Product details
Overview
TT210N14KOFHPSA1 from Infineon Technologies is a press-pack, dual-thyristor phase-control module rated for 1400 V repetitive peak off-state voltage (VDRM/VRRM), 210 A average on-state current (ITAVM at TC = 85 °C), and 6600 A non-repetitive surge current (ITSM). It features electrically insulated baseplate, 0.85 mΩ slope resistance (rT), and 0.124 K/W junction-to-case thermal resistance - designed for high-reliability industrial power control in soft starters and UPS rectifiers.
For engineers reviewing the TT210N14KOFHPSA1 datasheet, TT210N14KOFHPSA1 pinout, TT210N14KOFHPSA1 application, or TT210N14KOFHPSA1 equivalent, key selection criteria include verified VDRM/VRRM rating (1400 V), ITAVM derating across conduction angles, gate trigger thresholds (IGT ≤ 200 mA, VGT ≤ 2 V), and pressure-contact thermal performance under forced-air or liquid-cooled heatsink mounting.
Technical Context
This dual-thyristor module implements line-commutated phase-angle control with 200 µs typical turn-off time (tq) at Tvj max and 1000 V/µs critical dv/dt rating. Its pressure-contact construction eliminates wire bonds, enabling stable 125 °C maximum junction temperature operation and robust I²t handling (218,000 A²s at Tvj = 25 °C).
The module supports B2 (two-pulse) and B6 (six-pulse) bridge configurations, with validated current derating curves up to 800 A output in B6 topology at TA = 40 °C and RthCA = 0.12 K/W. Gate drive requires ≥1 A pulse with diG/dt ≥ 1 A/µs to ensure reliable latching (IL ≤ 1200 mA) and avoid false triggering (IGD ≤ 5 mA at 0.5·VDRM).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDRM / VRRM | 1400 V - Maximum repetitive blocking voltage per thyristor arm; defines AC line voltage compatibility up to 1000 V RMS systems. |
| ITAVM (TC = 85 °C) | 210 A - Continuous DC or sinusoidal conduction current per arm at case temperature of 85 °C; basis for thermal design with heatsink. |
| ITSM (10 ms) | 6600 A - Non-repetitive surge current capability; determines short-circuit withstand in motor starter crowbar events. |
| rT / VT0 | 0.85 mΩ / 1.0 V - Slope resistance and threshold voltage; used to calculate on-state losses (PTAV ≈ ITAV²·rT + ITAV·VT0) for efficiency modeling. |
| RthJC | 0.124 K/W - Junction-to-case thermal resistance per arm; enables direct calculation of ΔTj-c from power dissipation in thermal simulation. |
| (dv/dt)cr | 1000 V/µs - Minimum required snubber dv/dt immunity; dictates external RC snubber sizing to prevent false turn-on during commutation. |
| tq (typ) | 200 µs - Typical commutated turn-off time; sets minimum dead-time requirement in phase-controlled rectifier gate timing. |
Pinout & Package
TT210N14KOFHPSA1 uses an industrial-standard press-pack module package with electrically insulated AlN ceramic baseplate (17 mm creepage), 50 mm baseplate width, and M2 terminal torque (12 Nm). Mechanical mounting uses M1 screws (5 Nm ±15%).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

| Insulated Baseplate | Thermal & electrical interface | AlN-ceramic base provides 3.6 kV RMS isolation (1 sec test); mounts directly to heatsink without additional insulator. |
Key Features
| Feature | Design Value |
|---|---|
| Pressure-contact Si-pellet assembly | Eliminates bond wires and solder layers, delivering stable rT and RthJC over >10⁵ thermal cycles in industrial drives. |

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 |
|---|---|---|---|
| TT210N16KOFHPSA1 | VDRM/VRRM = 1600 V; identical ITAVM, ITSM, and thermal specs; higher blocking voltage grade. | Required 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 demands higher voltage derating. |
| TT190N14KOFHPSA1 | ITAVM = 190 A (TC = 85 °C); otherwise identical voltage, surge, and thermal ratings. | Suitable for lower-power soft starters (<75 kW) where thermal headroom is constrained by enclosure size. | Choose for cost-optimized designs with verified 190 A continuous load and reduced heatsink requirements. |
Compared with TT210N14KOFHPSA1, the 1600 V variant extends voltage capability without thermal trade-offs, while the 190 A version reduces conduction loss margin but lowers system cost and footprint - both retain identical gate drive, insulation, and mounting interfaces.

FAQ
What is the maximum allowable case temperature for continuous operation?
The TT210N14KOFHPSA1 supports continuous operation up to 125 °C case temperature (TC), as confirmed by its TC op range of –40 °C to +125 °C and validated ITAVM derating curves. At TC = 125 °C, ITAVM drops to 120 A for Θ = 180° sinusoidal conduction - this value is explicitly plotted in Figure 7 of the official technical information document.
Does this module require external snubbers for 50/60 Hz operation?
Snubbers are not mandatory for standard 50/60 Hz line-commutated operation due to the device's 1000 V/µs critical dv/dt rating and 200 µs tq - both exceed typical utility transients. However, snubbers remain recommended for highly inductive loads (e.g., large motors) or systems with fast-switching adjacent devices to suppress overshoot exceeding VDRM.
Can TT210N14KOFHPSA1 be used in anti-parallel configuration for AC switching?
Yes - its dual-thyristor architecture with fully isolated arms (A1/K1 and A2/K2) and independent gates (G1/G2) supports anti-parallel connection for bidirectional AC phase control. The insulated baseplate and 3.6 kV isolation rating ensure safe operation in such configurations without additional isolation hardware.
What is the gate drive energy requirement to ensure reliable turn-on?
Reliable latching requires a minimum gate charge of QG = IGT × tg ≥ 2 µC (based on IGT ≤ 200 mA and tg ≥ 10 µs). The datasheet specifies 1 A gate pulse with diG/dt ≥ 1 A/µs and tgd ≤ 3 µs - thus a 10 µs, 1 A pulse (10 µC) provides robust margin against temperature drift and aging effects.
