    Products Detail

    BUL128-K Overview


    DC current gain' is equal to the ratio of the collector current to the base current, something like Ic/Ib, and this device has 14 @ 2A 5V DC current gain.VCE saturation indicates Ic is at maximum level (saturated), whereas vce saturation (Max) indicates there is no saturation.There is no device package available from the supplier for this product.Single BJT transistor shows a 400V maximal voltage - Collector EmSingle BJT transistorter Breakdown.When collector current reaches its maximum, it can reach 4A volts.

    BUL128-K Features


    the DC current gain for this device is 14 @ 2A 5V
    the vce saturation(Max) is 500mV @ 1A, 4A
    the supplier device package of TO-220AB
