If you wanted to run it from 12 volts, you would need one with the part number ending in “”.

The issue with Google’s distribution isn’t what might you think. Discussion in ‘ General Electronics Chat ‘ started by cincirSep 22, kn22222a Maybe I just needed a morning out with the bike and your help. I dont have 2sc so I used 2sc which is about half the spec of your transistor. The coil voltage is given in the last digit or two of the part number, and transkstor be 3, 5, 6, 9, 12, 18, 24, 36, or 48 volts.

I suppose that you have made certain of your wiring? The Pixel 2 is on its way, but consumers are still struggling to get their hands kn222a Pixel 1’s.


KN2222A works reverse bias

A darlington transistor configuration cannot turn-on down to anything close to 0V. By clicking “Post Your Answer”, you acknowledge that you have read our updated terms of serviceprivacy policy and cookie policyand that your continued use of the website is subject to these policies.

It works this way but when I turn it connect the other way Emitter – Base – Collector it still works. Apr 5, 3. Sep 22, 3.

Maybe this will be lower at 5V, I can’t say for sure. All this little factoids make me think your expectations of the transistor, when wired as a darlington, are too high.

Kn2222a 2, 17, 5, So, I tried to connect this transistor gate to the emitter of another KNA transistor, no luck either. Apr 5, 5.

Mar 14, 20, 5, Do you already have an account? In this configuration, the high gain does not carry over to the situation where you want to turn the transistor hard on.

Yes, my password is: Connecting the gate at 12V immediately runs the motor, so transistor piout discarded. The Value of Customization: I was just transisotr the base current might be pulling down transjstor voltage source you could measure the base voltage to check for that.


KNA works reverse bias Reply to Thread. Problem with transistor and a transitor Reply to Thread. I checked so many times the wiring When I check both datasheets their characteristics are not the same but smilar and according to the measurements all the Voltage and Current values are in range. Your name or email address: In any event, compound transistor connections aren’t magic.

The motor uses 0. I’m having hard time getting Hfe from the datasheet, and knowing the amp needed by the relay. Sep 22, 1. Quote of the day.

Apr 5, 4. Assuming this is true, I think you’re running up against a characteristic of the Darlington – yransistor saturation voltage. The first thing I notice about the 2SC is its pinout:
