BC449A Overview

DC current gain in this device equals 120 @ 2mA 5V, which is the ratio of the base current to the collector current.The collector emitter saturation voltage is 125mV, giving you a wide variety of design options.Saturation of VC means the Ic value is at its maximum, so vce saturation (Max) is 250mV @ 10mA, 100mA.Keeping the emitter base voltage at 5V allows for a high level of efficiency.The current rating of this fuse is 300mA, which means that transistor can carry an indefintransistore amount of current wtransistorhout deteriorating too much.The part has a transition frequency of 200MHz.A maximum collector current of 300mA volts is possible.
