I need help with this smd component (SOLVED)

Hello,
No matter how hard I tried, I could not identify either the manufacturer or the type of component shown in picture. I assume it is a mosfet but I have never seen components marked with this KS logo. Any ideas?

Can you identify the date codes on other chips? I suspect that "6224" may be some kind of date code, but it would help to see the chip in the context of its surroundings.

The component is part of a circuit board found inside a brand new plasma pen. Given its location near the primary of the voltage-elevating transformer I think it is a drive mosfet. The thing that surprises me is the difficulty to know the manufacturer based on the part logo, evidently I'm getting old and/or there are too many (chinese?) manufacturers around...

Edit: Gotta love their website:

"Kwansemi semiconductor is a technology driven integrated circuit and the power semiconductor device chip design company, by more than a dozen us/German/Japanese sea turtles and core technology research and development personnel was registered in 2010 in Taiwan, with a registered capital of one hundred million new Taiwan dollars, the company headquarters is located in hsinchu science park in Taiwan."

Yes, here in good old Germany, even the sea turtles are innovative. Hell, every time they emerge from the icy warm waters of the north sea, we gotta stop them from founding semiconductor companies by the dozens.
True story.
