I'm creating a 8x8x8 LED cube.
Each 8x8 layer of the cube, will have a transistor to switch the cathodes for the 64 leds of each layer.
64 leds at 19mA adds up to 1216mA.
The highest current transistor I have enough of is a 2n2222a.
It can switch 800mA.
By how much can i overshoot the max value when the transistor is running at a 1/8 duty cycle?
Can i connect two transistors in parallel to get a total of 1600mA?
It's a sunday, the store is closed, so suggestions to go and buy something are not helpfull at this point :p
