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. 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? Looking at the datasheet, we can see a potential difference of 0. The column labelled "Test Conditions" isn't useful for you. It still has a maximum rating of mA but there's another problem. I suspect that you want to pretty-much saturate the transistor so to drive mA through the collector you will need at least 15 mA at the base by implication and I'm unsure if an Arduino pin is going to like doing this for sustained periods.

The KSP44 is not a good part to use in this application. Active Oldest Votes. How have you calculated the of hfe at 70x for mA sinked?

It is great if you can explain me. Andy aka Andy aka k 15 15 gold badges silver badges bronze badges. If the circuit relies on the transistor saturating, the hFE of the device is going to be about However, you may have sufficient voltage in your circuit to be able to drive the LEDs sufficiently without having too much transistor saturation - this then requires less base current but, if the transistor is then dropping say 3 volts when on, the power dissipated by it will be mW - can you live with this power loss?
