[sdiy] 1S2473 vs. 1N4148 diode specs

[Synthusiast]

Hi again all,

Thanks for all the responses. :)

I was reverse engineering the battery backup circuit of the Roland Jupiter-6
and wanted to know if the 1S2473 diodes Roland used for this circuit could
be replaced by commonly available 1N4148 diodes. And the answer to that is
yes, though the path is a little long. I was told the 1S2473 is compatible
with the ECG519 diode and I found out the ECG519 is compatible with the
1N914 diode, which is compatible with the 1N4148 diode ;) So the 1S2374 is a
plain normal diode and couldn't even be a Schottki diode, as I learned the
reverse current leakage of those diodes would ruin the non-chargeable
Lithium cell when used in a battery backup circuit.

Why I wanted a battery backup circuit in the first place? Well, I performed
Old Crow's battery replacement for my Polysix and was wondering if the
voltage drop could be reduced by using different diodes than the 1N4148 I
used. But as even Roland used these kind of diodes, I'll keep my 1N4148 in
the circuit and be happy with it :-)

Cheers,
