Impressive diode for LV applications :

Hi,

Yes, they call it "ideal diode", but indeed it´s an active circuit that drives a MOSFET.

The forward voltage drop is impressive.
But everything else is worse. Especially the timing. A usual diode has sitching timing in the nanoseconds, this one goes up to milliseconds.

I think there are not much applicatons where this device can be used.
I used it as low loss switchover of two DC power supplies.

I guess one can not even use it for mains frequency applications.

Great for current steering in a small battery usb backup situation. About to use it
in a USB ESP8266 Module application with gas sensor for powering the gas
sensor from USB supplied to ESP8266.

I cannot predict the worlds applications for ANY device.......not sure how you can.

No, not a Ghz mixer diode. Nor a 1000A diode for mains. Nor a diode to generate
energy on its own. Or a diode that switches in 1 femto second.

I do not see any Trr times in datasheet, just enable times, which I do not care about.


Regards, Dana.
 

Those are mostly for switchover between power supplies and/or batteries.

Here's an ideal diode bridge driver that works up to 600Hz for AC power rectification.
