    Products Detail

    BUF420M Overview


    A VCE saturation (Max) of 500mV @ 4A, 20A means Ic has reached its maximum value(saturated).A high level of efficiency can be achieved if the base voltage of the emitter remains at 7V.This device has a current rating of 30A which corresponds to the maximum current it can carry for an indefinite period without deteriorating too much.As you can see, the part has a transition frequency of 0.1MHz.A maximum collector current of 30A volts is possible.

    BUF420M Features


    the vce saturation(Max) is 500mV @ 4A, 20A
    the emitter base voltage is kept at 7V
    the current rating of this device is 30A
    a transition frequency of 0.1MHz


    BUF420M Applications


    There are a lot of STMicroelectronics
    BUF420M applications of single BJT transistors.
