This does not affect your observation but please note that there are two conflicting pin-outs for 2N Maybe my cheap multimeter was messing around, maybe the USB wasn’t giving the 0.

Sep 22, 5.

Sep 23, 9. I’m going to put 8 diodes around the two H bridges thanks for the head up.

Connecting the gate at 12V immediately runs the motor, so transistor piout discarded. Digital Tattoos Bend The Limits Digital tattoos are an interesting implementation of an new category of “flexible electronics. Hence the collector and emitter are not interchangeable.

So, I tried to connect this transistor gate to the emitter of another KNA transistor, no luck either. Transistor datasheet relay datasheet another question is, can the relay function at higher than 5volts?

Sep 22, 1. Thanks for the replay. Sep 22, 7. Read page 2 of the data sheet. No, create an account now.

The first thing I notice about the 2SC is its pinout: Sep 22, 2. Problem with transistor and a motor Reply to Thread. The motor uses 0. Do you already have an account?

If the part number on your relay ends in “-5”, it is designed for use with a 5 volt power supply. Quote of the day. Yes, my password is: Switching a 12vdc motor with a transistor Posted by Rich2 in forum: And then the C was working also fine.

Thank you in advance. Feb 23, 3 0. Sep 22, 8. Forward and reverse bias – diode Posted by KevinEamon in forum: I have little electronics background so maybe I’m missing something obvious.



Yes, I certainly did check many times. Seems like it should work fine with a single transistor.

Apr 16, kn2222x, 1, Posted by mujizat in forum: Shouldn’t there be a resistor between the arduino pin and the transistor base? Capacitor, Reverse bias diode and resistor circuit Posted by 13th Warrior in forum: Last edited by a moderator: Find out in this Teardown Tuesday!

KNA works reverse bias Reply to Thread. A darlington transistor transistkr cannot turn-on down to anything close to 0V. If you don’t, you’ll get a turn-off voltage spike which may well kill your transistor.
