BD678AS Overview
This device has a DC current gain of 750 @ 2A 3V, which is the ratio between the collector current and the base current.A collector emitter saturation voltage of 2.8V allows maximum design flexibility.A VCE saturation indicates a maximum value of Ic (saturation), and a maximum value of VCE saturation (Max).A constant collector voltage of -4A is necessary for high efficiency.The base voltage of the emitter can be kept at -5V to achieve high efficiency.Normally, a fuse's current rating refers to how much current it can carry without deteriorating too much, which in this case is -4A.The maximum collector current is 4A volts.
