Product details
Overview
TD190N16SOFHPSA2 from Infineon Technologies is a phase-control thyristor module with dual-arm configuration, rated for 1600 V repetitive peak off-state voltage (VDRM/VRRM), 190 A average on-state current at TC = 85 °C (ITAVM), and 5200 A non-repetitive surge current (ITSM). It features electrically insulated Al₂O₃ baseplate, solder-bond construction, and is designed for high-power AC line control in industrial rectifier and soft starter systems.
For engineers reviewing the TD190N16SOFHPSA2 datasheet, TD190N16SOFHPSA2 pinout, TD190N16SOFHPSA2 application, or TD190N16SOFHPSA2 equivalent, key selection criteria include junction-to-case thermal resistance (0.145 K/W per module), critical dv/dt rating (1000 V/µs), gate trigger current (≤145 mA), and isolation test voltage (3.6 kV for 1 sec).
Technical Context
This dual-thyristor module operates in phase-controlled AC power circuits, where precise gate triggering synchronizes conduction angle with AC line zero-crossing to regulate RMS output voltage and current. Its 125 °C maximum junction temperature and 0.9 mΩ slope resistance support high-efficiency operation under sustained 190 A DC-equivalent load conditions.
The module integrates two inverse-parallel thyristor chips in an industrial-standard package with electrically isolated baseplate, enabling direct mounting to heatsinks without additional insulation. Gate drive requirements are defined by VGT ≤ 2.5 V and IGT ≤ 145 mA at 25 °C, with critical di/dt capability of 100 A/µs and dv/dt immunity up to 1000 V/µs.

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 |
|---|---|---|---|
| TT190N16SOF | Same die, identical electrical specs, but non-isolated copper baseplate (no Al₂O₃ insulation) | Requires external insulating hardware; unsuitable for direct-mount heatsink designs requiring reinforced isolation | Select when cost-sensitive and isolation is provided externally; verify creepage/clearance compliance per IEC 61800-5-1 |
| TD190N16KO | Same voltage/current ratings, but uses older bond-wire interconnect (not solder-bond) and higher RthJC (0.17 K/W) | Lower thermal performance and reduced di/dt ruggedness; not recommended for high-dI/dt motor drives | Acceptable for lower-stress rectifier use; avoid in soft starters with high inrush ratios or frequent cycling |
Compared with TT190N16SOF and TD190N16KO, TD190N16SOFHPSA2 delivers superior thermal management (0.145 K/W), intrinsic isolation (3.6 kV), and solder-bond reliability-making it optimal for safety-critical, high-cycle industrial AC power control where board-level insulation and long-term thermal stability are mandatory.

FAQ
What is the maximum allowable case temperature for continuous operation?
The maximum case temperature (TC) for continuous operation is 85 °C, as specified by the ITAVM = 190 A rating. Operation above this temperature reduces permissible current linearly per the derating curve in the datasheet; exceeding 125 °C junction temperature (Tvj max) risks irreversible device failure.
Does TD190N16SOFHPSA2 require external snubber circuits?
Snubbers are not required for typical phase-control operation due to its 1000 V/µs (dv/dt)cr rating and 100 A/µs (di/dt)cr capability. However, snubbers are recommended in highly inductive loads (>10 mH) or when operating near VDRM limits to suppress voltage overshoot during commutation.
How is gate drive isolation implemented in this module?
Gate drive isolation is achieved via physically separated control terminals (G1/K1G and G2/K2G) with internal galvanic separation from main terminals. The module itself provides no integrated gate driver; external isolated gate drivers (e.g., Infineon 1ED020I12FA) must be used to meet IEC 61800-5-1 reinforced insulation requirements.
Can TD190N16SOFHPSA2 be used in parallel configurations?
Parallel operation is not recommended. The module is designed as a self-contained dual-arm unit; paralleling multiple modules introduces imbalance risks due to parameter spread (e.g., VTO, rT) and thermal coupling issues. For higher current, select a higher-rated single module (e.g., TD250N16SOFHPSA2) instead.
