Infineon Technologies TD215N22KOFTIMHPSA1

Overview

TD215N22KOFTIMHPSA1 from Infineon Technologies is a phase-control thyristor module with 2200 V repetitive peak off-state voltage (VDRM/VRRM), 215 A average on-state current at TC = 85 °C, and 7000 A non-repetitive surge current (ITSM). It uses pressure-contact technology and features pre-applied thermal interface material (TIM), enabling high-reliability power control in industrial rectifier and soft-starter systems.

For engineers reviewing the TD215N22KOFTIMHPSA1 datasheet, TD215N22KOFTIMHPSA1 pinout, TD215N22KOFTIMHPSA1 application, or TD215N22KOFTIMHPSA1 equivalent, key selection criteria include junction-to-case thermal resistance (0.124 K/W), gate trigger voltage (≤2.0 V), threshold voltage (≤0.95 V), slope resistance (≤0.92 mΩ), and insulated base plate construction for high-voltage isolation.

Technical Context

This thyristor module implements a dual-arm, press-pack design with electrically isolated aluminum nitride (AlN) baseplate and industrial-standard mechanical footprint. Its 2200 V blocking capability supports operation in 3-phase 6-pulse bridge configurations up to 800 A output current under forced-air cooling with RthCA ≤ 0.12 K/W.

The device operates with 125 °C maximum junction temperature and delivers 300 µs typical commutated turn-off time (tq) at full rated current. Gate drive requirements are defined by IGT ≤ 200 mA and VGT ≤ 2.0 V at 25 °C, with critical dv/dt rating of 1000 V/µs and di/dt rating of 100 A/µs.

FAQ

What is the maximum allowable case temperature for continuous operation?

The maximum case temperature (TC) is not specified as a standalone limit; instead, the device is rated for ITAVM = 215 A at TC = 85 °C. Operation above 85 °C reduces current rating per derating curves in the datasheet, with absolute maximum junction temperature Tvj max = 125 °C defining thermal boundary conditions.

Does TD215N22KOFTIMHPSA1 support asymmetrical firing between its two arms?

Yes - each arm has independent gate and cathode terminals (G1/K1 and G2/K2), allowing separate triggering signals. This enables asymmetrical conduction angles for specialized waveform shaping in harmonic mitigation or reactive power control applications.

How does the pre-applied TIM affect thermal performance and reworkability?

The factory-applied TIM achieves RthCH ≤ 0.015 K/W per module and eliminates manual dispensing variability. However, it is not designed for multiple removal/rework cycles; repeated disassembly degrades interface integrity and requires TIM replacement per Infineon's mounting guidelines.

What gate drive voltage and current are required for reliable turn-on at maximum junction temperature?

At Tvj = 125 °C, gate trigger voltage must exceed VGT max = 2.0 V and gate current must exceed IGT max = 200 mA under vD = 12 V. A 15 V/500 mA gate driver with <4 µs delay (tgd) ensures robust triggering across the full temperature range.
