    Products Detail

    BD677 Overview


    The DC current gain is the ratio of the base current to the collector current ?dc = Ic/Ib and the DC current gain for this device is 750 @ 1.5A 3V.With a collector emitter saturation voltage of 2.5V, it offers maximum design flexibility.Vce saturation means Ic is at its maximum value(saturated), and the vce saturation(Max) is 2.5V @ 30mA, 1.5A.If the emitter base voltage is kept at 5V, a high level of efficiency can be achieved.In definition, current rating refers to the maximum current a fuse can carry for an indefinite period without deteriorating too much, and the current rating of this device is 4A.A transition frequency of 10MHz is present in the part.Collector current can be as low as 4A volts at its maximum.

    BD677 Features


    the DC current gain for this device is 750 @ 1.5A 3V
    a collector emitter saturation voltage of 2.5V
    the vce saturation(Max) is 2.5V @ 30mA, 1.5A
    the emitter base voltage is kept at 5V
    the current rating of this device is 4A
    a transition frequency of 10MHz
