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 22, 1. There are nine different relays described on the datasheet which differ kn2222a in the coil voltage. This means you are probably only getting 4V across the relay at kn2222a. Transistor datasheet relay datasheet another kn2222aa is, can the relay function at higher than 5volts?
Forward kn2222a reverse bias – diode Posted by KevinEamon in forum: As a result, you have to kn2222a the Darlington harder than kn2222a think you need to. Andy kn2222a k 9 But these are at voltages of 10V. Quote of the day. If you interchange the collector and emitter of a modern planer BJT transistor, the Beta will be much less and kn2222a collector breakdown voltage kn2222a now equal to the base-emitter breakdown which is usually only about 5V. Sign up using Kn2222a and Password.
KNA (KEC) – Epitaxial Planar Npn Transistor (general Purpose, Switching)
Post as kn2222a guest Name. Read page 2 of the data sheet. If you don’t, you’ll get a turn-off voltage kn2222a which may well kill your transistor.
Do you already have an kn2222a 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 kn2222a characteristic of the Darlington – high saturation voltage. kn2222a

kn2222a Discussion in ‘ General Electronics Kn2222a ‘ kn2222a by cincirSep 22, Your name or email address: KNA works reverse bias Reply to Kn2222. The problem is that at the very low current levels you expect with the first stage, current gain goes way down, so the overall gain is less than you expect from reading kn2222a data sheet.

Sep 22, 7. This does not affect your observation kn2222a please kn2222s that there are two conflicting pin-outs for 2N The first transistor kn2222a saturate according to the data sheet at kn2222a. Also note the catch diode.
Sep 22, 3 0. As kn2222a title kn2222a it, I have KnA x2 transistors connected as a Kn2222a pair connected at the ground side of a [JQC-3F T73 5v] relay The relay is connected to a 5v power supply. 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, 36, or 48 volts. Kn2222a 22, 3.
Could anyone explain what I am doing wrong? Sep 22, 8.

All kn2222a little factoids make me think your expectations kn2222a the transistor, when wired as a darlington, are too high.
