    Products Detail

    BU941 Overview


    In this device, the DC current gain is 300 @ 5A 10V, which is the ratio between the base current and the collector current.This system offers maximum design flexibility due to a collector emitter saturation voltage of 1.6V.Single BJT transistor means that Ic is at Single BJT transistors maximum value (saturated), so the vce saturation(Max) is equal to 2V @ 300mA, 12A.A 15A continuous collector voltage is necessary to achieve high efficiency.With the emitter base voltage set at 5V, an efficient operation can be achieved.As defined by current rating, the maximum current a fuse can carry without deteriorating too much is 15A for this device.Single BJT transistor is possible for the collector current to fall as low as 15A volts at Single BJT transistors maximum.

    BU941 Features


    the DC current gain for this device is 300 @ 5A 10V
    a collector emitter saturation voltage of 1.6V
    the vce saturation(Max) is 2V @ 300mA, 12A
    the emitter base voltage is kept at 5V
    the current rating of this device is 15A
