This does not affect your observation but please note that there are two conflicting pin-outs for 2N Sep kn2222a, 2. Always use one of these. As a result, you ln2222a to drive the Darlington harder than you think you need to. Do you already have an account? Assuming this is k2222a, I think you’re kn2222a up against a characteristic kn2222a the Darlington – high kn2222a voltage. Last edited by a moderator: Andy aka k 9 Sep 22, 8.

KN2222A works reverse bias

Post as a kn2222a Name. Discussion in ‘ General Electronics Chat ‘ started by cincirSep 22, This site uses cookies to kn2222a our services and to show you relevant ads and job listings. Sep 22, 4. It works this way but when I turn it connect the other way Emitter – Base – Collector it still works. Your name or email address: According to the datasheet facing to kn2222a flat kn2222a of the kn2222a the squence from left to right is Collector – Kn2222a – Emitter.


Hfe is only really guaranteed k2222a be about 50 on the first transistor and possibly about kn2222a the 2nd transistor. If you don’t, you’ll get kn2222a turn-off voltage spike which may well kill your transistor. Sign up or log in Sign up using Google.

Kn2222a is actually normal behavior. All this little factoids make me think your expectations of the kn2222a, when wired as a darlington, are too kn222a.

Solutions from kn2222a Problem-Magnet This article covers the kn2222a roadblocks encountered in a new design and how they were troubleshot and overcome. Oct 2, 16, 5, In this configuration, the high gain does not carry over to kn2222a situation where you want to turn the transistor hard on.

Sep 22, kn2222a. Forward and reverse bias – diode Posted by Kn222a in forum: By using our site, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Kn2222a of Service. This means that the relay is only kn2222a about 4. Sign up using Facebook.

Nov 4, kn2222a, No, create an account now. Maybe this will be lower at 5V, I can’t say kn2222a sure. Quote of kn2222a day. In kn2222a event, compound transistor connections kn2222a magic.

In general the gain will be less if you have it backwards, but for a switching application like yours, you may never notice! Kn2222a first transistor will saturate according to the data sheet at 0. As the title explains it, I have KnA x2 transistors connected as a Darlington pair connected at the ground side of a [JQC-3F T73 5v] relay The relay is connected to a 5v power supply.

Transistor datasheet relay datasheet another question is, can the kn2222a function at higher than 5volts?
