Insulating Multiwatt packages such as TDA7293

Mooly · 23rd February 2010, 06:53 PM

Can't recall ever seeing specific thermal washers for these outlines.
Is it a case of cutting a larger silicon sheet up

Ive used the Insulators for the to-264 or to-3p , you end up cutting a bit off the bottom as they are a bit big verticly .....

Thank you

The T0264 seems the best option.

I find it strange that none seem to exist in the correct size.
