I try to lower the junction temp of a totem pole containing npn/pnp bjts. (see picture)
The unit zxgd3004E6 can give peak 8A and when working at a frequency of 500khz driving a mosfet the average current can reach 0.6A.
I need x3 more than it can give. I looked at some alternatives such as ZXTN19060 Peak 12A avearge 1.1A
But it seems that this combination has also high junction temperature.
The alternatives for low inductance cases such as SOT23 have not much more capability. I also want to avoid bigger packages because of higher inductance of bigger packages.
I had the idea if I can parallel 2 of these totem poles to achieve higher peak and avrage current rating.
My concern is timing. If one totem pole conducts a little bit late (because of temp difference. etc) . It causes a shoot through of the totem pole.
I think that the BJTs are not much dependant on temp but anyhow I am not sure?
Can I paralel them?
