BD544-S Overview
DC current gain in this device equals 15 @ 5A 4V, which is the ratio of the base current to the collector current.The collector emitter saturation voltage is -1V, giving you a wide variety of design options.Saturation of VC means the Ic value is at its maximum, so vce saturation (Max) is 1V @ 1.6A, 8A.An emitter's base voltage can be kept at 5V to gain high efficiency.In extreme cases, the collector current can be as low as 8A volts.
BD544-S Features
the DC current gain for this device is 15 @ 5A 4V
a collector emitter saturation voltage of -1V
the vce saturation(Max) is 1V @ 1.6A, 8A
the emitter base voltage is kept at 5V
