I am very intetrested in a part that STmicroelectronics manufactured, and I don't know if they still do, or if there is a replacement.
The part is a ulta-low Vf schottky diode, with a quoted (datasheet) Vf of 120mV at 10A. I have not come across a diode with anywhere near this Vf (at any reasonable current, 1A being reasonable).
Most suppliers list this as an obsolete part, but Digikey lists it as still active (zero stock) with a minimum of 3000. I want less than a tenth of that number! And even if I order, they may come back and say no-dice.
It would appear that a TI part (the SM74611) has a lower Vf (claimed 26mV at 8A), BUT this is not a real diode, it is a so-called "smart" diode. Digikey has that part if you wish to look up how it works. Needless to say that although it is rather unique, it does not have the characteristics of a genuine diode.
Trying to contact ST has been a nightmare, and I still haven't managed to, to ask if there is an equivilant.
Is anyone aware of a replacement, or of another ultra-low Vf schottky?
Cheers, MM
