Product details
Overview
TD190N18SOFHPSA1 from Infineon Technologies is a phase-control thyristor module designed for high-power AC line switching and rectification in industrial power electronics. It delivers 190 A average on-state current (ITAVM) at TC = 85 °C, 1800 V repetitive peak off-state voltage (VDRM/VRRM), and 5200 A non-repetitive surge current (ITSM), with electrically insulated baseplate and solder-bond construction. It is used in soft starters for three-phase induction motors.
For engineers reviewing the TD190N18SOFHPSA1 datasheet, TD190N18SOFHPSA1 pinout, TD190N18SOFHPSA1 application, or TD190N18SOFHPSA1 equivalent, key selection criteria include junction-to-case thermal resistance (0.145 K/W), critical dv/dt rating (1000 V/µs), gate trigger current (≤145 mA), and RMS on-state current capability (275 A).
Technical Context
This dual-thyristor module operates in phase-controlled AC applications where precise conduction-angle modulation regulates power delivery. Its 125 °C maximum junction temperature, 0.9 mΩ slope resistance, and 0.85 V threshold voltage define its conduction efficiency under high-current DC-link or motor-drive conditions.
The module features electrically isolated Al₂O₃ ceramic baseplate, 3.0 kV RMS insulation test voltage (1 min), and mechanical mounting torque specifications (5 Nm for M1/M2 terminals). Its transient thermal impedance ZthJC is characterized for both sinusoidal and rectangular current waveforms across conduction angles from 30° to 180°.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDRM / VRRM | 1800 V - Maximum repetitive blocking voltage per thyristor arm; defines safe operation in 1.1 kV AC line systems with margin. |
| ITAVM (TC = 85 °C) | 190 A - Continuous average forward current per arm at heatsink temperature; sets thermal design baseline for forced-air or liquid cooling. |
| ITSM (10 ms) | 5200 A - Non-repetitive surge current capability; supports short-circuit withstand in motor starter fault clearing. |
| RthJC | 0.145 K/W - Junction-to-case thermal resistance per module; determines minimum heatsink thermal resistance required for 125 °C Tj max. |
| (dvD/dt)cr | 1000 V/µs - Critical rate of rise of off-state voltage; ensures reliable blocking during fast transients without spurious turn-on. |
| VT0 / rT | 0.85 V / 0.9 mΩ - Threshold voltage and slope resistance; defines forward conduction loss profile up to 500 A peak current. |
| IGT max | 145 mA - Maximum gate trigger current at 25 °C and 12 V anode-cathode voltage; informs gate driver output current requirement. |
Pinout & Package
TD190N18SOFHPSA1 is housed in an industrial-standard press-pack thyristor module package with electrically insulated Al₂O₃ baseplate, 34 mm baseplate height, and 165 g mass. Terminal layout follows dual-arm configuration with isolated gate control inputs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A1 / K2 | Anode 1 / Cathode 2 | Main current terminals for first thyristor arm; configured for anti-parallel or bridge-leg use in B2/B6 rectifiers. |
| K1 / A2 | Cathode 1 / Anode 2 | Main current terminals for second thyristor arm; enables full-wave phase-controlled rectification or AC static switching. |
| G1 / G2 | Gate 1 / Gate 2 | Isolated low-energy gate drive inputs; require ≤145 mA trigger current and ≤2.5 V trigger voltage for reliable turn-on. |
| Baseplate | Electrically insulated case | Al₂O₃-ceramic insulated mounting surface rated for 3.0 kV RMS isolation; enables direct heatsink mounting without additional insulator. |
Key Features
| Feature | Design Value |
|---|---|
| Solder-bond interconnect | Eliminates wire bonds and reduces parasitic inductance, improving di/dt robustness and thermal cycling reliability. |
| Electrically insulated baseplate | Al₂O₃ ceramic substrate provides 3.0 kV RMS isolation, enabling direct mounting to grounded heatsinks in high-voltage systems. |
| High dv/dt immunity | 1000 V/µs critical off-state voltage rise rate prevents false triggering in noisy industrial environments with fast-switching loads. |
| Low conduction losses | 0.85 V VT0 and 0.9 mΩ rT yield <1.52 V on-state drop at 500 A, reducing thermal load in continuous-duty rectifier applications. |
| Rated for 125 °C junction | Enables operation in high-ambient industrial enclosures without derating when paired with appropriate heatsinking (RthCA ≤ 0.2 K/W). |

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 |
|---|---|---|---|
| TT190N18SOF | Same die, identical electrical specs, but non-insulated baseplate (no Al₂O₃ isolation); RthJC = 0.0725 K/W (per arm, DC). | Requires external isolation kit for grounded heatsink mounting; unsuitable where creepage/clearance or safety certification mandates internal insulation. | Select TT190N18SOF only when baseplate isolation is unnecessary and lower thermal resistance is prioritized over safety compliance. |
| TD162N16KOF | Lower voltage rating (1600 V VDRM), lower current (162 A ITAVM), same package footprint and insulated baseplate. | Limited to 400–480 V AC systems; insufficient for 690 V line applications or higher surge demands beyond 4500 A ITSM. | Choose TD162N16KOF for cost-sensitive 400 V soft starters where 1800 V margin is not required. |
Compared with TT190N18SOF and TD162N16KOF, TD190N18SOFHPSA1 uniquely combines 1800 V blocking, 190 A thermal rating, and certified internal insulation-making it the only option qualified for safety-critical 690 V industrial rectifiers requiring reinforced insulation without external barriers.

FAQ
What is the maximum allowable case temperature for continuous operation?
The maximum allowable case temperature (TC) is +125 °C, aligned with the 125 °C maximum junction temperature (Tvj max) and 0.145 K/W junction-to-case thermal resistance. Operation above this temperature risks irreversible degradation of the solder-bond interconnect and Al₂O₃ insulation integrity.
Does TD190N18SOFHPSA1 require snubber circuits in standard 50/60 Hz applications?
Snubbers are recommended for applications exceeding 1000 V/µs dv/dt or involving highly inductive loads, despite the device's rated (dvD/dt)cr of 1000 V/µs. For 690 V AC line rectifiers with typical line reactors, RC snubbers across each thyristor arm improve reliability during commutation and fault recovery.
Can this module be used in anti-parallel configuration for AC static switching?
Yes - the dual-thyristor architecture supports anti-parallel connection per phase, enabling bidirectional AC line control. Gate signals must be isolated and timed to avoid shoot-through; the 2 µs maximum gate delay (tgd) and 100 A/µs (diT/dt)cr ensure precise synchronization in static switch topologies.
What is the creepage distance and why does it matter for PCB layout?
The creepage distance is 10 mm, measured across the insulated baseplate surface between main terminals. This value satisfies IEC 61800-5-1 requirements for Pollution Degree 3 environments and dictates minimum spacing between high-voltage traces and grounded planes in associated gate driver or heatsink-mounting layouts.
