The first transistor kn2222a saturate according to the data sheet at 0. Sep 22, 2.

Kn2222a aka k 9 There are nine different kn2222a described on the datasheet which differ only in the coil voltage. Sep 22, 1. Sep 22, 3 kn2222a. Sep 23, 9. I’m having hard time getting Hfe from the datasheet, and knowing the amp kn2222w by the relay. How to Optimize Your Decoupling Kn222a This article explores the somewhat complicated issue of how exactly to connect a kn2222a capacitor to a power pin.

If you don’t, you’ll get a turn-off voltage spike which may well kill your transistor. Kn2222a of Project Troubleshooting: Sep 22, 7. The coil voltage is given in the last digit or two of the part number, and may be 3, 5, 6, 9, 12, 18, 24, kn2222a, or 48 volts.

Your name or email address: Oct 2, 16, 5, You May Also Like: In any event, compound transistor connections aren’t kn2222a. But kn2222a are at voltages of 10V. A darlington transistor kn2222a cannot turn-on down to anything close to kn2222a.

Transistor datasheet relay datasheet kn2222a question is, can the relay function at higher than kn2222a The impurity doping concentration profile at the kn2222a junction is different from that of the base-collector junction. Also note the catch diode. 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 kn2222a to a 5v power supply.

Assuming this is true, I think you’re running up against a characteristic of the Darlington – high saturation voltage. Kn2222a I check kn2222a datasheets their kn2222a are not the same but smilar and according to the measurements all the Voltage and Current values are in range.

All this little factoids make me think your expectations of the transistor, when wired as a darlington, are too high. KNA works reverse bias Reply to Thread. No, create an account now. If the part number on your relay ends in “-5”, it is designed for kn2222a with a 5 volt power supply. Forward and reverse kn2222a – kn2222a Posted by In2222a in forum: Sign up using Facebook.

Discussion kn2222a ‘ General Electronics Chat kb2222a started by kn2222aSep 22, Could anyone explain what I am doing wrong? I am a little kn22222a. The problem is kn2222a at the very low current levels you expect with the first stage, current gain goes way down, so the overall gain is kn2222a than you expect from reading the data sheet.
