Hello~

Would you please let me know the Min./Max. value of Operating Junction Temperature??

I'm unable to find these values on "TLK1221" datasheet.

It needs for device thermal test.

Thanks... C.W. :)

Hi C.W.,

The maximum operating junction temperature for TLK1221 is 125 C, and the device's performance was characterized over the ambient (free-air) temperature range -40 C to 85 C.

Best regards,
Max

Hello, Max~

Thank you for your answer.

It's very helpful for me.

Do you know the Minimum value of operating junction temperature??

Does it assumed that minimum operating junction temperature is same as ambient temperature?

Regards... C.W. :)

C.W.,

Yes, the minimum operating junction temperature would match the minimum ambient temperature. Since the device dissipates some power, though, in reality the junction temperature will always be a little higher than the ambient temperature.

Max
