Infineon Technologies TT215N22KOFHPSA1

Overview

TT215N22KOFHPSA1 from Infineon Technologies is a phase-control thyristor module designed for high-power AC line switching and rectification in industrial drive systems. It features 2200 V repetitive peak off-state voltage (VDRM/VRRM), 215 A average on-state current at TC = 85 °C, 7000 A non-repetitive surge current, and 0.124 K/W junction-to-case thermal resistance - enabling robust operation in soft starters and static power controllers.

For engineers reviewing the TT215N22KOFHPSA1 datasheet, TT215N22KOFHPSA1 pinout, TT215N22KOFHPSA1 application, or TT215N22KOFHPSA1 equivalent, key selection criteria include verified VDRM rating, ITAVM derating vs. conduction angle, thermal interface compatibility, and gate trigger threshold compliance under worst-case junction temperature.

Technical Context

This double-sided press-pack thyristor module implements pressure-contact technology with electrically insulated aluminum nitride (AlN) baseplate, supporting bidirectional blocking and forced-commutated turn-off in B2/B6 bridge configurations. Its 125 °C maximum junction temperature and 3.6 kV insulation test voltage (1 sec) meet IEC 61140 Class 1 safety requirements for industrial mains-connected equipment.

The device delivers precise phase-angle control via gate-triggered conduction with 200 mA max IGT and 2.0 V max VGT at 25 °C, while maintaining <50 mA off-state leakage at rated VDRM and Tvj max. Critical dv/dt capability of 1000 V/µs and di/dt rating of 100 A/µs ensure reliable commutation in inductive load applications.

FAQ

What is the maximum allowable case temperature for continuous operation?

The maximum case temperature (TC) is not directly specified as a standalone limit; instead, the device is rated for ITAVM = 215 A at TC = 85 °C. Operation above 85 °C requires derating per the published ITAVM vs. TC curve (Fig. 7), with absolute maximum junction temperature (Tvj max) fixed at 125 °C. Thermal design must ensure RthJC + RthCH + RthHA keeps Tvj ≤ 125 °C under worst-case load and ambient conditions.

Does TT215N22KOFHPSA1 require forced cooling?

No, forced cooling is not mandatory, but natural convection is insufficient for full ITAVM loading. At 215 A, the module dissipates ~420 W per arm (based on vT = 1.8 V and rT = 0.92 mΩ). A heatsink with RthHA ≤ 0.12 K/W is required for TC ≤ 85 °C in still air; liquid or forced-air cooling is recommended for higher power density layouts or elevated ambient temperatures.

Can this module be used in parallel configurations?

Parallel operation is not recommended without active current balancing. The module lacks integrated current-sharing features such as matched dynamic impedance or integrated gate drive synchronization. Parallel use introduces risk of thermal runaway due to parameter spread in V(TO) and rT. For higher current systems, Infineon recommends using higher-rated single modules (e.g., TT330N series) rather than paralleling TT215N units.

What gate drive voltage and current are required for reliable turn-on?

A minimum gate trigger current of 200 mA (IGT max) and voltage of 2.0 V (VGT max) at 25 °C is required for guaranteed turn-on. Drive circuits must deliver ≥300 mA peak current with <4 µs delay (tgd max) and sustain ≥10 V during the entire gate pulse (≥20 µs). Isolated gate drivers with 2500 Vrms reinforcement are mandatory due to the floating cathode/anode potentials in bridge configurations.
