Flyback option and 30V TS diode and IAC flyback
« on: August 12, 2010, 02:24:09 am »
Hello

I have High-Z injectors and mounted High-Z Flyback (SMB + 20V) . recently installed recommended 30V TS diode between flyback pad and +12V BAT.
Did not I should change 20V diode on 6.8V or SMB ?
I do not want to burn FET...

And second question - Can I connect the flyback diodes which safeguard the FET drives IAC (BOSCH duecoil) to the flyback pads which now is connected to +12V through 30V TS diode.

Thanks for answer

iac, boost solenoid .. need normal diode(0.7voltage drop). So for every iac,boost solenoid... you need one diode.

OK , i can connect this diode to flyback pad before 30V TS diode, do I have connect to +12V BAT ?

Why boost (or any other solenois except IAC) needs diode? Normal diode gives smooth, slow closing. Do we need it for BC?
