BD679AS Overview

DC current gain' is equal to the ratio of the collector current to the base current, something like Ic/Ib, and this device has 750 @ 2A 3V DC current gain.A collector emitter saturation voltage of 2.8V ensures maximum design flexibility.A VCE saturation (Max) of 2.8V @ 40mA, 2A means Ic has reached its maximum value(saturated).Continuous collector voltage should be kept at 4A for high efficiency.An emitter's base voltage can be kept at 5V to gain high efficiency.A fuse's current rating indicates how much current it will be able to carry over an indefinite period, and this device has a current rating of (4A).As you can see, the part has a transition frequency of 10MHz.In extreme cases, the collector current can be as low as 4A volts.
