Product details
Overview
TD250N16KOFTIMHPSA1 from Infineon Technologies is a phase-control thyristor module designed for high-power AC line switching in industrial power converters. It delivers 250 A average on-state current (TC = 85 °C), 1600 V repetitive peak off-state voltage (VDRM/VRRM), and 9100 A non-repetitive surge current (ITSM), with electrically insulated baseplate and pre-applied thermal interface material (TIM). It is used in soft starters, static switches, and battery charger rectifiers.
For engineers reviewing the TD250N16KOFTIMHPSA1 datasheet, TD250N16KOFTIMHPSA1 pinout, TD250N16KOFTIMHPSA1 application, or TD250N16KOFTIMHPSA1 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 pressure-contact construction for high-cycle reliability under repetitive surge stress.
Technical Context
This dual-thyristor, press-pack module operates in phase-controlled AC applications where precise conduction-angle regulation enables smooth voltage/current ramping. Its 125 °C maximum junction temperature, 0.7 mΩ slope resistance, and 250 µs circuit-commutated turn-off time support stable operation in 50/60 Hz drive rectifiers and crowbar protection circuits.
The module integrates two anti-parallel thyristor chips per arm in an industrial-standard package with AlN ceramic isolation and M1/M2 screw terminals. Pre-applied TIM reduces thermal interface resistance to ≤0.015 K/W (per module), enabling efficient heat transfer to heatsinks in high-power UPS and motor control systems.
Key Specifications

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 |
|---|---|---|---|
| TT250N16KOF | No pre-applied TIM; RthCH = 0.02 K/W (vs. 0.015 K/W with TIM); identical electrical ratings and package. | Requires user-applied thermal paste or pad; suitable where TIM rework or custom interface materials are preferred. | Select TT250N16KOF if thermal interface process control or TIM replacement is required during field service. |
| TD250N12KOFTIMHPSA1 | Lower VDRM/VRRM (1200 V); same ITAVM, ITSM, RthJC, and TIM configuration. | Limited to 230–400 V AC systems; not suitable for 690 V industrial drives or UPS with higher line voltage margins. | Choose TD250N12KOFTIMHPSA1 only for cost-sensitive 400 V-class applications where 1600 V margin is unnecessary. |
Compared with TT250N16KOF, TD250N16KOFTIMHPSA1 reduces thermal interface assembly time and improves thermal repeatability; versus TD250N12KOFTIMHPSA1, it provides essential 1600 V blocking headroom for 690 V AC systems and transient overvoltage resilience.

FAQ
What is the maximum allowable case temperature for continuous operation?
The maximum case temperature (TC) for continuous operation is +125 °C, as specified in the thermal characteristics table. At this temperature, the device supports 250 A ITAVM with appropriate heatsinking and airflow. Derating curves in the datasheet show that ITAVM drops to ~200 A at TC = 100 °C for 180° conduction angle.
Can TD250N16KOFTIMHPSA1 be used in parallel configurations?
No-this module is not designed for paralleling. Its pressure-contact architecture and lack of integrated current-sharing features (e.g., matched VTO, dynamic balancing networks) make parallel operation unreliable. For higher current, use multi-module systems with external forced-current sharing or select higher-rated single modules like TD330N16KOFTIMHPSA1.
What gate drive voltage and current are required for reliable triggering?
A minimum gate trigger voltage of 2 V and current of 200 mA (at 25 °C, vD = 12 V) ensures turn-on under worst-case conditions. The gate characteristic curve shows usable triggering down to 1 V/100 mA at Tvj = –40 °C, but designs should target ≥3 V/300 mA pulses (≤20 µs width) for margin against aging and temperature drift.
Is the baseplate electrically isolated, and what is its isolation rating?
Yes-the baseplate uses aluminum nitride (AlN) ceramic insulation rated for 3.0 kV RMS (1 minute, 50 Hz) and 3.6 kV RMS (1 second), meeting IEC61140 Class I safety requirements. This allows direct mounting to grounded heatsinks without additional insulators, simplifying mechanical design and improving thermal performance.
