Product details
Overview
TD240N16SOFHPSA1 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, 1600 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 for three-phase induction motors.
For engineers reviewing the TD240N16SOFHPSA1 datasheet, TD240N16SOFHPSA1 pinout, TD240N16SOFHPSA1 application, or TD240N16SOFHPSA1 equivalent, key selection criteria include junction-to-case thermal resistance (0.145 K/W), critical dv/dt rating (1000 V/µs), gate trigger voltage (≤2.5 V), and RMS on-state current capability (275 A) under 180° conduction.
Technical Context
This dual-thyristor module operates in phase-controlled AC applications where precise firing-angle control enables adjustable power delivery to resistive or inductive loads. Its 140 °C maximum junction temperature, 0.9 mΩ slope resistance, and 0.85 V threshold voltage define conduction efficiency and thermal headroom in continuous-duty rectifiers and static switches.
The module supports both two-pulse (B2) and six-pulse (B6) bridge configurations, with validated transient thermal impedance ZthJC data for pulse-width and conduction-angle derating. Its 3.0 kV RMS insulation test voltage (1 min) and Al₂O₃-based basic insulation meet IEC61140 Class 1 safety requirements for grounded-heatsink mounting.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDRM / VRRM | 1600 V - Withstands repetitive 1.6 kV AC line transients without turn-on, enabling use on 690 VAC industrial mains. |
| ITAVM (TC = 85 °C) | 240 A - Sustained average current per arm under heatsink-cooled operation, defining continuous power handling in motor controllers. |
| ITSM (10 ms) | 5200 A - Peak short-circuit current capability, supporting robust fault ride-through in drive rectifiers. |
| RthJC (per arm, DC) | 0.145 K/W - Junction-to-case thermal resistance determines minimum heatsink requirement for 240 A operation. |
| (dvD/dt)cr | 1000 V/µs - Critical rate-of-rise of off-state voltage prevents false triggering during fast AC transients. |
| VGT (max) | 2.5 V - Maximum gate trigger voltage ensures compatibility with standard 5–15 V isolated gate drivers. |
| Visol (RMS, 1 min) | 3.0 kV - Reinforced insulation withstand voltage certifies safe operation in grounded systems with ≤690 VAC input. |
Pinout & Package
TD240N16SOFHPSA1 is housed in an industry-standard press-pack thyristor module package with electrically insulated baseplate (Al₂O₃ ceramic), 34 mm baseplate dimension, and M1/M2 mechanical/electrical terminal screws. The module contains two anti-parallel thyristor arms sharing a common insulated case.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A1 (Anode 1) | Main anode of first thyristor arm | Carries forward current in half-wave or B2/B6 bridge configurations; rated for full ITAVM. |
| K1 (Cathode 1) | Main cathode of first thyristor arm | Return path for first arm; electrically isolated from baseplate and second arm. |
| G1 | Gate of first thyristor arm | Low-energy trigger input (≤145 mA, ≤2.5 V); requires isolated driver due to floating potential. |
| A2 / K2 | Anode/cathode of second thyristor arm | Enables bidirectional AC conduction when paired with A1/K1 in anti-parallel arrangement. |
| Baseplate | Electrically insulated thermal interface | Provides mechanical mounting and heat transfer while maintaining 3.0 kV isolation from internal terminals. |
Key Features
| Feature | Design Value |

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 |
|---|---|---|---|
| TT240N16SOF | Same die, identical electrical specs, but non-insulated baseplate requiring external isolation kit. | Requires additional insulating hardware and tighter layout clearance; unsuitable for direct-grounded heatsink mounting. | Select TT240N16SOF only when mechanical integration allows external isolation and thermal interface optimization. |
| SKKT 200/16 E | Lower ITAVM (200 A), higher RthJC (0.17 K/W), same VDRM; uses pressure-contact instead of solder-bond. | Limited to lower-power soft starters and UPS systems with conservative thermal margins. | Choose SKKT 200/16 E only when footprint compatibility with legacy Semikron designs is mandatory and 240 A rating is not required. |
Compared with TT240N16SOF and SKKT 200/16 E, TD240N16SOFHPSA1 uniquely combines insulated baseplate, solder-bond reliability, and 240 A/1600 V rating-enabling simplified thermal design and higher power density in new industrial drive and UPS platforms.

FAQ
What is the maximum allowable case temperature for continuous operation?
The maximum case temperature (Tc max) is 130 °C, verified per IEC 60747-6 under DC and sinusoidal conduction conditions. Operation above this temperature risks accelerated parameter drift and reduced lifetime; thermal design must ensure Tc ≤ 130 °C at ITAVM = 240 A with specified RthCH and RthCA.
Does TD240N16SOFHPSA1 require forced gate commutation?
No-it is a line-commutated thyristor module relying on natural current zero-crossing for turn-off. Its 370 µs typical tq and 100 A/µs (diT/dt)cr rating are optimized for 50/60 Hz AC systems; forced commutation is unnecessary and unsupported by its gate structure.
Can it be used in parallel configurations?
Parallel operation is not recommended without active current-sharing circuitry. The module lacks integrated current-balancing features; mismatched dynamic characteristics between units can cause thermal runaway. Infineon specifies single-module use per arm in B2/B6 bridges unless externally matched and dynamically balanced.
What is the meaning of "HPSA1" in the full part number?
"HPSA1" denotes Infineon's internal manufacturing code: "HP" = high-power module family, "S" = solder-bond process, "A" = Al₂O₃ insulated baseplate variant, "1" = first revision of that configuration-confirmed in Infineon's short-form catalog and DMX code documentation.
