Infineon Technologies TT210N12KOFHPSA1

Overview

TT210N12KOFHPSA1 from Infineon Technologies is a phase-control thyristor module designed for high-power AC line switching in industrial power conversion systems. It features 1200 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), with pressure-contact construction enabling robust thermal performance and reliability in soft starters and static switches.

For engineers reviewing the TT210N12KOFHPSA1 datasheet, TT210N12KOFHPSA1 pinout, TT210N12KOFHPSA1 application, or TT210N12KOFHPSA1 equivalent, key selection criteria include junction-to-case thermal resistance (0.124 K/W), critical dv/dt rating (1000 V/µs), gate trigger parameters (IGT ≤ 200 mA, VGT ≤ 2 V), and insulated base plate design for safe high-voltage isolation.

Technical Context

This dual-thyristor module operates in B2 (two-pulse) or B6 (six-pulse) bridge configurations for AC phase-angle control. Its pressure-contact die attachment ensures low thermal resistance and stable conduction under high RMS current stress, supporting continuous operation up to 125 °C junction temperature.

The device delivers precise turn-on timing (tgd ≤ 3 µs) with controlled di/dt (150 A/µs) and dv/dt (1000 V/µs) immunity, enabling reliable triggering in noisy industrial environments. Its electrically insulated AlN-ceramic base plate provides 3.0 kV RMS insulation test voltage and eliminates need for additional isolation hardware.

FAQ

What is the maximum allowable case temperature for continuous operation?

The maximum allowable case temperature (TC) is not explicitly specified as a standalone limit; instead, the device is rated for ITAVM = 210 A at TC = 85 °C. Operation at higher case temperatures is permissible only if junction temperature remains ≤125 °C, which requires derating based on measured RthJC and heatsink thermal resistance. Thermal simulation using ZthJC transient curves (page 5) is recommended for non-DC loads.

Does TT210N12KOFHPSA1 require forced cooling?

Forced cooling is not mandatory but strongly recommended for full-rated operation. At ITAVM = 210 A and ambient temperature of 40 °C, a heatsink with RthCA ≤ 0.12 K/W is required to maintain TJ ≤ 125 °C-achievable only with active airflow or liquid cooling. Natural convection is insufficient beyond ~80 A continuous load.

Can this module be used in single-phase applications?

Yes-TT210N12KOFHPSA1 supports both single-phase (B2 two-pulse) and three-phase (B6 six-pulse) configurations. In single-phase use, one arm handles full load current while the other remains unused or configured for anti-parallel operation; derating is not required, as thermal and electrical ratings apply per arm.

What gate drive voltage and current are needed for reliable triggering?

A minimum gate trigger voltage of 2 V and current of 200 mA must be delivered within a 20 µs pulse width to ensure latching at all operating temperatures. Recommended gate drive uses a pulse transformer or isolated gate driver delivering ≥5 V/≥500 mA peak to accommodate aging and parameter spread, with di/dt ≥1 A/µs to meet the 150 A/µs critical turn-on rate.
