Infineon Technologies TD180N16KOFHPSA2

Overview

TD180N16KOFHPSA2 from Infineon Technologies is a phase-control thyristor module with 1600 V repetitive peak off-state voltage (VDRM/VRRM), 180 A average on-state current (ITAVM) at TC = 85°C, and 285 A RMS on-state current (ITRMSM), designed for industrial AC power control in medium-power rectifier and motor drive systems.

For engineers reviewing the TD180N16KOFHPSA2 datasheet, TD180N16KOFHPSA2 pinout, TD180N16KOFHPSA2 application, or TD180N16KOFHPSA2 equivalent, key selection criteria include commutated turn-off time (tq = 200 µs), critical dv/dt rating (1000 V/µs), junction-to-case thermal resistance (0.096 °C/W per arm), and gate trigger parameters (IGT ≤ 150 mA, VGT ≤ 2 V).

Technical Context

This dual-thyristor module implements a B6 six-pulse bridge configuration with pressure-contact silicon pellets and aluminum nitride (AlN) internal isolation. It supports natural or forced cooling with validated thermal impedance models (ZthJC, ZthCA) for transient thermal analysis under sinusoidal and rectangular conduction angles.

The device operates with gate-controlled delay time ≤ 3 µs and requires precise gate drive timing to ensure reliable commutation in line-commutated inverters and soft-start circuits. Its 130 °C maximum junction temperature and -40...+130 °C operating range support deployment in harsh industrial environments.

FAQ

What is the maximum allowable case temperature for continuous operation?

The maximum allowable case temperature (TC) is not fixed but depends on load current and conduction angle. At ITAVM = 180 A and Θ = 180°, TC must not exceed 85°C for natural cooling or 100°C for forced cooling, as defined by the TC = f(ITAVM) curves on pages 7–8 of the datasheet. Exceeding these values risks exceeding Tvj max = 130°C.

Can TD180N16KOFHPSA2 be used in a single-phase full-wave bridge?

Yes - it is configured as two independent thyristor arms (A1/K2 and K1/A2) with isolated gates, making it suitable for single-phase B2 bridges. However, its B6-rated thermal and electrical validation means full utilization requires three modules per three-phase system; single-phase use must respect per-arm ratings and derate thermal design accordingly.

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

A minimum gate trigger voltage of 2 V and current of 150 mA must be applied for ≤ 3 µs at 25°C, per datasheet limits. For robust operation across temperature and aging, gate drivers should deliver ≥ 3 V and ≥ 300 mA peak with < 1 µs rise time, and maintain ≥ 100 mA holding current after turn-on to prevent misfiring.

Is the module electrically isolated between main terminals and gate terminals?

Yes - the module features reinforced internal isolation using aluminum nitride (AlN) ceramic, with 3.0 kV RMS insulation test voltage (1 sec) between main terminals (A/K) and gate terminals (G), and between gate terminals and case. This meets IEC 60747-5-2 requirements for industrial equipment with functional isolation.
