Product details
Overview
TT250N16KOFHPSA1 from Infineon Technologies is a phase-control thyristor module designed for high-power AC line switching and rectification in industrial drive systems. It delivers 250 A average on-state current at TC = 85 °C, supports 1600 V repetitive peak off-state voltage (VDRM/VRRM), and features pressure-contact construction with electrically insulated baseplate for thermal and electrical isolation in crowbar and soft-starter applications.
For engineers reviewing the TT250N16KOFHPSA1 datasheet, TT250N16KOFHPSA1 pinout, TT250N16KOFHPSA1 application, or TT250N16KOFHPSA1 equivalent, key selection criteria include junction-to-case thermal resistance (0.124 K/W), critical dv/dt rating (1000 V/µs), gate trigger current (≤200 mA), and surge current capability (9100 A, 10 ms).
Technical Context
This dual-thyristor module operates in phase-controlled AC power regulation, where conduction angle determines output power. Its pressure-contact die attachment ensures low parasitic inductance and stable thermal performance under high di/dt (150 A/µs) and dv/dt (1000 V/µs) transients.
The module integrates two anti-parallel thyristor arms in a single industrial-standard package with basic insulation (IEC61140 Class 1) and pre-applied TIM option. It supports both DC and sinusoidal load currents up to 180° conduction, with validated turn-off time (tq = 250 µs) and holding current (IH ≤ 300 mA) for reliable commutation in static switches and UPS rectifiers.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDRM / VRRM | 1600 V - Maximum repetitive blocking voltage per arm; defines safe operating range in 400–690 V AC line applications. |
| ITAVM (TC = 85 °C) | 250 A - Continuous RMS current handling per arm; enables 410 A RMS operation with derating for thermal margin. |
| ITSM (10 ms) | 9100 A - Non-repetitive surge current; supports short-circuit protection in motor drives and crowbar circuits. |
| RthJC | 0.124 K/W - Junction-to-case thermal resistance per module; determines heatsink sizing for 125 °C max junction temperature. |
| (dv/dt)cr | 1000 V/µs - Critical rate of rise of off-state voltage; ensures immunity to false triggering in noisy industrial environments. |
| VTO / rT | 0.8 V / 0.7 mΩ - Threshold voltage and slope resistance; defines forward conduction loss profile at high current (e.g., 1.4 V @ 800 A). |
| tq | 250 µs - Circuit-commutated turn-off time; sets minimum commutation interval for forced-commutated converters. |
Pinout & Package
TT250N16KOFHPSA1 uses an industrial-standard press-pack module housing with electrically insulated baseplate (AlN ceramic). Terminal layout follows dual-arm configuration: main terminals T1/T2 for AC line connection and gate terminals G1/K1 and G2/K2 for independent arm control.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| T1 | Anode of Arm 1 | Main current path input for first thyristor arm; rated for full 250 A ITAVM and 9100 A ITSM. |
| T2 | Cathode of Arm 1 / Anode of Arm 2 | Common AC terminal; connects to load or bridge midpoint; electrically isolated from baseplate. |
| K2 | Cathode of Arm 2 | Main current path return for second thyristor arm; symmetric rating to T1. |
| G1, K1 | Gate & cathode of Arm 1 | Isolated gate drive interface; requires ≤2 V VGT and ≥1 A iGM for reliable latching (IL ≤ 1200 mA). |
| G2, K2 | Gate & cathode of Arm 2 | Independent gate control for anti-parallel operation; identical electrical specs to G1/K1. |
Key Features
| Feature | Design Value |
|---|---|
| Pressure contact die attachment | Eliminates wire bonds and solder fatigue; maintains stable RthJC and di/dt capability over >10⁵ thermal cycles. |
| Electrically insulated baseplate | AlN ceramic isolation (3.6 kV, 1 min) enables direct mounting to common heatsink without external insulators. |
| Pre-applied TIM option | Reduces RthCH by up to 25% (0.015 K/W vs. 0.02 K/W bare); simplifies thermal interface assembly and improves repeatability. |
| High dv/dt immunity | 1000 V/µs critical rating ensures robust operation in VFDs with fast-switching IGBT inverters nearby. |
| Low conduction loss | 0.8 V VTO + 0.7 mΩ rT yields <1.4 V drop at 800 A; minimizes PTAV and heatsink requirements in high-current rectifiers. |

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 |
|---|---|---|---|
| TT250N16KOFHPSA2 | Same die and package; differs only in TIM application status (pre-applied vs. not pre-applied). | No functional difference; PSA2 lacks factory-applied TIM, requiring manual TIM dispensing during assembly. | Select PSA1 when thermal interface consistency and reduced assembly steps are prioritized. |
| TD250N16KOFHPSA1 | Single-arm variant (vs. dual-arm TT); identical VDRM, ITAVM, and RthJC but half the conduction paths. | Requires two modules for anti-parallel operation; increases footprint and gate drive complexity vs. integrated dual-arm TT. | Choose TD only when asymmetric or unidirectional control is needed, or when redundancy mandates separate arms. |
Compared with TT250N16KOFHPSA1, PSA2 offers identical electrical performance but demands manual TIM application, while TD250N16KOFHPSA1 provides modularity at the cost of doubled gate drive channels and board area-making TT250N16KOFHPSA1 optimal for compact, high-integration soft starters and rectifiers.

FAQ
What is the maximum allowable junction temperature for TT250N16KOFHPSA1?
The maximum junction temperature (Tvj max) is 125 °C, as specified in the Infineon technical information document revision 3.6. This limit applies under all operating conditions including repetitive and non-repetitive surge events. Thermal design must ensure that transient and steady-state junction temperatures remain below this value using the provided ZthJC transient impedance data and RthJC = 0.124 K/W DC value.
Does TT250N16KOFHPSA1 require forced cooling?
Forced cooling is not mandatory but strongly recommended above ~150 A ITAVM depending on ambient and heatsink conditions. At 250 A ITAVM and 85 °C case temperature, the module dissipates ~350 W per arm. With RthCA = 0.2 K/W (typical forced-air heatsink), case-to-ambient rise would be ~70 K-exceeding safe limits without active airflow or liquid cooling.
Can TT250N16KOFHPSA1 be used in parallel configurations?
No-this module is not designed for parallel operation. Its pressure-contact architecture and lack of dynamic current-sharing features (e.g., matched VTO, integrated balancing resistors) make paralleling unreliable. For higher current, Infineon recommends using larger-rated modules (e.g., TT400N series) or multi-module systems with external current-sharing networks.
What gate drive voltage and current are required to reliably trigger TT250N16KOFHPSA1?
A minimum gate trigger voltage of 2 V (VGT max) and current of 1 A (iGM) are required for latching, with pulse width ≥20 µs. Gate non-trigger voltage (VGD max) is 0.2 V, so noise immunity requires clean, isolated gate drivers with <0.2 V offset. Recommended gate power is ≤100 W for 0.5 ms pulses, per the PGM vs. tg curve in the datasheet.
