    Products Detail

    BUT90 Overview


    VCE saturation indicates Ic is at maximum level (saturated), whereas vce saturation (Max) indicates there is no saturation.Keeping the emitter base voltage at 10V can result in a high level of efficiency.According to definition, current rating describes the maximum current a fuse can carry indefinitely without deteriorating too much, and this device has no current rating.When collector current reaches its maximum, it can reach 50A volts.

    BUT90 Features


    the vce saturation(Max) is 900mV @ 7A, 70A
    the emitter base voltage is kept at 10V
    the current rating of this device is 50A


    BUT90 Applications


    There are a lot of STMicroelectronics
    BUT90 applications of single BJT transistors.
