Dont forget to put a diode across the motor to protect your 2sc Home Questions Tags Users Unanswered. Apr 5, 4. Apr 16, 3, 1, The first thing I notice about the 2SC is its pinout: Create a no-fly zone!
Problem with transistor and a motor
Digital Tattoos Bend The Limits Digital tattoos are an interesting implementation of an new category of “flexible electronics. I checked so many times the wiring I am a little confused. Sep 22, 6. No, create an account now.
I’m having hard time getting Hfe from the datasheet, and knowing the amp needed by the relay. Always use one of these. Connecting the gate at 12V immediately runs the motor, so transistor piout discarded. This is actually normal behavior.

In general the gain tranzistor be less if you have it backwards, but for a switching application like yours, you may never notice!

Apr 6, transustor. I have little electronics background so maybe I’m missing something obvious. Apr 5, 1. Sep 22, 2. The impurity doping concentration profile at the base-emitter junction is different from that of the base-collector junction.
Anyway, now, connecting the 5V from the Arduino to the base directly just testing fully saturates the power transistor, but doing so shutdown the board in less than a second.

Sep 22, 3 0. I suppose that you have made certain of your wiring? Your name or email address: All this little factoids make me think your expectations of the transistor, when wired as a darlington, are too high.
If you interchange the collector and emitter of a modern planer BJT transistor, the Transjstor will be much less and the collector breakdown voltage is now equal to the transsistor breakdown which is usually only about 5V.
As a result, you have to drive the Darlington harder than you think you need to. Thank you in advance. In any event, compound transistor connections aren’t magic. I’m going to put 8 diodes around the two H bridges thanks for the head up.
