Product details
Overview
TD240N18SOFHPSA1 from Infineon Technologies is a phase-control thyristor module designed for high-power AC line switching and rectification in industrial power electronics. It delivers 240 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-used in soft starters and UPS rectifiers.
For engineers reviewing the TD240N18SOFHPSA1 datasheet, TD240N18SOFHPSA1 pinout, TD240N18SOFHPSA1 application, or TD240N18SOFHPSA1 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 enables adjustable power delivery. Its 140 °C maximum junction temperature, 0.9 mΩ slope resistance (rT), and 0.85 V threshold voltage (VT0) support stable conduction under high-current, high-temperature conditions typical of motor drives and battery chargers.
The module integrates two anti-parallel thyristor chips in an industrial-standard package with Al₂O₃-based electrical isolation and 3.0 kV RMS insulation test voltage. Its 370 µs turn-off time (tq) and 100 A/µs critical di/dt rating enable reliable commutation in B2 and B6 bridge configurations with sinusoidal or rectangular current waveforms.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDRM / VRRM | 1800 V - Maximum repetitive blocking voltage in forward and reverse directions, defining safe AC line voltage operation up to 1200 V RMS. |
| ITAVM | 240 A @ TC = 85 °C - Continuous average on-state current per arm, specifying thermal-limited DC or low-frequency AC load capacity. |
| ITSM | 5200 A @ tP = 10 ms - Non-repetitive surge current capability, determining short-circuit withstand in motor starting or fault conditions. |
| RthJC | 0.145 K/W - Junction-to-case thermal resistance per module (DC), directly governing heatsink sizing for sustained 240 A operation. |
| (dvD/dt)cr | 1000 V/µs - Critical rate of rise of off-state voltage, indicating immunity to false triggering from fast transients in noisy industrial environments. |
| VT0 / rT | 0.85 V / 0.9 mΩ - Threshold voltage and slope resistance, jointly defining on-state conduction loss profile and forward voltage drop at rated current. |
| IGT / VGT | ≤145 mA / ≤2.5 V - Maximum gate trigger current and voltage at 25 °C, setting minimum driver strength required for reliable turn-on. |
Pinout & Package
TD240N18SOFHPSA1 is housed in an industrial-standard isolated thyristor module package with solder-bond construction, 34 mm baseplate, and Al₂O₃ ceramic insulation. Mechanical mounting uses M1 screws (5 Nm ±15%), and electrical terminals conform to DIN 46244 A (2.8 × 0.8 mm).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A1 / T1 | Anode 1 (Thyristor 1) | Main current terminal for first thyristor arm; connected to AC line or load in B2/B6 bridge topologies. |
| K1 / T2 | Cathode 1 (Thyristor 1) | Main current return path for Thyristor 1; forms one half of anti-parallel pair with Thyristor 2. |
| A2 / T3 | Anode 2 (Thyristor 2) | Anode of second thyristor in anti-parallel configuration; enables bidirectional AC conduction. |
| K2 / T4 | Cathode 2 (Thyristor 2) | Cathode of second thyristor; completes complementary conduction path for full-wave phase control. |
| G1 | Gate 1 | Control input for Thyristor 1; requires ≥1 A pulse with di/dt ≥1 A/µs for latching (IL ≤400 mA). |
| G2 | Gate 2 | Independent gate input for Thyristor 2; electrically isolated from G1 and main terminals per IEC61140 Class 1. |
Key Features
| Feature | Design Value |
|---|---|
| Solder-bond chip attachment | Enables lower thermal resistance and higher power cycling reliability vs. wire-bond modules, supporting >10⁵ cycles at ΔTj = 100 K. |
| Electrically insulated baseplate | Al₂O₃ ceramic isolation rated at 3.0 kV RMS (1 min), eliminating need for additional insulating hardware in heatsink mounting. |
| High dv/dt immunity | 1000 V/µs critical off-state voltage rise rate prevents spurious turn-on during fast grid transients in industrial mains-connected systems. |
| Low conduction losses | 0.85 V VT0 + 0.9 mΩ rT yields <1.52 V on-state voltage at 500 A, reducing thermal stress and improving system efficiency in 200–300 A applications. |
| Standardized mechanical interface | DIN 46244 A terminals and M1 mounting holes ensure compatibility with legacy soft-starter and UPS rectifier chassis designs. |

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 |
|---|---|---|---|
| TT240N18SOF | Same die, identical electrical specs, but non-isolated baseplate (no Al₂O₃ insulation); RthJC = 0.0725 K/W (per arm, DC). | Requires external insulating hardware; suitable only where heatsink isolation is handled separately. | Select TT240N18SOF only when baseplate isolation is unnecessary and lower thermal resistance is prioritized over mounting simplicity. |
| TD240N16SOFHPSA1 | Lower VDRM/VRRM (1600 V); otherwise identical package, thermal, and gate characteristics. | Limited to 1000 V RMS AC systems; unsuitable for 1200 V line applications or high-voltage UPS designs. | Choose TD240N16SOFHPSA1 only for cost-sensitive 690–1000 V AC systems where 1800 V margin is not required. |
Compared with TT240N18SOF and TD240N16SOFHPSA1, TD240N18SOFHPSA1 uniquely combines 1800 V blocking capability with integrated baseplate isolation-enabling direct heatsink mounting in safety-critical 1200 V AC applications without added insulation layers or assembly steps.

FAQ
What is the maximum allowable case temperature for continuous operation?
The maximum case temperature (TC) for TD240N18SOFHPSA1 is 130 °C under continuous DC or low-frequency AC operation. This limit ensures junction temperature remains ≤140 °C when combined with the specified 0.145 K/W RthJC and appropriate heatsink thermal resistance. Exceeding 130 °C risks accelerated parameter drift and reduced lifetime.
Does this module require forced air cooling?
No-forced air cooling is not mandatory. With a heatsink thermal resistance (RthCA) of ≤0.20 K/W, TD240N18SOFHPSA1 sustains 240 A ITAVM at TC = 85 °C using passive convection. However, forced airflow improves margin: at RthCA = 0.10 K/W, full 240 A load is viable even with ambient temperatures up to 60 °C.
Can TD240N18SOFHPSA1 be used in single-phase applications?
Yes-it supports single-phase B2 (two-pulse) bridge configurations. The datasheet provides ID vs. TA curves for B2 operation, confirming up to 350 A output current with RthCA = 0.10 K/W. Gate drive must maintain independent timing for each thyristor arm to avoid shoot-through during commutation.
What is the creepage distance and why does it matter?
The creepage distance is 10 mm, measured across the insulated baseplate surface between main terminals. This meets IEC 61800-5-1 requirements for Pollution Degree 3 environments, ensuring reliable isolation in dusty, humid, or conductive-contaminant industrial settings without risk of surface tracking or flashover.
