Product details
Overview
TT215N20KOFHPSA1 from Infineon Technologies is a phase-control thyristor module with pressure-contact construction, rated for 2000 V repetitive peak off-state voltage (VDRM/VRRM), 215 A average on-state current at TC = 85 °C (ITAVM), and 7000 A non-repetitive surge current (ITSM). It features electrically insulated baseplate, pre-applied thermal interface material (TIM), and is designed for high-reliability industrial power control in soft starters and static switches.
For engineers reviewing the TT215N20KOFHPSA1 datasheet, TT215N20KOFHPSA1 pinout, TT215N20KOFHPSA1 application, or TT215N20KOFHPSA1 equivalent, key selection criteria include junction-to-case thermal resistance (0.124 K/W), threshold voltage (0.95 V), slope resistance (0.92 mΩ), gate trigger current (≤200 mA), and critical dv/dt rating (1000 V/µs) under full-temperature operation.
Technical Context
This dual-thyristor module implements phase-angle control in AC power circuits using pressure-contact silicon die mounted on an AlN-insulated copper baseplate. Its 125 °C maximum junction temperature and 0.124 K/W RthJC enable stable operation in high-power rectifier and crowbar applications with forced-air or liquid-cooled heatsinks.
The device supports gate-controlled turn-on with ≤4 µs delay time and withstands 3.0 kV RMS insulation test voltage. Its 100 A/µs diT/dt and 1000 V/µs dv/dt ratings ensure robust commutation in inductive drive loads and UPS rectifiers operating at 50/60 Hz.

FAQ
What is the maximum allowable case temperature for continuous operation?
The maximum case temperature (TC) is +125 °C, but the rated ITAVM of 215 A is specified at TC = 85 °C. Derating curves in the datasheet show that at TC = 125 °C, ITAVM drops to approximately 145 A for 180° conduction, requiring careful thermal design to avoid exceeding junction limits.
Does TT215N20KOFHPSA1 require external snubber circuits?
Snubbers are not mandatory due to its 1000 V/µs (dv/dt)cr rating and AMPT design, but are recommended for highly inductive loads or rapid commutation scenarios. The datasheet provides RC snubber guidelines optimized for 50/60 Hz operation with L/R ratios typical of motor windings.
How is gate drive isolation implemented in this module?
Each gate terminal (G1/G2) is galvanically isolated from the baseplate and main terminals. Gate-cathode isolation withstands 3.0 kV RMS, and the module requires separate floating gate drivers referenced to their respective cathodes-not common-grounded drivers-to prevent unintended triggering.
Can TT215N20KOFHPSA1 be used in parallel configurations?
Parallel operation is not recommended. The module uses pressure-contact die without integrated current-sharing features, and mismatched thermal paths or gate delays can cause uneven current distribution. For higher current, use multi-module B6 bridges with individual firing control instead of paralleling arms.
