Product details
Overview
TT240N18SOFHPSA1 from Infineon Technologies is a phase-control thyristor module designed for high-power AC line switching and rectification in industrial drive systems. 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), enabling robust operation in soft starters and UPS rectifiers.
For engineers reviewing the TT240N18SOFHPSA1 datasheet, TT240N18SOFHPSA1 pinout, TT240N18SOFHPSA1 application, or TT240N18SOFHPSA1 equivalent, key selection criteria include junction-to-case thermal resistance (0.145 K/W), electrically insulated baseplate, gate trigger parameters (IGT ≤ 145 mA, VGT ≤ 2.5 V), and critical dv/dt rating (1000 V/µs).
Technical Context
This dual-thyristor module implements solder-bond technology with an industrial standard package and electrically insulated Al₂O₃ ceramic baseplate. Its design supports forced-commutated and line-commutated operation in 50/60 Hz AC systems, with a maximum junction temperature of 140 °C and case temperature limit of 130 °C.
The device features symmetrical blocking capability (VDRM = VRRM = 1800 V), low conduction losses (VT₀ ≤ 0.85 V, rT ≤ 0.9 mΩ), and high immunity to false triggering (dv/dt critical = 1000 V/µs, di/dt critical = 100 A/µs), making it suitable for high-reliability static switches and motor control rectifiers.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDRM / VRRM | 1800 V - Symmetrical repetitive peak blocking voltage ensures safe operation across full AC mains cycles in B2/B6 bridge configurations. |
| ITAVM (TC = 85 °C) | 240 A - Continuous average on-state current per arm defines thermal derating envelope for sustained load handling in drives and UPS. |
| ITSM (10 ms, Tvj = 25 °C) | 5200 A - Short-circuit surge capability enables reliable fault ride-through in motor starter applications. |
| RthJC (per arm, DC) | 0.145 K/W - Junction-to-case thermal resistance directly determines heatsink sizing for 130 °C max case temperature operation. |
| (dv/dt)cr | 1000 V/µs - Critical rate of rise of off-state voltage prevents spurious turn-on during fast transients in noisy industrial environments. |
| VT₀ / rT | 0.85 V / 0.9 mΩ - Threshold voltage and slope resistance define conduction loss profile and forward voltage drop under rated load. |
| IGT / VGT (max) | 145 mA / 2.5 V - Maximum gate trigger current and voltage specify minimum driver strength required for reliable turn-on. |
Pinout & Package
TT240N18SOFHPSA1 is housed in an industrial-standard isolated package with solder-bond construction and Al₂O₃ ceramic baseplate. The module contains two anti-parallel thyristor arms sharing a common insulated baseplate; electrical terminals are arranged for dual-arm access with separate anode/cathode/gate connections per arm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A1, K1 | Anode/Cathode of Arm 1 | Primary power terminals for first thyristor arm; rated for full ITAVM current and VDRM blocking. |
| A2, K2 | Anode/Cathode of Arm 2 | Primary power terminals for second thyristor arm; enables bidirectional AC control or full-wave rectification. |
| G1, K1 | Gate/Cathode of Arm 1 | Low-power control interface; requires ≥1 A pulse for latching, with IGT ≤ 145 mA at VD = 12 V. |
| G2, K2 | Gate/Cathode of Arm 2 | Independent gate drive path for second arm; supports phase-shifted or complementary firing schemes. |
| Baseplate | Electrically insulated thermal interface | Al₂O₃-isolated mounting surface; provides 3.0 kV RMS insulation and 10 mm creepage distance. |
Key Features
| Feature | Design Value |
|---|---|
| Solder-bond interconnect | Eliminates wire bonds to improve thermal cycling reliability and reduce parasitic inductance in high-di/dt switching. |
| Electrically insulated baseplate | Al₂O₃ ceramic isolation rated at 3.0 kV RMS (1 min), enabling direct mounting to grounded heatsinks without additional insulation. |
| High dv/dt immunity | 1000 V/µs critical rate ensures stable blocking under fast transient noise typical in industrial motor drive bus lines. |
| Low conduction loss | 0.85 V threshold voltage + 0.9 mΩ slope resistance yields <1.52 V on-state drop at 500 A, minimizing thermal stress. |
| Standard industrial package | Compatible with existing mounting hardware and heatsink footprints used for similar 200–300 A thyristor modules. |

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 |
|---|---|---|---|
| TD240N18SOF | Identical electrical specs but non-isolated baseplate; RthJC = 0.0725 K/W (per arm, DC); no internal Al₂O₃ insulation. | Requires external insulating pad or isolated mounting hardware; unsuitable where direct heatsink grounding is mandatory. | Select when thermal performance is prioritized over isolation simplicity and system-level insulation is managed externally. |
| TT330N18SOF | Higher ITAVM = 330 A (TC = 85 °C); same VDRM/VRRM = 1800 V; RthJC = 0.105 K/W (per arm, DC); 205 g weight. | Supports higher continuous loads but demands larger heatsink volume and increased mounting torque (M1 = 6 Nm). | Select when future-proofing for 30–40% higher current margin is required without changing PCB footprint or cooling architecture. |
Compared with TD240N18SOF and TT330N18SOF, TT240N18SOFHPSA1 uniquely combines baseplate isolation, 240 A rating, and standardized mechanical interface-making it optimal for space-constrained, safety-critical soft starters and UPS systems requiring simplified thermal and isolation integration.

FAQ
What is the maximum allowable case temperature for continuous operation?
The maximum case temperature (Tc max) is 130 °C, defined under DC or sinusoidal current conditions with proper heatsinking. Operation above this temperature risks accelerated parameter drift and reduced lifetime. Derating curves in the datasheet show ITAVM reduction to 180 A at Tc = 130 °C for Θ = 180° conduction.
Does TT240N18SOFHPSA1 require a heatsink? If so, what thermal resistance is recommended?
Yes-a heatsink is mandatory. With RthJC = 0.145 K/W and maximum junction temperature Tvj max = 140 °C, a heatsink with RthCA ≤ 0.20 K/W is recommended for full 240 A ITAVM operation at ambient ≤ 40 °C, assuming 0.04 K/W interface resistance (thermal paste + mounting pressure).
Can this module be used in a single-phase full-wave rectifier configuration?
Yes-it supports B2 two-pulse bridge operation. Each arm handles one half-cycle; the insulated baseplate allows series/parallel connection of multiple modules. Diagrams on page 8 of the datasheet confirm ID ratings up to 350 A for B2 configuration with RthCA = 0.15 K/W.
What gate drive circuitry is required to ensure reliable turn-on?
A gate driver must deliver ≥1 A peak current for ≥20 µs with VGT ≤ 2.5 V and IGT ≤ 145 mA at 25 °C. Recommended practice uses a pulse transformer or optocoupler-isolated driver with snubber (RC network) to suppress dv/dt-induced false triggering on the gate line.
