    Products Detail

    BF421-BP Overview


    DC current gain in this device equals 50 @ 25mA 20V, which is the ratio of the base current to the collector current.Saturation of VC means the Ic value is at its maximum, so vce saturation (Max) is 600mV @ 5mA, 30mA.As a result, the part has a transition frequency of 60MHz.A negative maximal voltage - Collector Emitter Breakdown can be observed in the device.

    BF421-BP Features


    the DC current gain for this device is 50 @ 25mA 20V
    the vce saturation(Max) is 600mV @ 5mA, 30mA
    a transition frequency of 60MHz
