Product details

Overview

TT600N16KOFXPSA1 from Infineon Technologies is a press-pack, double-sided cooled phase-control thyristor module rated for 1600 V repetitive peak off-state voltage (V_DRM/V_RRM), 600 A average on-state current (I_TAVM) at T_C = 85°C, and 21 kA non-repetitive surge current (I_TSM). It features electrically insulated baseplate, pre-applied thermal interface material (TIM), and pressure-contact silicon die construction-designed for high-reliability industrial power control in soft starters and static switches.

For engineers reviewing the TT600N16KOFXPSA1 datasheet, TT600N16KOFXPSA1 pinout, TT600N16KOFXPSA1 application, or TT600N16KOFXPSA1 equivalent, key selection criteria include junction-to-case thermal resistance (0.055 K/W), critical dv/dt rating (1000 V/µs), gate trigger current (≤250 mA), and 125°C maximum junction temperature-critical for derating in forced-air or liquid-cooled drive rectifier systems.

Technical Context

This thyristor module implements a dual-arm, anti-parallel configuration optimized for AC phase-angle control in medium-power industrial converters. Its pressure-contact die architecture eliminates wire bonds and enables symmetric current sharing between arms under asymmetrical load conditions.

The device operates with a threshold voltage (V_T0) of ≤0.8 V and slope resistance (r_T) of ≤0.23 mΩ, enabling low conduction losses at 600 A DC or 1050 A RMS. Its 250 µs circuit-commutated turn-off time (t_q) supports line-commutated operation in 50/60 Hz B2 and B6 bridge topologies.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DRM/V_RRM	1600 V - Withstands 1600 V repetitive forward/reverse blocking voltage per arm without conduction.
I_TAVM	600 A @ T_C = 85°C - Sustains continuous average on-state current per arm under specified heatsink conditions.
I_TSM	21000 A @ t_P = 10 ms - Handles short-circuit energy up to 2.2 MJ (I²t = 2.2×10⁶ A²s) without failure.
R_thJC	0.055 K/W - Junction-to-case thermal resistance per module defines minimum heatsink requirement for thermal design.
(dv/dt)_cr	1000 V/µs - Minimum rate of rise of off-state voltage before spurious turn-on occurs at max junction temperature.
V_T0 / r_T	0.8 V / 0.23 mΩ - On-state characteristic parameters used to calculate conduction loss: P_cond ≈ I² × r_T + I × V_T0.

Pinout & Package

TT600N16KOFXPSA1 uses an industrial-standard press-pack module package with 60 mm baseplate, electrically insulated AlN ceramic substrate, and M1 (6 Nm) mechanical mounting screws. Terminals are arranged for dual-arm configuration with isolated gate control paths.

Pin/Terminal	Circuit Role	Design Meaning

Equivalent & Alternatives

The following parts are listed as comparable options for similar phase-control thyristor module applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
TD600N16KOFXPSA1	Same die, identical electrical specs, but no pre-applied TIM; requires external thermal interface.	Suitable where TIM selection is customer-defined or thermal interface process is standardized.	Select TD600N16KOFXPSA1 when TIM material, thickness, or rework requirements mandate user-applied interface.
TT600N16KOFTMA1	Identical specs except TIM applied only to one side; single-sided cooling configuration.	Used in air-cooled or asymmetric heatsink layouts where only one face contacts heatsink.	Choose TT600N16KOFTMA1 for cost-sensitive single-sided cooling implementations without dual-heat-path requirement.

Compared with TD600N16KOFXPSA1 and TT600N16KOFTMA1, TT600N16KOFXPSA1 delivers lowest thermal interface resistance (0.0075 K/W) and highest assembly yield via factory-applied TIM on both sides-critical for high-power density, dual-cooled industrial inverters.

FAQ

What is the maximum allowable case temperature for continuous operation?

The maximum allowable case temperature (T_C) is not explicitly defined as a standalone limit; instead, the device is rated for I_TAVM = 600 A at T_C = 85°C. Operation above this temperature requires derating per the provided I_TAVM vs. T_C curves (e.g., ~400 A at T_C = 100°C for Θ = 180°). Thermal design must ensure T_vj ≤ 125°C under all load conditions.

Can TT600N16KOFXPSA1 be used in a single-phase full-wave rectifier?

Yes-it is configured as a dual-arm anti-parallel thyristor module, making it directly suitable for single-phase full-wave (B2) rectification. The datasheet provides ID vs. P_tot curves for B2 topology, supporting up to ~1200 A output current with appropriate heatsinking and R_thCA ≤ 0.12 K/W.

What gate drive voltage and current are required for reliable triggering?

A gate trigger voltage ≤2 V and current ≤250 mA at T_vj = 25°C ensures turn-on under worst-case conditions. For robust operation across temperature, gate pulses should deliver ≥1 A peak current with di/dt ≥1 A/µs, as specified in the gate characteristic curve (v_G vs. i_G) and critical di/dt rating of 200 A/µs.

Is the baseplate electrically isolated, and what is its isolation rating?

Yes-the baseplate is electrically isolated using aluminum nitride (AlN) ceramic with basic insulation (IEC 61140 Class 1). It withstands 3.6 kV RMS for 1 second and 3.0 kV RMS for 1 minute at 50 Hz, enabling safe direct mounting to grounded heatsinks without additional insulating hardware.
