Explanation: On reduced pulse width values, the devices can operated on higher voltages & currents. 5. The SOAs provided by the manufacturers are for
A. single pulse operation & a particular temperature
B. multi pulse operation & all the temperature
C. all the conditions
D. a particular duty cycle operation
Answer:A
Explanation: On reduced pulse width values, the devices can operated on higher voltages & currents. 5. The SOAs provided by the manufacturers are for
A. single pulse operation & a particular temperature B. multi pulse operation & all the temperature C. all the conditions D. a particular duty cycle operation
Explanation: The manufacturer specifies the SOAs only for single pulse DC operation & a particular temperature (usually 20Degree Centigrade Scale). For actual operations, The SOA’s have to be modified using the thermal impedance charts. 6. A device is operating at Ic = 4A & Vce = 50V. For the device to operate at Ic = 20A (Without damaging),
