TO-220 Pagkages and pin layout for PNP ,NPN transistors?

Hi everyone,

I am trying to find the pin layouts for a PNP and NPN transistor (Sk3180,Sk3181A) and I am unable to find the datasheets anywhere which show them.

Both transistors are the TO-220 package.

So I'm wondering, are all PNP and NPN transistor pin layouts the same for the TO-220 package?
