Safe to drive 24V leds directly via 2SK2049 MOS-FET?
It should be fine to switch those LEDs with a MOSFET. As you say, the VDS and current rating for that part should be sufficient, and the VGS_on is &lt;2.5V, so you should be fine to drive the gate directly with a 3.3V IO. The only thing you'll have to adjust is that you need to put the MOSFET on the low-side of the LEDs. So, the LED anode connects directly to 24V supply, the drain of the MOSFET should connect to the LED cathode, and the source of the FET connects to ground.
