    Products Detail

    BF420-AP Overview


    As the DC current gain is the ratio of the collector current to the base current, for this device the DC current gain is 50 @ 25mA 20V.As a result of vce saturation, Ic reaches its maximum value (saturated), and vce saturation(Max) is 600mV @ 5mA, 30mA.Single BJT transistor is possible to achieve a high level of efficiency by maintaining the emSingle BJT transistorter base voltage at 5V.Its current rating is 500mA, which means that it can sustain a maximum current for an indefinite period of time without degrading too much.Parts of this part have transition frequencies of 60MHz.During maximum operation, collector current can be as low as 500mA volts.

    BF420-AP Features


    the DC current gain for this device is 50 @ 25mA 20V
    the vce saturation(Max) is 600mV @ 5mA, 30mA
    the emitter base voltage is kept at 5V
    the current rating of this device is 500mA
    a transition frequency of 60MHz
