Infineon Technologies T880N16TOFXPSA1

Overview

T880N16TOFXPSA1 from Infineon Technologies is a high-power phase-control thyristor designed for industrial AC power regulation in medium-voltage motor drives, static VAR compensators, and DC traction rectifiers. It delivers 880 A average on-state current at 85 °C case temperature, 1600 V repetitive peak off-state voltage (VDRM/VRRM), and withstands 17.5 kA non-repetitive surge current (ITSM) with 1530 × 10³ A²s I²t rating.

For engineers reviewing the T880N16TOFXPSA1 datasheet, T880N16TOFXPSA1 pinout, T880N16TOFXPSA1 application, or T880N16TOFXPSA1 equivalent, key selection criteria include gate trigger current (≤250 mA), critical dv/dt immunity (1000 V/µs), thermal resistance (0.032 °C/W junction-to-case, two-sided cooling), and 125 °C maximum junction temperature under continuous conduction.

Technical Context

This thyristor operates as a line-commutated, gate-controlled semiconductor switch in half-wave or full-wave AC phase-angle control topologies. Its 200 A/µs critical di/dt and 1000 V/µs critical dv/dt ensure robust turn-on stability and immunity to false triggering in high-noise industrial environments with inductive loads.

The device uses silicon pellet construction with pressure-contact packaging and dual-side heat sinking capability. Its on-state characteristic follows a defined polynomial (A=1.046, B=2.313×10⁻⁴, C=−5.398×10⁻², D=8.494×10⁻³) enabling precise conduction loss modeling across 200–4400 A load range at 125 °C junction temperature.

FAQ

What is the recommended gate drive circuit for T880N16TOFXPSA1?

A pulse transformer or optocoupler-based gate driver delivering ≥1 A peak current with <4 µs delay (tgd) and <2.2 V gate trigger voltage (VGT) is required. Gate resistor must limit IGT to ≤250 mA while ensuring diG/dt ≥1 A/µs. Auxiliary cathode (pin 5) must be tied directly to gate driver return to minimize loop inductance.

Can T880N16TOFXPSA1 be used in forced-commutated circuits?

No-it is a line-commutated thyristor without inherent turn-off capability. It relies on natural current zero-crossing for commutation. Forced-commutation requires GTOs, IGCTs, or IGBTs. Using this device in chopper or inverter topologies without external commutation circuitry will result in latch-up and destruction.

What is the minimum clamping force required for thermal performance?

The specified clamping force range is 10.5–21 kN. Below 10.5 kN, RthJC degrades nonlinearly-e.g., at 8 kN, junction-to-case resistance increases by >40%, risking thermal runaway at rated ITAV. Use calibrated hydraulic tools and follow Infineon's torque sequence per Application Note AN2008-01.

How does conduction angle affect maximum allowable case temperature?

At Θ = 180° (full conduction), TC max = 85 °C for ITAV = 880 A. At Θ = 30°, TC max rises to 120 °C for same ITAV due to reduced RMS heating. Derating curves in datasheet page 6 show TC vs. ITAV for Θ = 30°–180°; use two-sided cooling data for all calculations.
