TS5A3160: Junction temperature

Part Number: TS5A3160

Hello Team,

 My customer is looking for the max. Junction temperature of this part. Can you share with us the value?

Regards,


Renan

    Hi Renan,

    When using this device the max junction temperature that will be achieved can be calculated using the following formula:

    T_junction = Ambient Temp (C) + ((I_Switch^2 * R_ON) + (ICC * VCC ))* R_Theta_J_A.

    For example the max junction temp this device will reach can be used by filling out the equation with values from the datasheet:

    T_j = 85C + ((400mA^2 * 1.5) + (500nA * 5.5V)) * (165 C/W (SOT-23 PKG) OR 259 C/W (SC70 PKG)) -> ~ 147.161 C ; this is worst case when looking at the datasheet.

    The other value that can help is the max storage temperature of the device which is 150C - you can see that running the device at max recommended operating conditions will keep the device under the max storage temperature.

    For more information on this topic please see our FAQ post on the topic here: How to calculate max junction temperature (Tj max) and max power dissipation for an analog switch .

    Best,
