Infineon Technologies TD215N22KOFHPSA1

Overview

TD215N22KOFHPSA1 from Infineon Technologies is a phase-control thyristor module with dual 2200 V VDRM/VRRM rating, 215 A average on-state current at TC = 85 °C, and 7000 A non-repetitive surge capability. It employs pressure-contact technology and electrically insulated baseplate for high-reliability industrial power control in soft starters and static switches.

For engineers reviewing the TD215N22KOFHPSA1 datasheet, TD215N22KOFHPSA1 pinout, TD215N22KOFHPSA1 application, or TD215N22KOFHPSA1 equivalent, key selection criteria include junction-to-case thermal resistance (0.124 K/W), gate trigger voltage (≤2.0 V), critical dv/dt rating (1000 V/µs), and pre-applied TIM option for thermal interface optimization.

Technical Context

This dual-thyristor module operates in phase-controlled rectification and AC power regulation, supporting conduction angles from 30° to 180° in both sinusoidal and rectangular waveforms. Its pressure-contact construction ensures stable electrical contact under thermal cycling and mechanical stress.

The device features class-1 basic insulation (IEC61140) with 3.0 kV RMS isolation voltage, 125 °C maximum junction temperature, and gate-controlled turn-on with latching current ≤1200 mA and holding current ≤300 mA - enabling robust triggering in noisy industrial environments.

FAQ

What is the maximum allowable case temperature for continuous operation?

The maximum case temperature is not explicitly specified as a standalone limit; instead, the device is rated for ITAVM = 215 A at TC = 85 °C. Operation above 85 °C requires derating based on the TC = f(ITAVM) curve (Fig. 7), with absolute maximum junction temperature fixed at 125 °C and thermal resistance RthJC = 0.124 K/W per arm.

Does TD215N22KOFHPSA1 support reverse-conducting operation?

No - this is a standard phase-control thyristor module with unidirectional conduction per arm. Reverse conduction requires external anti-parallel diodes or use of reverse-conducting thyristors (RCTs), which are not implemented in this device. Each arm conducts only in the forward direction when gated.

How is gate drive isolation implemented in this module?

Gate terminals G1/K1G and G2/K2G are electrically isolated from the main power terminals (A1/K1/A2/K2) and from each other. Isolation is achieved via internal basic insulation (IEC61140 Class 1) with 3.0 kV RMS test voltage, allowing independent floating gate drivers without additional optocouplers or pulse transformers.

Can this module be used in parallel configurations?

Parallel operation is not recommended without active current-sharing circuitry. The module lacks integrated current-balancing features such as matched dynamic impedance or integrated gate resistors. Parallel use requires precise gate timing synchronization, matched thermal mounting, and external balancing reactors to avoid current imbalance and thermal runaway.
