Product details
Overview
TT104N12KOFHPSA1 from Infineon Technologies is a phase-control thyristor module designed for high-power AC line switching and rectification in industrial drive systems. It features 1400 V repetitive peak off-state voltage (VDRM/VRRM), 102 A average on-state current at 85°C case temperature (ITAVM), 2050 A non-repetitive surge current (ITSM), and 0.35 K/W junction-to-case thermal resistance (RthJC). It is used in soft starters, static transfer switches, and UPS rectifiers where robust bidirectional power control is required.
For engineers reviewing the TT104N12KOFHPSA1 datasheet, TT104N12KOFHPSA1 pinout, TT104N12KOFHPSA1 application, or TT104N12KOFHPSA1 equivalent, key selection criteria include verified gate trigger parameters (IGT ≤ 120 mA, VGT ≤ 1.4 V), critical dv/dt rating (1000 V/µs), conduction angle–dependent thermal derating, and pressure-contact construction enabling high reliability under cyclic thermal stress.
Technical Context
This dual-thyristor module implements a press-pack, electrically insulated baseplate design with AlN ceramic isolation (Class I, IEC61140) and 2.5 kV RMS insulation test voltage. Its 180° sinusoidal conduction capability supports full-wave phase-controlled rectification in B2 and B6 bridge topologies.
The device operates with a maximum junction temperature of 140°C and requires precise gate drive timing (tgd ≤ 3 µs) and controlled di/dt (≥150 A/µs) to ensure reliable turn-on. Thermal transient impedance ZthJC is analytically modeled across seven RC network elements for accurate pulsed-loss prediction.
Key Specifications

Pinout & Package
TT104N12KOFHPSA1 is housed in an industrial-standard press-pack module with electrically insulated aluminum nitride (AlN) baseplate and 20 mm mounting height. Terminal layout follows dual-arm configuration: two main AC terminals (A1/K1 and A2/K2) and two isolated gate terminals (G1 and G2), each rated for M2 screw connection (4 Nm torque).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A1 / K1 | Anode 1 / Cathode 1 | Main current path for first thyristor arm; connected in anti-parallel pair for AC phase control. |
| A2 / K2 | Anode 2 / Cathode 2 | Main current path for second thyristor arm; forms complete bidirectional switching cell with A1/K1. |
| G1 | Gate 1 | Isolated low-energy control input for first thyristor; requires ≥0.6 A/µs diG/dt for reliable turn-on. |
| G2 | Gate 2 | Isolated low-energy control input for second thyristor; galvanically separated from G1 and baseplate. |
Key Features
| Feature | Design Value |
|---|---|
| Pressure contact technology | Eliminates wire bonds and solder joints; ensures stable contact resistance and cycle life >10⁵ thermal cycles. |
| Electrically insulated baseplate | AlN ceramic isolation rated 2.5 kV RMS; enables direct mounting to common heatsink without external insulators. |
| High dv/dt immunity | 1000 V/µs critical off-state voltage rise rate; reduces need for complex snubbers in fast-switching AC controllers. |
| Low conduction losses | V(TO) = 0.85 V and rT = 2.43 mΩ; delivers <1.73 V forward drop at 300 A, minimizing thermal load in high-current rectifiers. |

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 |
|---|---|---|---|
| TT104N14KOFHPSA1 | Higher VDRM/VRRM (1600 V) but identical ITAVM (102 A), RthJC (0.35 K/W), and package. | Preferred for 1150 V AC line systems or enhanced safety margin in 690 V industrial grids. | Select when system peak line voltage exceeds 1400 V or long-term reliability under overvoltage transients is prioritized. |
| TD104N12KOFHPSA1 | Same voltage/current ratings but uses single-arm configuration (not dual-arm); lacks integrated anti-parallel pairing. | Requires external complementary thyristor for AC phase control; not drop-in replaceable in B2/B6 bridges. | Choose only for unidirectional DC applications or custom dual-device layouts where independent arm control is needed. |
Compared with TT104N12KOFHPSA1, the TT104N14KOFHPSA1 offers higher blocking voltage without thermal or packaging trade-offs, while the TD104N12KOFHPSA1 sacrifices integration for modularity-making the TT104N12KOFHPSA1 optimal for space-constrained, high-reliability AC power control.

FAQ
What is the maximum allowable case temperature for continuous operation?
The maximum case temperature (Tc op) is +130°C, with a maximum junction temperature (Tvj max) of +140°C. Operation above 85°C case temperature requires derating of ITAVM per the published thermal curves-e.g., at TC = 100°C, ITAVM drops to approximately 75 A per arm based on RthJC = 0.35 K/W and thermal modeling.
Does TT104N12KOFHPSA1 require forced cooling?
Forced cooling is not mandatory but strongly recommended above 60 A continuous per arm. Natural convection is viable only with large heatsinks achieving RthCA ≤ 0.15 K/W; typical industrial designs use finned heatsinks with fan-assisted airflow to maintain TC ≤ 85°C at full 102 A rating.
How is gate drive isolation implemented in this module?
Each gate terminal (G1, G2) is galvanically isolated from the baseplate and main terminals by internal creepage distance ≥12.5 mm and reinforced AlN ceramic insulation. Gate drive circuits must provide ≥2.5 kV RMS isolation and comply with IEC 61800-5-1 for functional safety in drive applications.
Can TT104N12KOFHPSA1 be used in parallel configurations?
Parallel operation is not recommended due to inherent static and dynamic current-sharing imbalances between press-pack thyristors. Infineon specifies this module for single-arm or dual-arm (integrated anti-parallel) use only; paralleling requires external balancing resistors and matched gate drive timing, which voids warranty and violates datasheet usage guidelines.
