There are no zeners. The diodes are Schottkys, but could be replaced by 1N4148s, now that I know how much current your solenoid requires. If you omit the diodes, you risk destroying your transistors. The diodes absorb the flyback voltage that will otherwise occur each time the solenoid current is interrupted.leonel said:I tried again and didn´t work.
There are two thinks i'm not doing:
1st: i'm not putting diodo zener
2nd: i don't know
