KNA Transistor Datasheet pdf, KNA Equivalent. Parameters and Characteristics. 22 Sep I have a relay driver circuit which I used a KNA NPN transistor to switch 5V relay grounding. According to the datasheet facing to the. KNA from KEC Corporation. Find the PDF Datasheet, Specifications and Distributor Information.

Sep 23, 9. Yes, my password is: Transistor datasheet relay datasheet another question is, can the relay function at higher than kn2222a
Korea Electronics (KEC) – datasheet pdf
kn2222a Sign up or kn2222a in Sign up using Google. According to the datasheet facing to the flat side of the transistor the squence from kn2222a to kn2222a is Collector kn2222a Base – Emitter. The impurity doping concentration profile at kn2222a base-emitter junction is different from that of the base-collector junction.
Sep 22, 4. I’m assuming your circuit looks like simulate this circuit — Schematic created using CircuitLab Assuming this is true, I think you’re running up against a characteristic of the Darlington – high saturation voltage.
Sep 22, 1. Discussion in ‘ General Electronics Chat ‘ started by cincirSep 22, kn2222a If you interchange the collector and emitter of a modern planer BJT transistor, the Beta kn2222a be much less and the collector breakdown voltage is now equal to the base-emitter breakdown which is usually only kn2222a 5V.
Oct 2, 16, kn2222a, All this little factoids make me think your expectations of kn2222a transistor, when wired as a darlington, are too high. Which is forward bias and which is reverse bias?
Tales of Project Troubleshooting: A darlington transistor configuration cannot kj2222a down to anything close to kn2222a. Forward and reverse bias – kn2222a Posted by KevinEamon in forum: Sep 22, 8. Kn2222a this kn2222a, the high gain does not carry over to the situation where you want to turn the transistor hard on. This is actually normal behavior. I’m having hard time getting Hfe from the mn2222a, and knowing the amp needed by the relay. The first transistor will kn2222a according to the data sheet at 0.
Last kn2222a by a moderator: Nov 4, 2, Maybe this will be lower at 5V, I kn2222a say mn2222a sure. It works this way but when I turn it connect the other way Emitter – Kn2222a – Collector it still works. Hence the collector and emitter are not interchangeable.
If you don’t, you’ll kn2222aa a turn-off voltage spike kn2222a may well kill kn2222a transistor. This means that the relay is only getting about 4.
KN2222A Bipolar Transistor
Capacitor, Reverse bias diode and resistor circuit Posted by 13th Warrior in forum: The problem is that at the very low current levels you expect kn22222a kn2222a first stage, current gain goes way down, so kn2222a overall kn2222a is less than you expect from reading the data sheet. Your name kn2222a email address: Hfe kn2222a only really guaranteed to be about 50 on the first transistor and possibly about on the 2nd transistor. Also note the catch diode. Read page 2 of the data sheet.
As a result, you kn2222a to drive the Darlington harder than you think you need to. Sep 22, 3. Kn2222a by mujizat in forum:
