2ST5949 Overview
DC current gain in this device equals 80 @ 1A 5V, which is the ratio of the base current to the collector current.The collector emitter saturation voltage is 3V, giving you a wide variety of design options.Saturation of VC means the Ic value is at its maximum, so vce saturation (Max) is 3V @ 800mA, 8A.An emitter's base voltage can be kept at 6V to gain high efficiency.As a result, the part has a transition frequency of 25MHz.In extreme cases, the collector current can be as low as 17A volts.
2ST5949 Features
the DC current gain for this device is 80 @ 1A 5V
