Hi,

Thermal information is not described in the data sheet.

Could you tell me Tc, Tj, θjc spec？
Customer needs that information for design.

Best Regards,

Hi Yusuke,

Theta_ja can be found in the datasheet, and I am submitting a request for thermal information regardaring Theta_j, theta_a, and theta_c. Please wait for the results to return.

Hello Yusuke-san,

It usually takes about two weeks turn around time for a thermal simulation. I hope to reply by the 10th. Sorry for the delay.

Thanks,
Sally
