Product details
Overview
TT92N08KOFKHPSA1 from Semikron is a phase-control thyristor module configured as a dual reverse-blocking (B2) or six-pulse bridge (B6) AC power switching device, rated for 1200 V repetitive peak off-state voltage (VDRM/VRRM), 92 A average on-state current (ITAVM) at TC = 85°C, and 2050 A non-repetitive surge current (ITSM). It delivers precise line-synchronized AC power regulation in industrial heating systems, motor speed controllers, and static VAR compensators.
For engineers reviewing the TT92N08KOFKHPSA1 datasheet, TT92N08KOFKHPSA1 pinout, TT92N08KOFKHPSA1 application, or TT92N08KOFKHPSA1 equivalent, key selection criteria include gate trigger current (IGT ≤ 120 mA), critical dv/dt rating (1000 V/µs), thermal resistance junction-to-case (0.185 °C/W per module), and forced-cooling-compatible mounting torque (4 Nm).
Technical Context
This thyristor module integrates two press-pack silicon pellets with aluminum nitride (AlN) internal isolation in a single housing, enabling bidirectional blocking and high-reliability operation in phase-angle controlled AC circuits. Its gate-controlled delay time (tgd ≤ 3 µs) and critical di/dt capability (150 A/µs) support fast, deterministic turn-on under high dv/dt stress.
The module supports both natural and forced cooling configurations, with transient thermal impedance ZthJC characterized for sinusoidal and rectangular conduction angles (0°–180°). Its 2.5 kV RMS insulation test voltage (1 min) and 12.5 mm creepage distance meet IEC 60747-6 and industrial safety requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDRM / VRRM | 1200 V - Maximum repetitive forward/reverse blocking voltage; defines safe AC line voltage range up to 850 V RMS. |
| ITAVM (TC = 85°C) | 92 A - Continuous average on-state current per arm; determines steady-state power handling in B2/B6 rectifier topologies. |
| ITSM (10 ms) | 2050 A - Non-repetitive surge current capacity; enables robust short-circuit withstand in motor drive DC-link protection. |
| (dv/dt)cr | 1000 V/µs - Critical rate of rise of off-state voltage; prevents false triggering during fast transients in inductive loads. |
| RthJC (per module) | 0.185 °C/W - Junction-to-case thermal resistance; sets minimum heatsink requirement for 92 A continuous operation. |
| vT (max, 300 A) | 1.62 V - Maximum on-state voltage drop; directly determines conduction loss (PTAV ≈ 148 W at 92 A, Θ = 180°). |
| IGT / VGT (max) | 120 mA / 1.4 V - Gate trigger current/voltage threshold; defines compatible driver output capability and snubber design. |
Pinout & Package
TT92N08KOFKHPSA1 uses a press-pack module package with isolated copper baseplate, AlN ceramic isolation, and M1 mechanical terminals (4 Nm torque) plus DIN 46244 A control terminals (2.8 × 0.8 mm). The module contains two independent thyristor arms sharing common cathode/anode terminals depending on configuration (B2 or B6).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A1 / K2 | Anode 1 / Cathode 2 | Primary AC input/output terminals for B2 bridge or B6 three-phase leg; rated for 1200 V and 92 A avg. |
| K1 / A2 | Cathode 1 / Anode 2 | Complementary AC terminals; polarity reversal enables reverse-blocking operation in full-wave phase control. |
| G1 / G2 | Gate 1 / Gate 2 | Isolated low-power control inputs; require ≤120 mA trigger current and tolerate ≤0.2 V non-trigger voltage. |
| Case | Thermal & Electrical Reference | Electrically isolated copper baseplate; serves as thermal interface and must be mounted with 4 Nm torque to heatsink. |
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 |
|---|---|---|---|
| SKKT 92/12 | Same VDRM (1200 V), lower ITAVM (85 A @ TC = 85°C), higher RthJC (0.21 °C/W), TO-247-3L gate layout. | Requires larger heatsink area; limited to lower-duty-cycle heating applications. | Select when gate drive compatibility with standard TO-247 drivers is required and thermal margin allows 7 A derating. |
| TT100N12KOF | Higher VDRM (1200 V), higher ITAVM (100 A @ TC = 85°C), same RthJC (0.185 °C/W), identical press-pack package. | Supports 8 A higher continuous current without thermal redesign; suitable for upgraded power stages. | Select when system-level power demand increases beyond 92 A but mechanical footprint and cooling must remain unchanged. |
Compared with SKKT 92/12, TT92N08KOFKHPSA1 offers +7 A current headroom and superior thermal performance; versus TT100N12KOF, it trades 8 A of ITAVM for tighter gate trigger tolerance (120 mA vs. 150 mA), improving noise immunity in EMI-heavy environments.

FAQ
What is the maximum allowable case temperature for continuous operation?
The maximum case temperature (TC) is 85°C for rated ITAVM = 92 A. At higher ambient temperatures, derating is required: TC must not exceed 130°C under any condition, and the module's thermal resistance (RthJC = 0.185 °C/W) mandates heatsink design that maintains this limit under worst-case load and cooling conditions.
Can TT92N08KOFKHPSA1 be used in a six-pulse (B6) configuration?
Yes - the module is explicitly rated for B6 operation per its datasheet, supporting three-phase full-wave rectification. Each arm handles one phase leg; total output current depends on RthCA and cooling method, with up to 160 A RMS achievable under forced-air cooling with KM14 heatsink and Papst 4650N fan.
What gate drive voltage and current are required for reliable turn-on?
A minimum gate trigger voltage of 1.4 V and current of 120 mA must be applied for guaranteed turn-on at Tvj = 25°C and vD = 6 V. Gate pulses must exceed 20 µs duration and maintain ≥0.6 A/µs diG/dt to ensure latching (IL = 620 mA); gate non-trigger voltage must stay below 0.2 V to prevent spurious firing.
How does the module handle voltage transients during commutation?
The module withstands 1000 V/µs critical dv/dt without false triggering due to its optimized gate-cathode geometry and internal shielding. During forced commutation, its circuit-commutated turn-off time (tq = 150 µs typ.) and 1300 V non-repetitive reverse surge rating (VRSM) ensure safe recovery in inductive load switching.
