It may take awhile to hunt this down.
I just looked at some of my packages, though, I know what they are, One has VF, one has Z86, one has Z32.
If I didn't know what these were, I may have trouble with them.
The only thing I can suggest, is look at the other traces going to it and try and figure out what it is based on that. If it is on a circuit board.
If You find out what it is based on that, and don't know exactly the component model or manufacturer, you can select (for instance, you know it's an inverter), then goto digikey or mouser, and look at inverters and search through components and look at data sheets. All data sheets will say what Marking Code that is on that particular chip from the manufacturer.
