Infineon Technologies TD600N16KOFXPSA1

Overview

TD600N16KOFXPSA1 from Infineon Technologies is a press-pack, double-sided cooled, phase-control thyristor module rated for 1600 V repetitive peak off-state voltage (VDRM/VRRM), 600 A average on-state current (ITAVM at TC = 85°C), and 21 kA non-repetitive surge current (ITSM). It features electrically insulated baseplate, pressure-contact silicon die construction, and is designed for high-reliability industrial power control in soft starters and static switches.

For engineers reviewing the TD600N16KOFXPSA1 datasheet, TD600N16KOFXPSA1 pinout, TD600N16KOFXPSA1 application, or TD600N16KOFXPSA1 equivalent, key selection criteria include junction-to-case thermal resistance (0.055 K/W), gate trigger current (≤250 mA), critical dv/dt rating (1000 V/µs), and compatibility with forced-air or liquid-cooled heatsinks in medium-power drive rectifier systems.

Technical Context

This thyristor module implements a dual-arm, anti-parallel configuration optimized for line-commutated AC phase control. Its pressure-contact die assembly enables low thermal resistance and high short-circuit robustness, supporting commutation-safe operation up to 250 µs circuit turn-off time (tq) under 100 V reverse recovery conditions.

The device operates with a threshold voltage (VT0) of 0.8 V and slope resistance (rT) of 0.23 mΩ, yielding predictable on-state conduction loss across 0–6000 A. Gate drive requirements are defined by maximum IGT (250 mA), VGT (2 V), and critical di/dt immunity (200 A/µs), enabling reliable triggering in noisy industrial environments.

Key Specifications

Pinout & Package

FAQ

What is the maximum allowable junction temperature for TD600N16KOFXPSA1?

The maximum junction temperature (Tvj max) is 125°C, as specified in the Infineon technical information document revision 3.5. This limit must be maintained under worst-case conduction and switching loss conditions, using the provided ZthJC transient thermal impedance curves and RthCH values to calculate actual junction temperature rise above ambient or heatsink temperature.

Does TD600N16KOFXPSA1 require a heatsink, and what thermal interface is recommended?

Yes, active heatsinking is mandatory: at 600 A ITAVM, total power dissipation exceeds 1 kW per module. The XPSA1 suffix indicates pre-applied thermal interface material (TIM); no additional paste is required. For optimal performance, mount onto flat, clean, grounded heatsinks with surface roughness <1.6 µm Ra and verify contact pressure ≥0.5 MPa using the specified M1 mounting torque (6 Nm ±15%).

Can TD600N16KOFXPSA1 be used in parallel configurations?

Parallel operation is not recommended without external current-sharing measures. The device lacks integrated dynamic current balancing features, and parameter spread (e.g., VT0, rT) between units may cause unequal current distribution. If paralleling is unavoidable, use matched lots, identical gate drive timing (<100 ns skew), and individual series inductors (≥1 µH) per arm to enforce static and dynamic balance.

What gate drive voltage and current are required to reliably trigger TD600N16KOFXPSA1?

A minimum gate trigger voltage of 2 V and current of 250 mA must be applied for ≤4 µs to ensure turn-on under worst-case conditions (Tvj = 125°C, vD = 12 V). Recommended drive is a 10–20 V, 500 mA pulse with <1 µs rise time, isolated via pulse transformers or optocouplers rated for ≥3.6 kV test voltage to maintain system isolation integrity.
