What diode is this?

it seems so hard to find... any alternative for this?

SD50

Tnx...

It's in a TO92 package, right?

I don't see why you couldn't substitute a 1N914 or 1N4148 switching diode. Different package (DO-35), but as long as there's room ... why not?

i dunno....

can i use that any of that 2 as alternative of this?

Hello,

Can you make a photo of it?
In what circuit is the diode used?

Greetings,
Bertus

The only datasheet I could find for a SD50 indicates that diode is in a TO92 package, has a reverse breakdown voltage of 50v, and a maximum average current of 25mA.

The 1N914 and 1N4148 both have a maximum average current of 100mA and reverse breakdown voltage of 100v.

here it is..

any alternatives for SD50 , 2n3668 SCR and BC 148 Transistor? pls... help...

Thanks in Advance.....

That's not a very good charger design. There's a better one in the projects collection forum.

what's the title of the design?

Hi..


Did you completed that project battery charging model.

expecting your reply soon
