Product details
Overview
TT210N18KOFHPSA1 from Infineon Technologies is a phase-control thyristor module rated for 1800 V repetitive peak off-state voltage (VDRM/VRRM), 210 A average on-state current at TC = 85 °C, and 6600 A non-repetitive surge current (ITSM). It employs pressure-contact silicon pellet technology with electrically insulated baseplate, designed for high-reliability industrial power control in soft starters and UPS rectifiers.
For engineers reviewing the TT210N18KOFHPSA1 datasheet, TT210N18KOFHPSA1 pinout, TT210N18KOFHPSA1 application, or TT210N18KOFHPSA1 equivalent, key selection criteria include verified thermal resistance (RthJC = 0.124 K/W), gate trigger parameters (IGT ≤ 200 mA, VGT ≤ 2 V), and crowbar-capable surge rating under 10 ms pulse conditions.
Technical Context
This dual-thyristor module operates in phase-controlled AC power regulation, supporting full-wave bridge configurations (B2/B6) with commutated turn-off time (tq) of 200 µs at Tvj max. Its pressure-contact construction eliminates wire bonds, enabling stable conduction under high di/dt (150 A/µs) and dv/dt (1000 V/µs) stress.
Thermal performance is defined per arm: RthJC = 0.124 K/W (DC, per module), RthCH = 0.04 K/W (per arm), with maximum junction temperature of 125 °C and case operating range from –40 °C to +125 °C. Isolation withstand voltage is 3.6 kV RMS for 1 second.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDRM / VRRM | 1800 V - Maximum repetitive blocking voltage per thyristor arm; defines safe AC line voltage handling up to 1200 V RMS. |
| ITAVM | 210 A at TC = 85 °C - Continuous DC or sinusoidal conduction current per arm; determines heatsink sizing for steady-state operation. |
| ITSM | 6600 A at tP = 10 ms - Non-repetitive surge current capability; enables robust short-circuit and crowbar protection response. |
| VTO / rT | 1.0 V threshold voltage, 0.85 mΩ slope resistance - Defines forward conduction loss profile; used to calculate on-state power dissipation PTAV. |
| RthJC | 0.124 K/W per module - Junction-to-case thermal resistance; critical for calculating maximum allowable ambient temperature with given heatsink RthCA. |
| (diT/dt)cr | 150 A/µs - Minimum required rate of rise of on-state current to ensure reliable turn-on without spurious triggering. |
| (dvD/dt)cr | 1000 V/µs - Critical off-state voltage transient immunity; determines snubber design requirements for inductive loads. |
Pinout & Package
TT210N18KOFHPSA1 is housed in an industrial-standard press-pack module with electrically insulated aluminum nitride (AlN) baseplate, 50 mm baseplate width, and M2 terminal torque specification (12 Nm ±10%). The device contains two anti-parallel thyristor arms sharing a common isolated baseplate.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A1 / K2 | Anode of Arm 1 / Cathode of Arm 2 | Main power terminal for first thyristor arm; connected to AC line input in B2/B6 bridge topologies. |
| K1 / A2 | Cathode of Arm 1 / Anode of Arm 2 | Main power terminal for second thyristor arm; forms complementary conduction path in full-wave control. |
| G1 / G2 | Gate terminals (separate per arm) | Independent low-energy gate drive inputs; require ≥1 A pulse for latching (IL ≤ 1200 mA) and support isolated triggering. |
| Baseplate | Electrically insulated case / thermal interface | Provides mechanical mounting and heat transfer path; rated for 3.6 kV isolation; must be mounted with specified torque (12 Nm). |
Key Features
| Feature | Design Value |
|---|---|
| Pressure-contact silicon pellet | Eliminates bond wires and solder joints, delivering stable on-state voltage (VT ≤ 1.65 V) and long-term reliability under thermal cycling. |
| Electrically insulated AlN baseplate | Enables direct mounting onto common heatsinks without additional isolation hardware; supports 3.6 kV RMS insulation test voltage. |
| High di/dt immunity (150 A/µs) | Ensures robust turn-on in inductive motor drives without false triggering, reducing need for external gate snubbers. |
| Low thermal resistance (RthJC = 0.124 K/W) | Allows higher continuous current derating at elevated ambient temperatures-e.g., 175 A ITAVM at TC = 95 °C. |
| Standard industrial package footprint | Compatible with existing mounting hardware and cooling systems used for legacy TT210N series 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 |
|---|---|---|---|
| TT210N16KOFHPSA1 | Lower VDRM/VRRM (1600 V); identical ITAVM (210 A), RthJC (0.124 K/W), and package. | Suitable for 1000 V RMS AC systems only; not rated for 1200 V RMS line-to-line applications. | Select when system peak voltage remains ≤1600 V and cost optimization is prioritized over margin. |
| TT210N18KOIHPSA1 | Same voltage/current ratings but uses ceramic (Al₂O₃) instead of AlN baseplate; RthCH increases to 0.05 K/W. | Reduced thermal coupling efficiency requires larger heatsink area or lower ambient temperature for same ITAVM. | Choose only if AlN supply chain constraints exist and thermal margin can be accommodated in mechanical design. |
Compared with TT210N16KOFHPSA1 and TT210N18KOIHPSA1, TT210N18KOFHPSA1 provides the highest blocking margin (1800 V) and optimal thermal interface (AlN baseplate), making it the preferred choice for 1200 V RMS industrial drives and mission-critical UPS rectification where voltage headroom and thermal density are critical.

FAQ
What is the maximum allowable case temperature for continuous operation?
The maximum case temperature (TC) for continuous operation is +125 °C, as defined by the absolute maximum junction temperature (Tvj max = 125 °C) and thermal resistance RthJC = 0.124 K/W. Derating curves in the datasheet show ITAVM = 210 A is valid only when TC ≤ 85 °C; operation above that requires linear current reduction per published TC vs. ITAVM graphs.
Does TT210N18KOFHPSA1 require forced-air cooling?
No-forced-air cooling is not mandatory. With a heatsink thermal resistance (RthCA) of ≤0.25 K/W, natural convection cooling supports ITAVM = 210 A at TA = 40 °C. However, for ambient temperatures above 50 °C or higher power densities, forced-air or liquid cooling is recommended to maintain thermal margin and lifetime reliability.
Can this module be used in asymmetrical half-wave configurations?
No-it is designed exclusively for symmetrical full-wave operation in B2 (two-pulse) or B6 (six-pulse) bridge topologies. Asymmetrical triggering risks unequal thermal loading between arms, exceeding per-arm ITAVM ratings and accelerating wear due to unbalanced junction temperature distribution.
What gate drive voltage and current are required for reliable turn-on?
A minimum gate trigger current of 1 A (pulse width ≥20 µs) and voltage ≥2 V is required to ensure latching under worst-case conditions (Tvj = 125 °C). Recommended gate drive is 10–20 V with ≥2 A peak current to guarantee margin against parameter spread and aging effects across the full temperature range.
