Infineon Technologies TT180N16KOFHPSA1

Overview

TT180N16KOFHPSA1 from Infineon Technologies is a phase-control thyristor module with dual 180 A average on-state current per arm, 1600 V repetitive peak off-state voltage (VDRM/VRRM), and 4800 A non-repetitive surge current (ITSM) at 10 ms. It features pressure-contact silicon pellets, aluminum nitride (AlN) internal isolation, and is rated for 130 °C maximum junction temperature. It is used in industrial AC power control systems such as motor speed controllers and DC traction rectifiers.

For engineers reviewing the TT180N16KOFHPSA1 datasheet, TT180N16KOFHPSA1 pinout, TT180N16KOFHPSA1 application, or TT180N16KOFHPSA1 equivalent, key selection criteria include RMS current capability (285 A), critical dv/dt rating (1000 V/µs), gate trigger parameters (IGT ≤ 150 mA, VGT ≤ 2 V), and thermal resistance (RthJC = 0.096 °C/W per arm, DC).

Technical Context

This dual-arm thyristor module operates in phase-controlled rectification and AC switching applications. Each arm supports 180 A average on-state current at TC = 85 °C and withstands 1600 V repetitive blocking voltage in both forward and reverse directions.

It uses pressure-contact construction with AlN ceramic isolation for high thermal reliability and low transient thermal impedance. Gate triggering is optimized for robust turn-on under high dv/dt conditions (critical dv/dt = 1000 V/µs) and requires ≤150 mA trigger current at ≤2 V.

Key Specifications

Pinout & Package

TT180N16KOFHPSA1 is housed in a press-pack module package with isolated copper baseplate and two independent thyristor arms. Electrical terminals are arranged as three main power terminals (A1, K1, A2/K2 shared configuration) and two gate terminals (G1, G2), with mechanical mounting via M1 and M2 screws per DIN 46244 A standard.

FAQ

What is the maximum allowable case temperature for continuous operation?

The maximum allowable case temperature is not explicitly specified as a standalone limit; instead, the device is rated for 180 A average on-state current at TC = 85 °C. Operation above this temperature requires derating per the TC = f(ITAVM) curves on pages 7–8 of the datasheet, with absolute maximum junction temperature fixed at 130 °C.

Can TT180N16KOFHPSA1 be used in anti-parallel configuration for AC switching?

Yes - its symmetrical dual-arm structure and 1600 V bidirectional blocking capability (VDRM = VRRM) make it suitable for anti-parallel use in solid-state contactors and static AC switches. Gate drive must be isolated and synchronized to avoid shoot-through, and snubber networks are recommended for inductive loads.

What is the recommended gate drive circuit for reliable turn-on?

A gate drive delivering ≥0.6 A peak current with diG/dt ≥ 0.6 A/µs and pulse width ≥20 µs ensures robust triggering. The datasheet specifies IGT ≤ 150 mA and VGT ≤ 2 V at 25 °C, but design margins require ≥2× trigger current and ≥3× voltage under worst-case junction temperature and aging.

How does the pressure-contact construction affect mounting torque requirements?

Mounting torque for mechanical connections is specified as 6 Nm ±15% (M1) and 6 Nm ±10% (M2). Deviation beyond tolerance risks insufficient pellet clamping force, increasing on-state voltage and thermal resistance, or excessive stress causing ceramic fracture in the AlN isolation layer.
