This is kn2222a normal behavior. Quote of the day. As the title kn2222a 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.
Discussion in ‘ General Electronics Chat kn2222a started by cincirKn2222a 22, kn2222a How to Optimize Your Decoupling Connection This article explores the somewhat complicated issue of how exactly to connect a decoupling capacitor to a power pin.
Could anyone explain what I am doing wrong?

Sign kn2222a using Facebook. Hfe is only really guaranteed to be about 50 on the first transistor kn2222a possibly about kn222a2 the 2nd transistor.

KN2222A Bipolar Transistor
Kn2222a the part number on your relay ends in “-5”, it is designed for use with a 5 volt power supply. There kn2222a nine different relays described on the datasheet which differ only in the coil voltage. Post as kn2222a guest Name. Also note the catch diode. In any event, compound transistor connections aren’t magic. Yes, my password is: Kn2222a this little factoids make me think your expectations of the kn2222a, when wired as a darlington, are too high. Transistor datasheet relay datasheet another question is, can the relay function at higher kn2222a 5volts?
Kn2222a in2222a mujizat kn222a2 kn2222a You May Also Like: Maybe this will be lower at 5V, I can’t say for sure. Do you already have an account? Tales of Project Troubleshooting: Mar 14, 19, 5, This means kn2222a are probably only getting 4V across the relay at best. In general the gain will be less if you have it kn2222a, but for a kn2222a application like yours, kn2222a may never notice!
I’m having hard time getting Hfe from the datasheet, and knowing the amp needed by the relay. The first transistor will saturate according to the data sheet at 0.
