Infineon Technologies IM240M6Y2BAKSA1

Overview

IM240M6Y2BAKSA1 from Infineon Technologies is a 600V, 4A 3-phase Intelligent Power Module (IPM) integrating RC-DF IGBTs, bootstrap gate drivers, and UL-certified NTC thermistor for motor drive systems. It delivers 2.3V typical V_CE(sat) at 25°C/4A, supports 3.3V logic inputs, and provides open-emitter outputs for shunt-based current sensing in compact SOP23 package.

For engineers reviewing the IM240M6Y2BAKSA1 datasheet, IM240M6Y2BAKSA1 pinout, IM240M6Y2BAKSA1 application, or IM240M6Y2BAKSA1 equivalent, key selection criteria include dV/dt-optimized switching for EMI control, -VS immunity for robust operation under negative transients, undervoltage lockout per channel, and 1900V_RMS isolation for industrial-grade safety compliance.

Technical Context

This IPM implements three independent half-bridge gate driver ICs with integrated shoot-through prevention logic and 300ns minimum dead-time insertion. Each high-side driver uses bootstrap supply (VBx–VSx) with 11.1V UVLO threshold and tolerance to –VS transients.

The module integrates low-loss RC-DF IGBTs rated for 600V blocking and 4A continuous output, with open-emitter (VR1/VR2/VR3) and high-side emitter (U/VS1, V/VS2, W/VS3) terminals enabling both single-shunt and leg-shunt current sensing topologies in 3-phase inverter designs.

Key Specifications

FAQ

What is the maximum allowable DC bus voltage for IM240M6Y2BAKSA1?

The absolute maximum blocking voltage is 600V, but the recommended maximum DC bus voltage is 450V as specified in the datasheet's "V+ (Positive bus input voltage)" description. Exceeding 450V risks premature failure due to increased stress on the integrated IGBTs and gate drivers, even though the device can momentarily withstand higher voltages under transient conditions.

Does IM240M6Y2BAKSA1 require external bootstrap diodes and capacitors?

Yes - although the module integrates bootstrap circuitry, external bootstrap diodes (fast recovery, ≥100V rating) and capacitors (typically 0.1–0.22μF X7R ceramic) must be placed close to each VB–VS pair (pins 2/18, 7/21, 12/23) to ensure reliable high-side gate drive during PWM operation and prevent cross-conduction.

How is the NTC thermistor connected and calibrated?

The UL-certified NTC connects internally between VTH (pin 11) and COM (pin 1). A pull-up resistor (typically 10kΩ to VDD or 3.3V) creates a voltage divider; the resulting analog voltage at VTH corresponds linearly to temperature per the thermistor's B-parameter curve. Calibration is factory-traceable and documented in Infineon's qualification report QI-000124.

Can IM240M6Y2BAKSA1 drive motors above 4A continuous current?

No - the 4A rating is defined at T_C = 25°C with adequate heatsinking. At higher case temperatures or with limited thermal management, derating is required per the R_TH(J-C) = 8.3°C/W spec. For sustained >4A loads, thermal simulation and validation are mandatory; exceeding ratings risks thermal runaway and irreversible IGBT degradation.
