I want to control ~150 SMD5050 LEDs (and 50 WS2811) with my UNO. I got some Toshiba K3878 transistors but I am not shure if I can use them... (there is so much info on this sheet) http://www.toshiba.com/taec/components2/Datasheet_Sync/201005/DST_2SK3878-TDE_EN_12100.pdf
What is the maximum currency these transistors can endure? How much do 150 LEDs drain? And what is the Voltage with which I can/should open the gate?
Soory for these noob questions :S
