Timing Role: Primary power conversion module in multi-pulse rectifier; configured as B12 using two modules per phase.

Equivalent & Alternatives
The following parts are listed as comparable options for similar phase-control thyristor module applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TT240N36KOFHPSA1 | Higher VDRM/VRRM (3600 V); identical ITAVM, RthJC, and gate specs. | Required where system peak line voltage exceeds 2500 V RMS (e.g., 36 kV feeders with overvoltage transients). | Select when higher blocking margin is needed without changing thermal or drive design. |
| TD240N32KOFHPSA1 | Single-arm version; same VDRM, ITAVM, and thermal specs but half the package size and weight. | Suitable for single-phase or asymmetrical rectifier designs where dual-arm integration is unnecessary. | Choose for cost-sensitive or space-constrained applications needing only one thyristor arm. |
Compared with TT240N32KOFHPSA1, the 3600 V variant offers extended voltage headroom at no thermal or drive penalty, while the TD240N32KOFHPSA1 reduces footprint and cost for single-arm use cases-neither is pin-compatible due to differing terminal count and isolation layout.

FAQ
What is the maximum allowable junction temperature for TT240N32KOFHPSA1?
The maximum junction temperature (Tvj max) is 125°C, as specified in the thermal properties section of the official datasheet. Operation beyond this limit risks irreversible degradation of the silicon die and AlN isolation layer. Derating curves in the datasheet define safe ITAVM limits versus case temperature and conduction angle.
Does TT240N32KOFHPSA1 require forced cooling?
No - it supports both natural (air) and forced (fan) cooling. At ITAVM = 240 A and Θ = 180°, natural cooling with KM17 heatsink yields TC ≈ 110°C; forced cooling lowers TC to ~85°C. The choice depends on system thermal budget and reliability targets - derating guidance is provided in pages 7–8 of the datasheet.
Can TT240N32KOFHPSA1 be used in reverse-conducting configurations?
No - it is a standard forward-conducting, reverse-blocking thyristor module. It lacks integrated reverse freewheeling diodes and cannot conduct current in reverse direction. For reverse-conducting operation, discrete anti-parallel diode pairing or dedicated RC-SCR modules are required.
What gate drive voltage and current are required to reliably trigger TT240N32KOFHPSA1?
A minimum gate trigger current of 250 mA and voltage of 1.5 V (at 25°C, vD = 6 V) guarantees turn-on. Recommended drive is ≥500 mA peak with 10–20 µs pulse width and <1 µs rise time. Gate non-trigger current remains ≤10 mA up to Tvj max, ensuring noise immunity in high-dv/dt environments.
