Max. Unit IGT VGND/LINE = -48V 0.2 5 mA IH VGATE =-48V (see note 2) 150 mA VGT at IGT 2.5 V IRG Tc=25 °CVRG =-75V Tc=70 °CVRG =-75V 5 50 µA VDGL VGATE= -48V (see note 3) 10/700 µs 1.5kV Rp=10 Ω IPP=30A 1.2/50 µs 1.5kV Rp=10 Ω IPP=30A 2/10 µs 2.5kV Rp=62 Ω IPP=38A 10 20 25 V Note 2 : See the functional holding current (IH) test circuit 2. Note 3 : See test circuit 1 for VDGL. The oscillations with a time duration lower than 50ns are not taken into account. 2 - PARAMETERS RELATED TO THE PROTECTION THYRISTOR (Tamb =25 °C) Symbol Test conditions Maximum Unit IRM Tc=25 °CVGATE/LINE = -1V VRM =-75V Tc=70 °CVGATE/LINE = -1V VRM =-75V 5 50 µA C VR =-3V F=1MHz VR =-48V F=1MHz 100 50 pF 3 - PARAMETERS RELATED TO DIODE AND PROTECTION THYRISTOR (Tamb =25 °C) 1 2 3 4 8 7 6 5 IN IN OUT OUT TIP RING GND TIP RING GATE NC In order to take advantageof the ”4 point” structure of the LCP, the TIP and RING lines go across the device. In such case, the device will eliminate the overvoltages generated by the parasitic induc- tances of the wiring (Ldi/dt), especially for very fast transients. LCP1511D 3/7 |
