I have some problems to understand the datasheet of the transistor KSP44 (and transistor in general).
I need to control a LED strip. I want to switch it up through a transistor NPN. My transistor will be triggered by an Arduino, so I can apply maximum 20mA on the BASE of the transistor.
I have looked for a transistor, and I have found the KSP44.
I see on its Maximum Rating values that it can sink max 300mA on the COLLECTOR pin, and to switch, on my LED strip I need 150mA.
Where I have a doubted is about the Electrical Characteristics table of the datasheet. The maximum current in a saturated state of the transistor is 50mA. So could you tell me?
Can I use this transistor to sink 150mA on the COLLECTOR pin?
Thank you much.
