9 / 16 page IRSM505-025 IRSM515-025 Series 9 www.irf.com © 2014 International Rectifier November 24, 2014 Figures 5-7 show the typical current capability for this module at specified conditions. In all tests, the application board – the IRMCS1071-1-D reference board – was placed in a box to prevent cooling from ambient airflow. Figure 5 is derived from using a heat sink that maintains TC at 125°C. Figures 6-7 represent current capability for the module as used without any heat sink. ∆T JA represents the difference in temperature between the junction of the high-side V-phase Mosfet and the ambient, measured 10cm above and 6cm away from the board. Ambient temperature kept within 28-29°C. Figure 5: Maximum sinusoidal phase current vs PWM switching frequency with a heat sink. Space Vector Modulation, V+=320V, TA=28°C, TJ=150°C, TC=125°C Figure 6: Maximum sinusoidal phase current vs PWM switching frequency, no heat sink.
