8 / 15 page STGP7NC60HD - STGF7NC60HD - STGB7NC60HD 8/15 Figure 19: Ic vs Frequency For a fast IGBT suitable for high frequency appli- cations, the typical collector current vs. maximum operating frequency curve is reported. That fre- quency is defined as follows: fMAX = (PD - PC) / (EON + EOFF) 1) The maximum power dissipation is limited by maximum junction to case thermal resistance: PD = ∆T / RTHJ-C considering ∆T = TJ - TC = 125 °C- 75 °C = 50°C 2) The conduction losses are: PC = IC * VCE(SAT) * δ with 50% of duty cycle, VCESAT typical value @125°C. 3) Power dissipation during ON & OFF commuta- tions is due to the switching frequency: PSW = (EON + EOFF) * freq. 4) Typical values @ 125°C for switching losses are used (test conditions: VCE = 390V, VGE = 15V, RG = 3.3 Ohm). Furthermore, diode recovery en- ergy is included in the EON (see note 2), while the tail of the collector current is included in the EOFF measurements (see note 3). |
