Wrong! - Continue >> For a transistor, the safe operating area (SOA) is a plot of Ib versus Vce Ic versus time Ib versus Ic Ic versus Vce Correct! Wrong! - Continue >> A device is operating at Ic = 4A & Vce = 50V. For the device to operate at Ic = 20A (Without damaging), current has to increased further voltage should be increased voltage can be kept constant voltage should be reduced Correct! Wrong! - Continue >> The forward safe operating area (FSOA) pertains to the operation when the device is fired at a 50% Duty cycle the device is operated on DC the device is operated on AC The device is forward-biased Correct! Wrong! - Continue >> The SOAs are plotted always on a _________ scale logarithmic frequency time polynomial Correct! Wrong! - Continue >> For a BJT, find the maximum power dissipation when the device is safely operated at Vce = 90V and Ic = 0.5A 30 Watts 40 Watts 35 Watts 45 Watts Correct! Wrong! - Continue >> The SOAs provided by the manufacturers are for a particular duty cycle operation all the conditions multi pulse operation & all the temperature single pulse operation & a particular temperature Correct! Wrong! - Continue >> The SOA for an IGBT is plotted for Ic versus Vce Ig versus Vce Ic versus Vge Ig versus Ic Correct! Wrong! - Continue >> For MOSFET’s SOA, as the pulse width goes on increasing, the maximum voltage rating ____ & current rating ____ is constant, increases increases, decreases constant, decreases decreases, is constant Correct!
