Product details

Overview

T2180N14TOFVTXPSA1 from Infineon Technologies is a high-power, phase-control thyristor designed for industrial AC power regulation in medium- to high-voltage line-commutated converters. It delivers 2180 A average on-state current at 85 °C case temperature, 1400 V repetitive peak off-state voltage (V_DRM/V_RRM), and supports 44 kA non-repetitive surge current (I_TSM) - enabling robust operation in traction rectifiers, HVDC valve stacks, and large motor soft starters.

For engineers reviewing the T2180N14TOFVTXPSA1 datasheet, T2180N14TOFVTXPSA1 pinout, T2180N14TOFVTXPSA1 application, or T2180N14TOFVTXPSA1 equivalent, key selection criteria include verified 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 validated commutation turn-off time (250 µs).

Technical Context

This thyristor operates as a line-commutated, gate-controlled switch in phase-angle controlled rectification circuits. Its design centers on high-current conduction (5050 A RMS), low on-state voltage (1.11 V at 2 kA, T_vj = 125 °C), and precise gate control with latching current ≤1500 mA and holding current ≤300 mA - ensuring reliable turn-on under demanding transient conditions.

Thermal performance is defined by dual-sided clamping (30–65 kN), pressure-contact silicon pellet construction, and transient thermal impedance modeling (Z_thJC) across conduction angles (30°–180°). The device requires external forced-air or liquid-cooled heatsinking due to its 900 g mass and 25 mm creepage distance.

Key Specifications

Pin/Terminal	Circuit Role	Design Meaning

Gate (flat)	Control input for triggering conduction	Low-energy, isolated trigger terminal; requires ≥1 A/µs di/dt and ≤2 V gate voltage to ensure reliable latching.
Auxiliary Cathode	Secondary cathode connection for gate drive referencing	Provides low-impedance return path for gate current, improving noise immunity and reducing false triggering risk.

Key Features

FAQ

What is the maximum allowable case temperature for continuous operation?

The T2180N14TOFVTXPSA1 supports continuous operation up to 85 °C case temperature (T_C) when delivering its full 2180 A average on-state current, assuming two-sided cooling with proper clamping force (30–65 kN) and heatsink interface compliance. Exceeding this temperature requires derating per the published I_TAV vs. T_C curves for sinusoidal or rectangular waveforms.

Does this thyristor require a snubber circuit?

Yes - due to its 1000 V/µs critical dv/dt rating, the T2180N14TOFVTXPSA1 requires an RC snubber network across the anode–cathode terminals in most practical applications. This prevents spurious turn-on during rapid voltage transients, especially in inductive load switching or line-commutated inverter operation where di/dt and dv/dt stresses coexist.

Can the auxiliary cathode terminal be left unconnected?

No - the auxiliary cathode must be connected to the main cathode potential (typically via low-inductance strap) to provide a stable, low-impedance return path for gate current. Leaving it floating risks gate signal distortion, increased susceptibility to EMI, and inconsistent triggering behavior - particularly under high di/dt conditions in multi-thyristor stacks.

What gate drive specifications are required for reliable turn-on?

A minimum gate trigger current of 1 A with di/dt ≥ 1 A/µs and pulse width ≥ 20 µs is required to ensure latching at all operating temperatures. Gate voltage must not exceed 2 V (V_GT max), and peak gate power must stay within P_GM limits: 20 W for 10 ms, 40 W for 1 ms, or 60 W for 0.5 ms - enforced via series gate resistor and pulse shaping.
