low-C schottky

Snarl. Skyworks has discontinued their 0.25 pF SOD-323 schottky diode, the SMS7621-011...

and replaced it with an SC-79 that's basicly invisible and that has a polarity mark that is absolutely invisible. Since they mark some of their diodes on the anode and some on the cathode, the invisibility is just as well, I suppose.



I'm not enthusiastic about changing six or eight PCB layouts to accept this little horror.



So, a while back in a thread I can't find, somebody mentioned a similar part, a European-type part number maybe... does anybody remember what it might be?



There is also a Metelics part that might be a sub... I know about that one.



Thanks,



John

That's a PIN diode, but has interesting characteristics for RF switching.

Where is it available in small quantities?

Sorry...

We didn't come out with a source

Might it not be simpler to purchase whatever stock is out there to keep you going for however long ?
