Infineon Technologies IM241S6T2JAKMA1

Overview

IM241S6T2JAKMA1 from Infineon Technologies is a 600 V reverse-conducting IGBT-based CIPOS™ Micro Intelligent Power Module (IPM) in DIP-29x12 package, integrating three half-bridge gate drivers, bootstrap circuitry, overcurrent protection, and NTC thermistor for temperature monitoring. It delivers low-EMI operation via slow-speed switching, supports 3.3 V/5.0 V logic inputs, and is designed for single-phase or three-phase BLDC/PMSM motor drives in fans and pumps.

For engineers reviewing the IM241S6T2JAKMA1 datasheet, IM241S6T2JAKMA1 pinout, IM241S6T2JAKMA1 application, or IM241S6T2JAKMA1 equivalent, key selection criteria include its isolated 2000 VRMS rating, accessible low-side emitter pins (NU/NV/NW) for phase current sensing, programmable fault-clear timing via RFE pin, and dV/dt-optimized switching for EMI-sensitive appliance designs.

Technical Context

This IPM implements six RC-IGBTs with integrated high-voltage IC (HVIC) gate drivers, each featuring shoot-through prevention, 300 ns minimum deadtime insertion, and Schmitt-trigger inputs with 1 µs minimum pulse width tolerance. The control section includes three independent low-side supplies (VDD1/VDD2/VDD3), three floating high-side supplies (VB(U)/VB(V)/VB(W)), and robust -50 V transient immunity on VS pins.

The module integrates an NTC thermistor referenced to VSS (VTH pin), programmable overcurrent shutdown via ITRIP (500 ns input filter), and a multifunction RFE pin supporting RC-network-based fault-clear timing, fault reporting, and enable/disable control - all compliant with industrial JEDEC47/20/22 qualification.

FAQ

What is the maximum continuous output current supported by IM241S6T2JAKMA1?

The IM241S6T2JAKMA1 supports up to 15 A RMS per phase under typical heatsink conditions (Tc = 80°C, fsw = 10 kHz). This rating assumes use of the slow-speed "J" variant, adequate copper area (≥200 cm² 2 oz Cu), and forced-air cooling. Peak current capability reaches 30 A for ≤100 ms with thermal derating applied via VTH feedback.

Can the RFE pin be used solely as a fault indicator without enabling auto-restart?

Yes - the RFE pin operates as an open-drain fault reporter by default. To disable auto-restart, omit the external RC network and connect RFE directly to a microcontroller GPIO configured as input with internal pull-up. The IPM will assert RFE low during UVLO or overcurrent, and remain latched off until the MCU actively pulls RFE low to clear the fault.

Is the NTC thermistor on VTH calibrated for direct temperature readout?

No - the VTH pin outputs raw analog voltage from the uncalibrated NTC. A two-point calibration (e.g., at 25°C and 85°C) is required to derive temperature. Infineon provides the NTC's B-parameter (3435 K) and resistance at 25°C (10 kΩ ±1%) in the datasheet, enabling standard Steinhart-Hart equation implementation in firmware.

Does IM241S6T2JAKMA1 support single-phase motor control?

Yes - the device supports single-phase configurations by using only two legs (e.g., U and V phases) while leaving W-phase inputs unconnected and tying W/VS(W) to P. The internal gate drivers remain fully functional, and features like ITRIP monitoring and VTH feedback remain active for the enabled phases.
