This is the package variant TO-220, where tab is always connected to the centre pin, in this case drain.

Hope that helps?

The same statement as before applies to this double Schottky STPS61170CWLY : the centre pin is connected to the tab, because this is the result of the lead frame geometry. However, you can also check this again by carrying out a continuity measurement between the centre pin and the tab. If there is no mention of insulation in the data sheet, then there is no insulation inside the device.

I am sorry that this is not explicitly mentioned again in the data sheet.

Good luck!
