Re: Reverse polarity AND flyback protection

2006-07-19 by Ryan

Wait a sec....

Looking at the datasheet for the IRL520, it shows a zener across the
drain & source.  It says the diode forward voltage is 1.3 volts.  Does
this mean anything more than that will be shorted to ground (in my
schematic)?  If so, the polarity protection will work, and I don't
need the extra diode (D2)....  Although it does say the D-S breakdown
voltage is 100V, and I don't know that the solenoid won't create
spikes above that...

Thanks in advance,
