Frequently Asked Questions
What is the INFINEON FF200R12MT4?
It is a 1200 V, 200 A nominal EconoDUAL 2 IGBT power module containing two fast Trench / Fieldstop IGBT4 switches, integrated freewheeling diodes and an NTC thermistor.
What is the collector-emitter voltage rating?
The maximum collector-emitter blocking voltage, VCES, is 1200 V. This is a semiconductor blocking rating, not an unrestricted continuous application bus-voltage rating.
What is the nominal current rating?
The nominal collector current is 200 A at a case temperature of 100°C, subject to junction temperature and cooling requirements. The datasheet also lists 295 A at a case temperature of 25°C under specified conditions.
Is the FF200R12MT4 a single IGBT or a dual module?
It is a dual IGBT half-bridge module, incorporating two switching devices with their respective freewheeling diodes.
What is the maximum repetitive peak collector current?
The datasheet specifies 400 A for a 1 ms repetitive current pulse under the stated conditions.
Does the module include a temperature sensor?
Yes. It includes an NTC thermistor rated at 5 kΩ at 25°C. The monitoring circuit must use the specified NTC characteristics.
What type of semiconductor technology is used?
The module uses Infineon fast Trench / Fieldstop IGBT4 technology and Emitter Controlled 4 diode technology.
What is the typical collector-emitter saturation voltage?
The typical VCE(sat) is 1.75 V at a collector current of 200 A, gate-emitter voltage of 15 V and junction temperature of 25°C. The maximum value under these conditions is 2.15 V.
What gate-drive voltage should be used?
The absolute peak gate-emitter voltage rating is ±20 V. The manufacturer characterizes switching performance using specified gate-drive conditions, including ±15 V for certain tests. A suitable gate driver and protection circuit are required.
What is the isolation test voltage?
The module has a specified isolation test voltage of 2.5 kV RMS at 50 Hz for one minute, with an insulated copper baseplate and aluminum oxide internal insulation.
Is FF200R12MT4 the same as FF200R12KT4?
No. These are different Infineon module designations and must not be treated as direct replacements. Compare the package, mechanical dimensions, terminal configuration, electrical characteristics and thermal ratings before substitution.
What should be checked before ordering?
Confirm the complete model FF200R12MT4, 1200 V blocking voltage, 200 A nominal collector current, EconoDUAL 2 AG-ECONOD-2-1 package, dual half-bridge configuration, terminal arrangement, gate-drive compatibility, NTC characteristics, and thermal management requirements against your system documentation before purchase.
