BD678AS Overview
This device has a DC current gain of 750 @ 2A 3V, which is the ratio between the base current and the collector current.Single BJT transistor has a collector emSingle BJT transistorter saturation voltage of 2.8V, which allows maximum flexibilSingle BJT transistory in design.Single BJT transistor means that Ic is at Single BJT transistors maximum value (saturated), so the vce saturation(Max) is equal to 2.8V @ 40mA, 2A.For high efficiency, the continuous collector voltage must be kept at -4A.A high level of efficiency can be achieved if the base voltage of the emitter remains at -5V.According to definition, current rating describes the maximum current a fuse can carry indefinitely without deteriorating too much, and this device has no current rating.A maximum collector current of 4A volts can be achieved.
