Hi. I am building a circuit from a schematic. The circuits purpose is to provide isolated communication between USARTS. I don't think the CPU should supply the current for the LED on the optocoupler. I have a reference schematic that calls for a 2sk941 to drive the LED. the gate connects to the microprocessor, and the collector connects to the LED cathode.
My issue is this. What the heck is a 2sk941? the datasheet calls it a L²-Π-mos. the datasheet is mostly in mandarin. I know what a Π-mos is. its a 3d fet whose particular geometry gives it exceptional short channel effects and enhanced current driving capability. at least, that is what it says in this article about it

what is the L² part about then? the schematic symbol shows like a bidirectional breakdown diode or something between the gate and source. what is this transistor? What are its special properties? can I just substitute it with a 2N2222A and forget about it?
