Blocking Diode
Ideal Diodes Reduce Power Waste In Battery Systems
A diode’s electricity conducting direction is called its forward direction and its blocking direction is called its reverse direction. Solid state diodes made of silicon exhibit a drop in voltage when forward conducting. Standard silicon diodes exhibit a forward voltage drop of 0.50 to 0.70 volts in the forward direction. Schotkey silicon diodes exhibit a forward voltage drop of 0.25 to 0.30 volts in the forward direction. Power loss in the diode is roughly equal to the forward current multiplied by the forward voltage drop. Thus a battery which supplies 10 amps through a silicon diode with a forward voltage drop of 0.50 V will exhibit 5 watts of power lost to heat.
Ideal diode circuits permits today’s designer to replace silicon diodes with a low resistance N-Channel Field Effect Transistor (N-FET). Implemented within a small integrated circuit package, the ideal diode circuit monitors the voltage drop across the source and drain of an N Channel FET. The circuit turns the N-FET on and off as required to permit unidirectional current flow - just like a solid state diode, but with far less power loss. Today’s modest N-Channel FETs have an on-time drain-source resistance of 0.005 ohms. Such a device when used with a 10 Amp battery system would exhibit a power loss of ((10 * 10) * 0.005) = 0.5 W.
Using an ideal diode, power loss in high current battery systems may be reduced by a factor of ten or more when compared to standard silicon diode performance. This energy savings will improve a user’s experience of perceived battery life.

Is a Rectifier Diode the same thing as a Blocking Diode when using Solar panels?
I was rigging up a small DYI solar panel kit for the first time and lost a blocking diode in my kit. I went to the electronics store, and the only diodes I could find were Rectifier diodes that had the same Amp rating.
Will these work?
IMPORTANT detail. this is being used in a DC to DC application. not DC to AC.
The key thing to remember is that a rectifier diode is used to make a rectifier which converts DC to AC so you can use it for household applications. A blocking diode simply acts as a diode that blocks current from flowing back into the solar panel and damaging the panel itself.
If your applications are DC, then you don't need rectifiers. You just need a simple diode at the same or higher voltage rating as your solar panel.
Do you have a (stalled? inefficient?) micro-hydro or solar/wind project?
