Infineon Technologies T2180N18TOFVTXPSA1

Overview

T2180N18TOFVTXPSA1 from Infineon Technologies is a high-power phase-control thyristor designed for industrial AC power regulation in medium- to high-voltage line-commutated converters, motor drives, and static VAR compensators. It delivers 2180 A average on-state current at 85 °C case temperature, 1800 V repetitive peak off-state voltage (VDRM/VRRM), and supports 44000 A non-repetitive surge current at 25 °C with 10 ms pulse width.

For engineers reviewing the T2180N18TOFVTXPSA1 datasheet, T2180N18TOFVTXPSA1 pinout, T2180N18TOFVTXPSA1 application, or T2180N18TOFVTXPSA1 equivalent, key selection criteria include gate trigger current (≤250 mA), critical dv/dt rating (1000 V/µs), junction-to-case thermal resistance (0.0125 °C/W two-sided cooling), and latching current (≤1500 mA) under defined test conditions.

Technical Context

This thyristor operates as a line-commutated, gate-controlled semiconductor switch in half- or full-wave AC phase control topologies. Its design centers on robust turn-on reliability under high di/dt (200 A/µs critical rate) and high dv/dt stress (1000 V/µs), enabled by pressure-contact silicon pellet construction and dual-side heat sinking capability.

It features a well-defined on-state characteristic (vT = 0.90 V threshold, 0.106 mΩ slope resistance at Tvj max) and precise gate triggering behavior (VGT ≤ 2 V, IGT ≤ 250 mA at 25 °C), with circuit commutated turn-off time (tq) of 250 µs typical under specified recovery conditions (vRM = 100 V, dvD/dt = 20 V/µs).

FAQ

What is the maximum allowable junction temperature for T2180N18TOFVTXPSA1?

The maximum junction temperature (Tvj max) is 125 °C, as specified in the official Infineon datasheet revision 2.0 dated 2009-03-12. This limit applies under all operating conditions including repetitive and non-repetitive stress, and must be maintained via proper heatsink design and thermal interface materials to ensure long-term reliability.

Does T2180N18TOFVTXPSA1 require a heatsink? If so, what type?

Yes - this device requires a mechanically clamped, two-sided heatsink with 30–65 kN mounting force. The TO-200AB package is designed for direct thermal contact on both anode and cathode faces; using only single-sided cooling increases RthJC by up to 85%, risking thermal runaway at rated current. Liquid-cooled or forced-air finned heatsinks are recommended.

Can T2180N18TOFVTXPSA1 be used in DC applications?

No - it is a line-commutated thyristor requiring natural current zero-crossing for turn-off. It cannot self-commutate in pure DC circuits. For DC switching, a forced-commutated device such as an IGBT module or GTO is required. Its datasheet specifies operation only in AC phase-control and rectifier configurations with defined commutation voltage and di/dt conditions.

What gate drive voltage and current are needed to reliably trigger T2180N18TOFVTXPSA1?

A minimum gate trigger current of 250 mA (IGT max) at ≤2 V gate voltage (VGT max) is required at 25 °C, with gate non-trigger voltage limited to ≤0.25 V at maximum junction temperature. Recommended gate drive uses a 1–2 A, 10–20 µs pulse with diG/dt ≥1 A/µs to ensure consistent turn-on across temperature and aging conditions.
