CSD16401Q5: MOSFET Transfer characteristics

Anastacio Favela

Part Number: CSD16401Q5

Hello TI,

Could you provide information on what conditions used to build this curve (Vds, pulse duration, duty cycle)?.  I am interested in finding what is the Vgs inflection point at which the IDS curves at the three different temperatures crosses. I guess higher Ids current would be used.

Best regards

    Anastacio,
    VDS is always done at 5V for these curves. That should be listed as a condition on the datasheet but it is not, so thank you for bringing this to our attention.

    I think the duty cycle and pulse duration are theoretically irrelevant in that the pulse duration is short enough so as to prevent any significant self heating and the duty cycle is long enough for the junction to fall to its regulated temperature.

    In other words, junction and case temperature should be the same for all these measurements.

    We have data up to 140A for all three curves, and the crossover point you are asking about (otherwise known as the zero temperature coefficient) occurs at ~3.1Vgs, 125A.
