Engineering Advantages
- ISOPLUS i4-PAC Isolated Base: Eliminates the need for external insulation pads; simplifies heatsink assembly and reduces thermal interface resistance.
- High Surge Capability (ITSM = 3800 A): Withstands fault-current transients without requiring oversized fusing, reducing BOM cost.
- Low Threshold Voltage (VT0 = 1.05 V): Minimises conduction losses at rated current, improving system efficiency.
- Wide Junction Temperature Range (−40 °C to +125 °C): Suitable for outdoor enclosures and harsh industrial environments.
- 3600 VRMS Isolation: Meets reinforced insulation requirements for 690 V AC bus applications.
- Screw-Terminal Construction: Compatible with standard busbar and cable lug connections; no special tooling required.
System Architecture & Signal Flow
The TT210N14KOF houses two thyristors in an inverse-parallel (anti-parallel) or series configuration depending on circuit topology. In a typical three-phase AC controller, three TT210N14KOF modules form a full six-pulse thyristor bridge:
- Gate Drive: Pulse transformer or optocoupler-isolated gate driver → IGT ≤ 150 mA / VGT ≤ 3 V trigger requirement is compatible with standard SCR gate driver ICs (e.g., Infineon TCA785, ST UC3525).
- Thermal Path: Junction → Case (Rth(j-c) = 0.09 K/W) → Heatsink interface (Rth(c-s) = 0.04 K/W) → Forced-air or liquid-cooled heatsink.
- Snubber Network: RC snubber (typically 0.1 µF / 100 Ω) recommended across each thyristor for dV/dt suppression in inductive load circuits.
- Fusing: Semiconductor-grade fast-acting fuses rated to I2t ≤ 72000 A²s must be used for short-circuit protection.

Technical FAQ
Q: Can TT210N14KOF replace TT210N12KOF in my existing design?
A: Yes, with caution. The 14KOF suffix denotes 1400 V VDRM vs. 1200 V for 12KOF. The higher blocking voltage provides additional margin; verify gate drive compatibility and snubber values remain appropriate.
Q: What heatsink is recommended for continuous 210 A operation?
A: At Tj,max = 125 °C and Tambient = 40 °C, total Rth(heatsink-ambient) must be ≤ 0.30 K/W per arm. A forced-air heatsink with thermal resistance ≤ 0.25 K/W (e.g., Fischer SK 47 series or equivalent) is recommended.
Q: Is the isolated base sufficient for 690 V AC bus applications?
A: Yes. The 3600 VRMS isolation rating exceeds the reinforced insulation requirement (2 × 690 V × √2 + 1000 V ≈ 2950 V) per IEC 61800-5-1.
Q: What is the minimum gate pulse width for reliable triggering?
A: Infineon recommends a minimum gate pulse width of 10 µs at IGT = 150 mA for inductive loads. For resistive loads, 5 µs is typically sufficient.
Q: Do you offer consignment or Kanban supply agreements?
A: Yes. Contact support@konmask.com to discuss blanket orders, scheduled releases, and VMI arrangements for production volumes.
