FZT491AQTA Overview

As explained above, DC current gain takes into account the rate at which the base current flows through the collector current; therefore, DC current gain for this device is 300 @ 500mA 5V.In VCE saturation, Ic is at its maximum value (saturated), and the vce saturation (Max) is 500mV @ 100mA, 1A.Device displays Collector Emitter Breakdown (40V maximal voltage).
