    Products Detail

    BST40TA 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 40 @ 20mA 10V DC current gain.VCE saturation indicates Ic is at maximum level (saturated), whereas vce saturation (Max) indicates there is no saturation.Keeping the emitter base voltage at 5V 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.There is a transition frequency of 70MHz in the part.Single BJT transistor can be broken down at a voltage of 100V volts.When collector current reaches its maximum, it can reach 500mA volts.

    BST40TA Features


    the DC current gain for this device is 40 @ 20mA 10V
    the vce saturation(Max) is 500mV @ 4mA, 50mA
    the emitter base voltage is kept at 5V
    the current rating of this device is 500mA
    a transition frequency of 70MHz


    BST40TA Applications


    There are a lot of Diodes Incorporated
    BST40TA applications of single BJT transistors.
