TUSB321: Tusb321 - Maximum Junction temp

Part Number: TUSB321

Dear E2E,

What is maximum Junction temp and case temp as TJ,max and TC,max?

BR,

  • The maximum junction temperature is the maximum storage temperature which is 150 degrees C. The case temperature is going to be the following formula (ambient temp)+(power dissapated)*(RθJC(top))= top of case temp which is going to be very close to ambient temperature because the power dissipated in this part is so small (100uA at 5V or 500 uW). Therefore the max case case temperature should be just above 85 degrees C if you are using this device in the max recommend ambient temperature.
