# Thermal Impedance Specification of CYPD3175-24LQX

Hello,

Please let me know a CYPD3175-24LQX (CCG3PA) specification for PKG Thermal Impedance, theta-JA and theta-JC/CA.

I cannot find it on datasheet.

Thanks,

Hi Kenichiro-san,

The CCG3PA datasheet have listed TjA and TjC which is equal to theta-JA and theta-JC/CA you are looking for. The value for 24-QFN is

TJA MAX is 19.98°C/W.

TJC MAX is 4.78°C/W.

Best Regards,

Lisa

Thanks Lisa,

Sorry it was there as you pointed.

BTW, how about max power consumption specification?

Data sheet shows TJ_max = 120 deg-C, Ta_max = 105 deg-C and the TJA = 19.98 deg/W, but it doesn't mean max power consumption = 0.75W, right?

What is the device specification of max.power consumption? And the customer system environment must be "Tj =< 120deg-C and Ta =< 105 deg-C" or "just Tj =< 120 deg-C"?

I mean whether it's or or not in case "Tj =< 120 deg-C but Ta > 105 deg-C" condition.

BR,

KURO
