CSD18503Q5A: THERMAL INFORMATION

Part Number: CSD18503Q5A

I was looking for thermal information for CSD18503Q5A. It would be grateful if you could provide me with necessary data regarding the same at the earliest.

  • Nishmitha,
    For the most part, the only thermal information we can provide is already on the datasheet.

    The RthJA is a system level parameter so it really depends on your end application but we do give some best and worst case scenarios in the datasheet.

    The max RthJC(bottom) is 1.3degC/W.

    A transient thermal impedance curve is provided in figure 1 of the datasheet.

    While we do not have a measured value for the junction to top thermal impedance, for a SON5x6 device, you can use ~10degC/W. This is usually around an order of magnitude larger than the junction through bottom thermal impedance.
