BD439G Overview
The DC current gain is the ratio of the base current to the collector current βdc = Ic/Ib and the DC current gain for this device is 40 @ 500mA 1V.Single BJT transistor offers maximum design flexibilSingle BJT transistory wSingle BJT transistorh a collector emSingle BJT transistorter saturation voltage of 800mV.VCE saturation indicates Ic is at maximum level (saturated), whereas vce saturation (Max) indicates there is no saturation.A high level of efficiency can be achieved if the base voltage of the emitter remains at 5V.Normally, a fuse's current rating refers to how much current it can carry without deteriorating too much, which in this case is 4A.In the part, the transition frequency is 3MHz.In extreme cases, the collector current can be as low as 4A volts.
