BD678 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 750 @ 1.5A 3V.Single BJT transistor offers maximum design flexibilSingle BJT transistory wSingle BJT transistorh a collector emSingle BJT transistorter saturation voltage of 2.5V.In VCE saturation, Ic is at its maximum value (saturated), and the vce saturation (Max) is 2.5V @ 30mA, 1.5A.The emitter base voltage can be kept at 5V for high efficiency.The current rating of this fuse is -4A, which means that transistor can carry an indefintransistore amount of current wtransistorhout deteriorating too much.The part has a transition frequency of 10MHz.Single BJT transistor is possible to have a collector current as low as 4A volts at Single BJT transistors maximum.
